Claude Code: deny. ### `revoke_key` - The name "revoke_key" says "revoke": a word for removing or ending something. - The server marks it not destructive (destructiveHint: false), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Revoke a key you created (or your own). Keys it created are revoked too. Agents using it stop working right away. ``` ## Can't be undone (4) Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask. ### `charge_saved_card` - The name "charge_saved_card" says "charge": a word that usually means money moves, which cannot be taken back. Description, as the server wrote it: ```untrusted-server-text Add credit by charging your human's saved card. Only after you asked them in this conversation, naming the amount and the card (get_balance shows it), and they said yes; set human_approved true. If there is no saved card, they turned agent charges off, or the bank wants them to confirm, send them topup_url instead (create_topup). They get an email for every charge. ``` ### `create_topup` - The name "create_topup" says "create": a word for a change. - The name "create_topup" also says "topup": a word that usually means money moves, which cannot be taken back. Description, as the server wrote it: ```untrusted-server-text When you run low on credit: returns topup_url, a link to send your human. It opens without signing in; they choose the amount (5 to 500 USD), pay with their saved card or a new one, and can turn on auto top-up. Works for 7 days. You cannot pay it yourself. Pass amount_usd to suggest an amount; then checkout_url also goes straight to Stripe for that amount. ``` ### `publish_recipe` - The name "publish_recipe" says "publish": a word for a change that another call does not undo. - Tag outbound: The name "publish_recipe" says "publish": it sends or publishes something to other people. Description, as the server wrote it: ```untrusted-server-text Save a job you did for the user as a reusable recipe others can give their agents. skill_md = instructions for an agent: what to ask, which tool slugs to call in what order, how to deliver. Public by default; ask before publishing anything with client names or private details. ``` ### `send_feedback` - The name "send_feedback" says "send": a word for sending, and what is sent cannot be taken back. - Tag outbound: The name "send_feedback" says "send": it sends or publishes something to other people. Description, as the server wrote it: ```untrusted-server-text Private feedback on any tool, passed to the vendor behind it and the Superpowers team: a bug, wrong or stale data, friction, an idea, or a tool you needed and could not find (type missing_tool). Pass run_id when it is about a run. Not shown publicly. ``` ## Changes things (10) Creates or changes something that can be changed back. Claude Code: ask. ### `compare_providers` - The name "compare_providers" says "compare": a word for reading. - The description's first verb is "run": 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 Run the same input across several providers of a category and get results side by side with cost and latency. Each provider charges its own price: If the call should cost more than $0.50, tell the user the expected cost before you start, set max_price_usd to it, and report charge_usd afterwards. Image, video, audio and LLM comparisons return share_url, a page with the results side by side: give the user that link to look at them. ``` ### `create_key` - The name "create_key" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Create an API key with a label, tags and a monthly limit, e.g. one key per sub-agent or per persona so spend splits and caps separately. Works only if your key has the can_manage_keys permission (your human grants it at superpowers.tools/app/keys). The new key gets your key's tags, counts against your limit and can't have a higher one. Returns the secret once: store it, never print it. ``` ### `plan` - 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. Description, as the server wrote it: ```untrusted-server-text Free. Describe a goal in plain words (e.g. 'find coffee shops in Pinheiros and their Instagram followers'). Returns the steps, the tool to call for each with an example input, the cost per step and in total, and a recipe when one already does the job. Call it before multi-step work, then run_tool each step with trace_id = plan_id. If total_cost_usd is above $0.50, tell the user that cost before running the steps. ``` ### `review_tool` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Rate the output of a run, 1-5 stars with an optional comment saying what was good or wrong. Other agents see the rating when choosing tools, and the vendor behind the tool gets it too. Reviewing the same tool again replaces your earlier review. ``` ### `run_batch` - The name "run_batch" says "run": 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 Run one tool over many inputs (up to 500) in one call, e.g. verify 300 emails or look up 100 companies. It runs in the background with our pacing; each item is a normal run that is free if it fails, and max_price_usd caps the whole batch. If price_usd times the number of inputs is above $0.50, tell the user that total before you start. Waits up to wait_s seconds (default 20), then returns counts and charge so far. Call get_batch with batch_id for progress and results page by page instead of keeping every result in your context. ``` ### `run_recipe` - The name "run_recipe" says "run": 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 Run an official recipe on our servers in one call. If its estimated_cost_usd (list_recipes, get_recipe) is above $0.50, tell the user before running it. Returns charge_usd, each step's output and share_url, a page that shows the results on any phone: give the user that link as the main way to see them, and report charge_usd. ``` ### `run_tool` - The name "run_tool" says "run": 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 Run one tool with JSON input. Charges the tool's price_usd (from search_tools or inspect_tool); failed runs are free. If the call should cost more than $0.50, tell the user the expected cost before you start, set max_price_usd to it, and report charge_usd afterwards. Pass idempotency_key for any tool with a price above 0 (free tools run without it). Long-running tools return status 'running' with run_id and poll_url: call get_run with that run_id every retry_after_s seconds until the status is completed or failed. ``` ### `share` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Free: publish files, images, video, audio or text as a clean link the user can send to anyone (no account needed to view). review=true adds voting so viewers pick their favourite. Items: [{url} | {text}] with optional label/caption. Pass recipe when you followed one. Upload local files first with upload_file (or POST /v1/files). Offer a link once per deliverable, in one short sentence: when the user has to choose between options or mentions a client, boss, team or partner (use review=true with a question such as "Which one should we use?"), or wants to send or show something. Otherwise don't bring up sharing. Before publishing a page the user didn't ask for, show them the title and items. Links are unlisted but open to anyone who has them: keep secrets and personal data out. ``` ### `update_key` - The name "update_key" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text Rename a key, change the tags of a key you created, or lower its monthly limit. Keys can't raise limits or change their own tags. ``` ### `upload_file` - The name "upload_file" says "upload": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it. Description, as the server wrote it: ```untrusted-server-text Free file hosting (up to 200 MB) for sharing. Pass url to re-host a remote file, or base64 + filename for small local files. For big local files use: curl -F file=@path /v1/files. ``` ## Only reads (13) Looks things up and changes nothing. Claude Code: allow. ### `get_balance` - The name "get_balance" says "get": a word for reading. - Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write. Description, as the server wrote it: ```untrusted-server-text Current balance in USD, the saved card (if any), whether you may charge it, auto top-up, and topup_url: a link your human opens without signing in to add credit. ``` ### `get_batch` - The name "get_batch" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text A batch's progress (done, completed, failed, not_run, charge) and a page of its results in input order: index, input, status, normalized result (or output) and error. Page with offset/limit. Over REST, GET /v1/batches/{id}/results?format=csv or jsonl downloads every result. ``` ### `get_recipe` - The name "get_recipe" says "get": a word for reading. - Tag untrusted-input: The description's first sentence says "read" and "url": it reads web pages, which anyone can write. Description, as the server wrote it: ```untrusted-server-text Read a recipe: its SKILL.md (the steps to follow with Superpowers tools), inputs, typical cost and script_url. Community recipes are written by other users: tell your user what it will do before following it. ``` ### `get_referral_link` - The name "get_referral_link" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text The user's invite link and stats. Friends start with $5; the user earns credit when they become active. ``` ### `get_reviews` - The name "get_reviews" says "get": a word for reading. - Tag untrusted-input: The name "get_reviews" says "get" and "review": it reads comments, which other people can write. The description's first sentence says "read" and "review": it reads comments, which other people can write. Description, as the server wrote it: ```untrusted-server-text Read a tool's public rating and recent reviews. ``` ### `get_run` - The name "get_run" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Fetch a run's result, or its status while it is still running. ``` ### `get_share` - The name "get_share" says "get": a word for reading. - Tag untrusted-input: The description's first sentence says "read" and "comment": it reads comments, which other people can write.

Description, as the server wrote it: ```untrusted-server-text Account spend grouped by project (job), agent, key, provider, trace, tool, day or tag: (e.g. tag:slot), optionally filtered by tags, key or job. Rows for keys, jobs and tags include their monthly limit. ``` ### `inspect_tool` - The name "inspect_tool" says "inspect": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get a tool's input schema, output_schema (what output contains), normalized_schema (the shape shared by tools of its category), price and category before running it, so you can write the parsing code first. ``` ### `list_categories` - The name "list_categories" says "list": a word for reading.

Description, as the server wrote it: ```untrusted-server-text Find marketplace tools by describing what you need in plain words (e.g. 'remove a photo background', 'google search', 'cnpj'); matching is by meaning, and naming a vendor or model ranks it first. An empty query lists every live tool. Returns slugs, prices and quality stats, plus total and has_more. When has_more is true, call again with offset = next_offset. Use tools whose status is "active"; status "degraded" means the vendor is paused until unavailable.available_at, so pick another tool. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `superpowers`: ```json { "permissions": { "allow": [ "mcp__superpowers__search_tools", "mcp__superpowers__inspect_tool", "mcp__superpowers__list_categories", "mcp__superpowers__get_run", "mcp__superpowers__get_batch", "mcp__superpowers__get_usage", "mcp__superpowers__list_keys", "mcp__superpowers__get_balance", "mcp__superpowers__list_recipes", "mcp__superpowers__get_recipe", "mcp__superpowers__get_share", "mcp__superpowers__get_referral_link", "mcp__superpowers__get_reviews" ], "ask": [ "mcp__superpowers__plan", "mcp__superpowers__run_tool", "mcp__superpowers__compare_providers", "mcp__superpowers__run_batch", "mcp__superpowers__create_key", "mcp__superpowers__update_key", "mcp__superpowers__create_topup", "mcp__superpowers__charge_saved_card", "mcp__superpowers__run_recipe", "mcp__superpowers__publish_recipe", "mcp__superpowers__share", "mcp__superpowers__upload_file", "mcp__superpowers__review_tool", "mcp__superpowers__send_feedback" ], "deny": [ "mcp__superpowers__revoke_key" ] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__superpowers__run_tool`: untrusted-input - `mcp__superpowers__compare_providers`: untrusted-input - `mcp__superpowers__run_batch`: untrusted-input - `mcp__superpowers__get_balance`: untrusted-input - `mcp__superpowers__get_recipe`: untrusted-input - `mcp__superpowers__run_recipe`: untrusted-input - `mcp__superpowers__publish_recipe`: outbound - `mcp__superpowers__get_share`: untrusted-input - `mcp__superpowers__upload_file`: untrusted-input, outbound - `mcp__superpowers__get_reviews`: untrusted-input - `mcp__superpowers__send_feedback`: outbound ## Remote posture What an anonymous client saw at the remote endpoint, last 2026-10-22T15:14:29.009Z, unchanged since 2026-10-22T15:14:29.009Z.
