Description, as the server wrote it: ```untrusted-server-text Deletes one of the account's API keys, by id or by name.

Your SOURCE (hero) VM is NOT part of the stack and is NOT deleted - it was the always-on baseline member but it is your own VM; delete_instance it separately if you no longer need it. Pass stack_name + stack_id from list_clusters. Deleting extra members individually does NOT work (the autoscaling group re-creates them under load) - this deletes the group itself. The managed database / external store the cluster used is NOT touched (data safety); delete_database it separately when you are done with the data.

Pass the numeric id from list_deployments. IMPORTANT: its managed datastores are NOT deleted (data safety): its database, Redis and Qdrant keep running and billing, and this tool returns each id so you can delete_database / delete_relational_database / delete_redis / delete_qdrant them when you're done with the data. Cannot be undone. ``` ### `delete_dns_entry` - The name "delete_dns_entry" says "delete": a word for removing or ending something. - The server marks it destructive (destructiveHint: true). - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Removes one public name (a DNS entry), by its id from list_dns_entries or by the name itself. The name stops serving at once, and anything reached through it (a site, an API, an OAuth callback) stops working with it. When the name belongs to one of your instances or deployments, that instance's own list of its names is updated too, the way the console's DNS view does it; the instance, its app and its data are untouched. The first call removes nothing: it shows the entry for the user to approve; call again with confirm:true only after their yes. Use it to clear the names a release_domain refusal (DOMAIN_IN_USE) lists. redu's own platform names cannot be removed. ``` ### `delete_instance` - The name "delete_instance" says "delete": a word for removing or ending something. - The description says "Permanently deletes". - The server marks it destructive (destructiveHint: true). - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it: ```untrusted-server-text Permanently deletes a block storage volume and the data on it. This cannot be undone. The volume must be 'available' (detached) - detach_volume it first, and note you cannot detach a running instance's boot disk. A volume left behind after a restore keeps billing, so delete the ones you no longer need. Any BACKUP the volume was restored from is independent and survives this. ``` ### `release_domain` - The description's first verb is "remove": a word for removing or ending something. - The server marks it destructive (destructiveHint: true). - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Removes a custom domain from this account: a verified domain is no longer verified for it (using it again needs a new TXT check), and a pending claim is cancelled. The first call releases nothing: it shows the domain for the user to approve; call again with confirm:true only after their yes. The second call reports the platform's answer: released, or refused. A refusal because public names still use the domain (DOMAIN_IN_USE) lists those names, each with its id: remove each with delete_dns_entry (it asks for the user's yes first), then call this again. Releasing a domain deletes no deployment, instance or cluster. ``` ### `upgrade_to_ha` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true). - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Findings: info long-description Description, as the server wrote it: ```untrusted-server-text Turns an EXISTING, running single-machine managed Postgres or ClickHouse into a THREE-machine highly available cluster, in place, keeping the data and the same username, password and database name. Use this when the user has a live database and wants it to survive a machine or host failure: they do NOT have to create a new one and migrate by hand. How it works: a full backup is taken first (a safety copy while the upgrade runs, deleted when it ends: the old machine is never touched and stays the restore point), the cluster is built alongside, the data is copied in and verified by counting both sides, and only then does the database's address move to the load balancer. The original machine is left running and untouched throughout, so a failure changes nothing and the user is never without a database. SAY THREE THINGS TO THE USER AND GET A YES BEFORE CALLING: (1) COST, it becomes three machines behind a load balancer instead of one, so roughly 3x the hourly rate, and the old single machine keeps billing for 3 days, until it is removed automatically; (2) WRITE LOSS, anything written to the old machine during the copy is not carried over (see acknowledge_write_loss); (3) THEY MUST REPOINT THE APP afterwards, the connection address changes and nothing redeploys their app for them. Takes about 20 minutes and returns immediately; poll list_databases / list_clickhouse_databases until the address changes. Requires a payment method: high availability is not available on the no-card trial. ⛔ CLICKHOUSE ONLY, a FOURTH thing to say: after the upgrade every table has to use a REPLICATED engine. The existing tables are converted for them as part of the copy, but any NEW `CREATE TABLE ... ENGINE = MergeTree` is refused from then on (ClickHouse error 56) and has to be written `ENGINE = ReplicatedMergeTree`. It is refused rather than accepted because a plain MergeTree on three machines replicates its schema and not its rows, which would leave two of the three answering with an empty table and no error. If their app ships plain-MergeTree migrations (Plausible, PostHog and Langfuse all do), those migrations will fail after the upgrade and they should stay on the single machine. For the app tier rather than the database, use upgrade_to_cluster instead. ``` ## Changes things (41) Creates or changes something that can be changed back. Claude Code: ask. ### `attach_volume` - The name "attach_volume" says "attach": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Attaches an EXISTING block volume to a running instance as an extra disk. This is how you finish a RESTORE after a VM is gone: restore_backup (volumeName) rebuilds the data into a new volume, then attach_volume puts that volume on a replacement instance - then SSH in (get_ssh_command) and mount it (`lsblk` to find it, usually /dev/vdb, then `mount /dev/vdb /mnt/...`). The volume must be 'available' (not already in-use - detach_volume it first) and in the same project. Attaching does NOT mount or boot from it: the instance keeps booting from its own root disk, the volume shows up as an extra block device. Poll list_volumes until status is 'in-use'. ``` ### `check_agent_prerequisites` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Checks if your account has everything needed to run autonomous coding agents. Returns a checklist: API key validity, private network, SSH keypair, and billing. Safe to call anytime - read-only. Call this first before create_controller. ``` ### `check_deploy_prerequisites` - The name "check_deploy_prerequisites" says "deploy": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text The deploy ENTRY GATE - run this first when a user wants to deploy. Verifies the account is ready and AUTO-SELECTS the network_id + keypair_name to pass to deploy_app (so you never hunt for them): (1) account reachable + quota, (2) a private network (picks your default - every account has one), (3) an SSH keypair (if you have none, returns ssh_key_recipe: the exact local ssh-keygen → import_keypair → write SSH_KEY_LOCATION-to-.env steps - run them, in yolo mode without asking). Returns { ready, network_id, keypair_name, missing, ssh_key_recipe }. ``` ### `create_api_key` - The name "create_api_key" says "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Findings: info credentials-mention Description, as the server wrote it: ```untrusted-server-text Mints a NEW least-privilege redu API key for a deployed app or automation to use (e.g. to add a backup feature). GUARDRAIL: the first call does NOT create anything. It returns a confirmation the user must approve, because a key is a long-lived credential that acts on the account and ANY usage of it is BILLED to the account owner. Show the user the name, the exact scopes, and the billing notice, get their explicit approval, then call again with confirm:true. This is required even in yolo/auto mode. The secret is returned ONCE. ``` ### `create_backup` - The name "create_backup" says "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Creates a backup, by volumeId or by instanceId (the instance's volume is resolved for you). The backup is held independently of the instance, so it survives the VM. Poll list_backups until the new backup is available. ``` ### `create_clickhouse` - The name "create_clickhouse" says "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Provisions a managed ClickHouse database (OLAP / columnar analytics engine, Apache-2.0) on a dedicated VM on your private network - its OWN resource, NOT a relational database. Requires a recent plan_managed_datastore. Use it for analytics / observability workloads that need a column store (PostHog, Langfuse, event analytics, time-series). It is PRIVATE - reachable only from another instance on the same private network, via the DB's internal/private IP on the ClickHouse HTTP port 8123 (CLICKHOUSE_HOST/PORT/USER/PASSWORD/DB env, http://host:8123). Get the ids from plan_managed_datastore/list_flavors (use m1.small+ - ClickHouse needs >=2GB RAM), list_private_networks, list_keypairs. Provisioning takes ~5 min; poll list_clickhouse_databases until status='ready'. HIGH AVAILABILITY: pass ha:true to get THREE machines on three different physical hosts behind a load balancer instead of one: all three take reads and writes, so losing a machine costs no failover and no write pause, and the replacement refills itself from the survivors before it serves again. It costs about 3x the hourly rate (three machines instead of one) and provisions more slowly. Default is a single machine; show the user the price difference and get an explicit yes before turning HA on. ``` ### `create_controller` - The name "create_controller" says "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Generates and uploads an SSH keypair if you don't have one. The VM bootstraps itself - no SSH or VPN needed. After ~7 minutes, authorize the fleet (run the authorize.sh one-liner it returns) then call trigger_agent_batch. ``` ### `create_database` - The name "create_database" says "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Provisions a managed PostgreSQL database on a dedicated VM on your private network. Requires a recent plan_managed_datastore. For app deployments, prefer deploy_app database:'managed' so plan_deploy includes and wires the DB automatically. It is PRIVATE - reachable only from another instance on the same private network, via the DB's internal/private IP (not a public address). Get the ids from plan_managed_datastore/list_flavors/list_private_networks/list_keypairs. Provisioning takes ~5 min; poll list_databases until status='ready', then the connection details (private_ip, port 5432, db_name, db_user) are populated. HIGH AVAILABILITY: pass ha:true to get THREE machines on three different physical hosts behind a load balancer with automatic failover instead of one machine: the database survives losing a machine, and nobody has to fail it over by hand. It costs about 3x the hourly rate (three machines instead of one), it provisions more slowly, and one connection string still serves the whole thing. Default is a single machine; show the user the price difference and get an explicit yes before turning HA on. ``` ### `create_instance` - The name "create_instance" says "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Creates a raw compute instance for custom OS/cloud-init workflows. For app/source deployments, prefer check_deploy_prerequisites -> plan_deploy -> deploy_app/deploy_compose; do not use create_instance as a shortcut around the deployment plan. Requires a recent plan_instance. For reduOS, set cloud_init_template='reduos' and flavor m1.xlarge (16GB). SSH keypair must exist. For a public web app on a raw VM, pass dns_entries (gives a .redu.cloud URL through redu's automatic public proxy). The origin app should listen on dns_entries[].port; do not install nginx on the VM unless the app itself needs it, because redu.cloud already creates the public Nginx proxy host. ``` ### `create_media_space` - The name "create_media_space" says "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Creates a private Redu media space: a small NFS VM backed by a persistent volume, intended for WordPress/WooCommerce wp-content/uploads in autoscaling clusters. Prefer letting deploy_app/deploy_compose create this by passing create_media_space:true after plan_deploy approval; use this tool when manually preparing or reusing shared uploads storage. ``` ### `create_qdrant` - The name "create_qdrant" says "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Provisions a managed Qdrant vector database on a dedicated VM. Requires a recent plan_managed_datastore (engine 'qdrant'). Reachable from your private network at :6333 (REST) and :6334 (gRPC), and at a public https URL; every request must carry the api-key header (always required). Backups: set_managed_backups with service 'qdrant'. FOR AN APP YOU DEPLOY YOU DO NOT NEED THIS: report vector_engines:['qdrant'] in send_signals and the deploy starts and wires a managed Qdrant itself (a compose stack's own qdrant service is replaced by it). Provisioning takes a few minutes; poll list_qdrant until status='ready'. ``` ### `create_redis` - The name "create_redis" says "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Provisions a managed Redis instance on a dedicated VM on your private network. Requires a recent plan_managed_datastore. It is PRIVATE - reachable only from another instance on the same private network, via its internal/private IP on port 6379 (not a public address). AUTH (requirepass) is always enabled. Get the ids from plan_managed_datastore/list_flavors, list_private_networks (or check_deploy_prerequisites), list_keypairs - use the SAME network_id as the app that will connect. Provisioning takes ~5 min; poll list_redis until status='ready', then the connection details (private_ip, port 6379) are populated. Wire an app with REDIS_URL=redis://:@:6379 (pass it via deploy_app env). ``` ### `create_relational_database` - The name "create_relational_database" says "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Provisions a managed MySQL (or MariaDB) database on a dedicated VM on your private network - the relational-database resource (use this instead of create_database when the app needs MySQL/MariaDB, e.g. WordPress, NextCloud, Matomo, many PHP/LAMP apps). Requires a recent plan_managed_datastore. For app deployments, prefer deploy_app database:'managed' with db_engine mysql/mariadb so plan_deploy includes and wires the DB automatically. It is PRIVATE - reachable only from another instance on the same private network, via the DB's internal/private IP (port 3306), not a public address. Get the ids from plan_managed_datastore/list_flavors/list_private_networks/list_keypairs. Provisioning takes ~5 min; poll list_relational_databases until status='ready', then the connection details (private_ip, port 3306, db_name, db_user) are populated. MySQL is created with mysql_native_password auth so older clients/apps connect cleanly. (ClickHouse is a separate resource - use create_clickhouse / list_clickhouse_databases.) ``` ### `create_snapshot` - The name "create_snapshot" says "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it: ```untrusted-server-text Deploys an app to a VM and exposes it at a public https://-.redu.cloud URL. The container is built ON the VM. PREREQS - run check_deploy_prerequisites first for network_id + keypair_name, then plan_deploy for cost approval. Source can be git repo or prepare_upload source_token. PORT must be the real app listen port. DATASTORES ARE MANAGED BY DEFAULT: each one you reported in send_signals runs as a managed store started at your signal and is wired with no settings (DATABASE_URL and PG*/MYSQL_*, REDIS_URL, QDRANT_URL with QDRANT_API_KEY); without a signal, pass database:'managed' (db_engine 'postgres', or 'mysql'/'mariadb' for WordPress/Matomo/LAMP), redis:'managed' or qdrant:'managed'. For WordPress/WooCommerce cluster intent, do not use generic stateless deploy: pass app_profile, cluster_target:true, database:'managed', db_engine:'mariadb' or 'mysql', cluster_media_mode:'media_space', and either media_space_id or create_media_space:true. Redu mounts the media space into wp-content/uploads and refuses unsafe local uploads. Build+provision takes minutes; poll list_deployments/get_deployment. ROUTE: when plan_deploy returned recommended_route:'compose', do NOT use this tool for that folder: deploy its recommended_compose_file with deploy_compose (compose_file, recommended_service as service, recommended_port as port), for the reason in route_reason. The exceptions are route_next's: this tool builds the folder's Dockerfile instead only if the user asked for a build from source, the user changed the code the Dockerfile builds (check git status and unpushed commits in the folder), or the image cannot be pulled. ``` ### `deploy_compose` - The name "deploy_compose" says "deploy": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Findings: high sensitive-path, high sensitive-path Description, as the server wrote it: ```untrusted-server-text Deploys a MULTI-CONTAINER app - a repo that ships docker-compose.yml / compose.yaml - onto ONE VM via podman-compose, and exposes one or more services at redu.cloud URLs. Use this instead of deploy_app when the repo is a compose stack. Same prereqs + source modes as deploy_app; always run plan_deploy first. PORT is the HOST port for the exposed service. DATASTORES ARE MANAGED BY DEFAULT: each one you reported in send_signals runs as a managed store; the stack keeps its own settings, and its own copy of each store is replaced by a forwarder of the same name to the managed one (the stack's own user, password and database created there, its init scripts run once). Pass no database/redis/qdrant settings; 'compose' (the stack's own) only when the user asked for one VM. For WordPress/WooCommerce cluster intent, do not leave the compose db service/local uploads as state: pass app_profile, cluster_target:true, database:'managed', db_engine:'mariadb' or 'mysql', cluster_media_mode:'media_space', and either media_space_id or create_media_space:true. Redu writes an override file that points the WordPress service at managed DB env and mounts the media space into /var/www/html/wp-content/uploads. Poll get_deployment until ready. ROUTE: when plan_deploy returned recommended_route:'compose', this is the tool for that folder, even when it also has a Dockerfile: pass its recommended_compose_file as compose_file, recommended_service as service and recommended_port as port (the HOST port the app service publishes, not the port the app listens on inside its container). route_reason says why the platform deploys it that way, and route_next when to build the Dockerfile with deploy_app instead. ``` ### `deploy_overview` - The name "deploy_overview" says "deploy": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Orientation for deploying an app on redu.cloud: the end-to-end flow, the two source modes (git vs upload), how to handle a missing Dockerfile or a database, when (and when NOT) to split a deploy across multiple VMs, verifying a deploy functionally, and how to debug a failed build. Call this first when a user asks to deploy/ship/host an app and you're unsure where to start. ``` ### `deploy_vpn` - The name "deploy_vpn" says "deploy": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Stands up a redu VPN gateway (WireGuard tunnelled over wstunnel on WSS/443) on your PRIVATE network, so you (or your team) can reach the private IPs of the VMs you deployed on redu, over a single https endpoint - no UDP, no extra ports. This is the TENANT VPN for reaching your OWN deployed resources; it is NOT a general internet VPN. GUARDRAIL: the first call does NOT deploy - it returns the plan + hourly cost for approval, because it creates a BILLED VM. Show the user, get their explicit 'go', then call again with confirm:true (required even in yolo mode). The gateway asset is redu's, deployed onto YOUR VM (you can SSH in to read it). Fresh WireGuard keys are generated per deploy; the client PRIVATE key is returned ONCE and is never stored server-side. ``` ### `detach_volume` - The name "detach_volume" says "detach": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Detaches a block volume from an instance, leaving the volume (and its data) intact and 'available' to attach elsewhere. Unmount it INSIDE the guest first (`umount /mnt/...`) or you risk a dirty filesystem. You cannot detach an instance's ROOT/boot disk while it runs. Use this to move a data volume to another VM, or to free a restore target before restore_backup writes into it. Poll list_volumes until status is 'available'. ``` ### `get_domain_verification` - The name "get_domain_verification" says "get": a word for reading. - The description's first verb is "start": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Starts (or resumes) a claim on a custom domain and returns the DNS TXT record that proves it is the user's: they add it at the domain's DNS provider, then you call verify_domain. Until it verifies, list_domains shows the domain as pending. A pending claim's TXT value can change (values are specific to each account), so add exactly the value get_domain_verification returns now, never one saved earlier or seen on another account; if verify_domain keeps failing, call get_domain_verification again and update the record when the value differs. A name under redu.cloud needs no verification. ``` ### `import_keypair` - The name "import_keypair" says "import": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Findings: high sensitive-path Description, as the server wrote it: ```untrusted-server-text Registers an existing SSH public key on your account.

Pasting the same files costs you 20-29 KB of output for bytes the server already has. Otherwise (git mode) paste `redu_md` (cat redu.md), `compose_yaml`, `dockerfile`. Either way you do NOT read or interpret them; redu parses them SERVER-SIDE and returns (a) a short digest, (b) `pin_dname` so a redeploy keeps the SAME public URL, and (c) `preflight` - preemptive fixes for known failure patterns found in YOUR repo, each learned from a real failed build. Giving redu these files is the single highest-value thing you can do for a first deploy. picks the VM + managed-Postgres sizes, prices them at the real pricing_rules rates, and checks they FIT your quota - so a plan that can't provision is caught HERE, before any spend. You pass what you detected in the repo (runtime, port, needs_postgres/redis/clickhouse/vector_db); it returns resources + £/hr + £/mo + a feasibility verdict + a checkpoint summary to confirm with the user. Defaults: app VM m1.medium, managed Postgres m1.small, managed ClickHouse m1.medium; pass single_vm to collapse the app + Postgres onto one VM. SET needs_clickhouse:true FOR ANY ANALYTICS-SHAPED APP (Plausible, PostHog, Langfuse, Matomo, SigNoz, or anything with a clickhouse image / CLICKHOUSE_* env / a ClickHouse client dep): those products keep config in Postgres and EVERY EVENT in ClickHouse, so the events tier is a second VM with a second line on the bill: measured 2026-08-07, omitting it quoted GBP 53.29/mo for a GBP 65.99/mo deployment. It is sized, quota-checked and priced here; unlike Postgres and Redis it is not auto-wired by deploy_app, so the plan tells you to run plan_managed_datastore engine:'clickhouse' -> create_clickhouse and pass CLICKHOUSE_* env yourself. A Qdrant vector DB is managed like the other datastores (vector_engines in send_signals; qdrant:'managed' without a signal); pgvector lives in the managed Postgres. In a session with send_signals the platform sizes every machine by measurement, so heavy_build, memory_heavy and needs_compose change no size there. Any containerizable app works (node, python, go, ...) - it deploys as a container, so the language doesn't gate it. Set serves_http:false for a non-web repo (a library, CLI, or language runtime with no HTTP server) and it returns a clean not-a-web-service verdict instead of a costed VM plan. Set heavy_build:true for resource-heavy builds (compiled-from-source native code, a monorepo/turborepo build, a large Node heap) and it raises the app VM to a build-capable floor so the on-VM build doesn't get OOM-killed. Set memory_heavy:true for a RAM-forward app whose persistent state lives in a MANAGED DB / external store (Next.js like cal.com/cal.diy, Rails, Django, JVM/Java apps) - it sizes onto a memory-optimized SMALL-DISK flavor (m1.mem16/m1.mem32: full RAM, a lean 40 GB disk instead of 160 GB) that costs less and snapshots/clusters far faster; do NOT set it if the app keeps lots of data on local disk. Also returns a brand-named markdown report (Mermaid diagram + cost) to SHOW the user only in guided mode; write no file from it. Every deploy leaves TWO MANDATORY files at the repo root with DIFFERENT purposes, both written ONCE at the end from the deployment that actually ran (get_deployment), after you verified it works: redu-deploy-plan.md = what this run deployed, and redu.md = the DURABLE deploy memory the NEXT deploy reads. If a redu.md exists, READ it FIRST and reuse its known-good plan + recorded fixes; if NONE exists, one MUST be created at the end of the deploy (get_de… [1004 more characters not shown] ``` ### `plan_instance` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Pass ha:true to plan a highly available datastore (postgres or clickhouse): three machines instead of one, surviving the loss of a machine without manual failover, at roughly 3x the hourly rate. The returned plan carries the machine count so you can show the user the cost before anything is created. ``` ### `prepare_upload` - The name "prepare_upload" says "upload": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Findings: high sensitive-path, info credentials-mention, warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Returns the LOCAL shell commands to package your working directory and upload it for an upload-mode deploy (no git, no PAT). Run them in the user's terminal, capture `source_token` from the upload's JSON response, then call deploy_app with that source_token (omit repo). The upload authenticates AUTOMATICALLY with a short-lived ticket minted from your MCP credential - NO API key needed in the command and nothing secret is printed (it falls back to needing $REDU_API_KEY only if minting is unavailable).

Poll list_volumes for the restored volume. DISASTER RECOVERY (the original VM is gone, so its volume died with it): restore with volumeName to rebuild the data as a NEW volume. To bring the MACHINE back, pass that volume as create_instance's boot_volume_id - it boots from the restored disk, so the VM returns with its filesystem intact and nothing to mount. Use attach_volume instead only when you want the data as an EXTRA disk on an existing machine (then get_ssh_command -> lsblk -> mount). A restored volume is inert until it is booted from or attached. ``` ### `scaffold_local` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Findings: high sensitive-path Description, as the server wrote it: ```untrusted-server-text OPTIONAL preflight: returns a podman-compose.yml + .env so the user can run the app (and a throwaway local Postgres) on THEIR machine before deploying to redu - to see it run / sanity-check the container. Requires local podman/podman-compose. It's a suggestion, not a gate - skip it and go straight to deploy_app any time. Honest caveat: the local Postgres is NOT the managed Postgres, so a green local run does not prove the prod DB wiring. ``` ### `select_surface` - The name "select_surface" says "select": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text For a repo with SEVERAL runnable parts, call this BEFORE plan_deploy.

That is what this tool is for: a real product on a real brand. The cluster itself is untouched - same members, same load balancer, same data - only the name in front of it changes. Pass stack_name + stack_id from list_clusters. TWO RULES, and getting either wrong wastes a call: (1) A CUSTOM DOMAIN MUST BE VERIFIED FIRST. Call get_domain_verification for the TXT record, have the user add it at their DNS provider, then call verify_domain until it reports verified (list_domains shows what is already verified). Binding an unverified domain is refused, on purpose: without proof of ownership anyone could bind, and obtain a certificate for, a hostname that is not theirs. Also make sure the domain's own DNS actually points at this cluster, or it will verify and still not serve. (2) A redu.cloud NAME CANNOT BE FREELY CHOSEN. The redu.cloud base domain is shared by every customer, so names under it always keep a short-id suffix - the real form is `
