Invisible characters are shown as [U+XXXX]. > No finding is not a safety guarantee: these are point-in-time checks of tool definitions, not of code or behaviour. - Page: https://anlyon.dev/servers/io.github.ninihen1/flowstudio-mcp - JSON: https://anlyon.dev/api/v1/servers/io.github.ninihen1/flowstudio-mcp - Version: 1.0.0 (active) - Publisher: io.github.ninihen1 (GitHub account) - Runs: remote (streamable-http) - Sign-in to list tools: none - Repository: https://github.com/ninihen1/power-automate-mcp-skills - Metadata from the official MCP Registry, synced 2026-10-21T18:42:35.401Z Title and description, as the publisher wrote them: ```untrusted-server-text Power Automate MCP Server by Flow Studio Debug, build, and manage Power Automate cloud flows with AI agents ``` Scanned 2026-10-21T19:25:32.618Z over streamable-http. **30 tools: 2 can delete or cancel things, 8 change things and 20 only read.** | Group | Class | Tools | Claude Code | | --- | --- | --- | --- | | Deletes or cancels | destructive | 2 | deny | | Can't be undone | irreversible | 0 | ask | | Changes things | write | 8 | ask | | Only reads | read | 20 | allow | ## Exfil surface No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound. | Tag | Meaning | Tools | | --- | --- | --- | | private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__flowstudio__resolve_live_parameters` | | untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__flowstudio__resubmit_live_flow_run` `mcp__flowstudio__trigger_live_flow` | | outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none | ## Findings - **info** The word "credentials" in `get_live_flow` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention)) ```untrusted-server-text The input schema at properties.includeTriggerUrl.description mentions "credential". inputSchema.properties.includeTriggerUrl.description: "...so return the HTTP trigger URL. It is a credential: anyone holding it can run the flow." ``` ## Deletes or cancels (2) Removes, cancels or revokes something. Claude Code: deny. ### `cancel_live_flow_run` - The name "cancel_live_flow_run" says "cancel": a word for removing or ending something. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Cancel a currently running Power Automate flow run via the live PA API. Use after get_live_flow_runs to obtain the run name. Only runs with status "Running" can be cancelled. ``` ### `update_live_flow` - The name "update_live_flow" says "update": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Update or create a flow. Use `dryRun: true` to preview any change without writing. Omit flowName to create: definition and displayName are required. Give flowName to update: displayName and/or definition and/or connectionReferences. SURGICAL EDIT: pass `operations` — an ordered list of set/add/remove/merge ops on array-of-keys paths — to change one action or parameter without resending the whole definition. Provide EITHER operations OR definition; connectionReferences may accompany either and lands in the same save. WHOLE definition: call get_live_flow, mutate properties.definition, pass it here. RENAME: pass displayName alone. Power Automate rejects a PATCH carrying no flow content, so this re-saves the unchanged definition — the maker portal does the same. definition.description is required, and must be brief — we append " #flowstudio-mcp" to it. ``` ## Changes things (8) Creates or changes something that can be changed back. Claude Code: ask. ### `add_live_flow_to_solution` - The name "add_live_flow_to_solution" says "add": a word for a change. Description, as the server wrote it: ```untrusted-server-text Move a flow into a solution. Refuses if the flow is already in one. solutionId is optional — omit for the default solution. ``` ### `create_live_connection` - The name "create_live_connection" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Create a connection, or sign an existing one in again (pass connectionName). Shows a sign-in card where the person signs in; you never sign in for them. Without the card, give the person signInLink to open. Connectors that use a key or account details instead of a sign-in are refused: create those in Power Automate. ``` ### `report_bug` - 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 Report a Flow Studio MCP bug or missing capability, append text evidence, or check your reports. Free and available even after quota is reached. Do not include passwords, access tokens, secrets, or full flow definitions unless necessary. ``` ### `resubmit_live_flow_run` - The name "resubmit_live_flow_run" 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 Resubmit a failed or cancelled Power Automate flow run via the live PA API, re-using the original trigger payload. Discovers the trigger name from the flow definition automatically — no trigger name parameter needed. ``` ### `set_live_flow_state` - The name "set_live_flow_state" says "set": a word for a change. Description, as the server wrote it: ```untrusted-server-text Start or stop the flow you name. Reads the current state first and only calls Power Automate if a change is actually needed. ``` ### `test_live_connection` - 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 Test a connection, or run one operation on it. Without operationId it runs the connector's own connection test. With operationId it runs that operation and returns the raw reply: a GET operation, or a lookup the connector itself declares for a dropdown, list, schema or folder picker. Anything else is refused before a call is made. connectionName comes from list_live_connections; operation ids from describe_live_connector. ``` ### `trigger_live_flow` - The name "trigger_live_flow" says "trigger": 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 a flow on demand — the same as the maker portal's "Run flow" button. Works with Request triggers (HTTP request, manual Button, PowerApps) and with scheduled RECURRENCE flows, which run immediately; a scheduled flow takes no inputs, so passing `body` to one is refused. Pass trigger inputs as `body`. Automated connector triggers only fire from their source event. ``` ### `update_store_flow` - The name "update_store_flow" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text [Requires Pro+ plan] Update governance/metadata fields on a flow record in the Power Clarity store (description, business impact, owner team, tags, monitor flag, notification settings, etc.). Only fields provided are updated (merge semantics). Writes to the cache — does not call the Power Automate API. ``` ## Only reads (20) Looks things up and changes nothing. Claude Code: allow. ### `describe_live_connector` - The name "describe_live_connector" says "describe": a word for reading. Description, as the server wrote it: ```untrusted-server-text Describe a live Power Platform connector/API and its operations. Use mode=summary (default) to get a compact operation catalog. Use operationId to describe one operation, including inputs, outputs, dynamic parameter metadata, nextTool hints to call resolve_live_parameters, and an authored hint + canonical example shape (when one exists) to copy into update_live_flow. Use search without connectorName/apiName to search operations across connectors and get connection-aware suggestions. Use mode=full only when raw OpenAPI connector metadata is required. ``` ### `get_live_flow` - The name "get_live_flow" says "get": a word for reading. - Findings: info credentials-mention Description, as the server wrote it: ```untrusted-server-text Fetch the full native Power Automate flow JSON from the PA API, including the complete flow definition (triggers, actions, parameters, outputs). Returns the raw properties object exactly as the PA API returns it. Use this to inspect the full definition before calling update_live_flow with a modified definition. ``` ### `get_live_flow_run_action_outputs` - The name "get_live_flow_run_action_outputs" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Read the recorded inputs and outputs of actions in one flow run. Without actionName: the top-level actions (optionally filtered by name). With actionName: every execution of that action across foreach iterations, each with repetitionIndexes, status, error, and resolved inputs/outputs. Use iterationIndex to pin one iteration; omit it for all. TRIGGER PAYLOADS: set trigger=true with a runName to get that run's trigger inputs and outputs. No Compose workaround is needed. TRIGGER CHECKS: pass checkId (from get_live_flow_runs -> triggerChecks.recent[].checkId) to read a trigger evaluation that never became a run — that is how you see WHY a trigger is failing. Do not supply runName with a checkId. ``` ### `get_live_flow_run_error` - The name "get_live_flow_run_error" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Fetch error details for a specific flow run from the live Power Automate API. Lists every failed action with its error code and message to help diagnose what went wrong. ``` ### `get_live_flow_runs` - The name "get_live_flow_runs" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Fetch run history for a flow directly from Power Automate. Returns { runs, runCount, triggerChecks }: each run has name, status, startTime, endTime, trigger name/code, and any top-level error. IMPORTANT — no runs does NOT mean the flow is healthy. A trigger that fires and evaluates to nothing, or fails to evaluate, records a TRIGGER CHECK and never becomes a run. When there are no runs (or when includeTriggerChecks is set) this tool also reports the trigger check history, so "nothing ran" can be told apart from "the trigger has been failing". Read triggerChecks.byStatus before concluding a flow is fine. ``` ### `get_store_flow` - The name "get_store_flow" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Requires Pro+ plan] Get full details for a single Power Automate flow from the Power Clarity cache. Includes trigger URL, owners, state, run statistics, and governance metadata. Data is from the stored snapshot — not live from the Power Automate API. ``` ### `get_store_flow_runs` - The name "get_store_flow_runs" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Requires Pro+ plan] Get cached run history for a flow from the Power Clarity store. Defaults to the last 7 days. Returns startTime, endTime, status, duration (seconds), failedActions, and remediation hint per run. Data is from the stored snapshot — not live from the Power Automate API. ``` ### `get_store_flow_summary` - The name "get_store_flow_summary" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Requires Pro+ plan] Get aggregated run statistics for a flow from the Power Clarity cache: total runs, success count, failure count, success rate, fail rate, and average/max duration over a time window. Data is from the stored snapshot — not live from the Power Automate API. ``` ### `get_store_maker` - The name "get_store_maker" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Requires Pro+ plan] Get details for a single maker from the Power Clarity cache by their key (usually the AAD object ID). Includes flow/app counts and whether the account has been deleted. ``` ### `list_live_connections` - The name "list_live_connections" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List Power Platform connections in an environment directly from Power Automate. Returns id, displayName, connectorName, environment, createdBy (full object), authenticatedUser, statuses, overallStatus, createdTime, expirationTime, and connectionParameters for each connection. Pass search= to narrow the list and receive a paste-ready connectionReferenceTemplate plus action-side hostTemplate per connection — drop these into update_live_flow's connectionReferences and inputs.host without further edits. ``` ### `list_live_environments` - The name "list_live_environments" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List all Power Platform environments you belong to, directly from Power Automate. Returns id, displayName, sku, location, and state for each environment. mode=all (default) and mode=member: every environment you are a member of. mode=admin: only those you administer; errors rather than guessing if admin access cannot be determined. isAdmin means you hold the ListAnyFlow permission there — the capability list_live_flows mode=admin needs. It is null, never false, when the platform did not tell us. isMember is true for every environment returned. ``` ### `list_live_flows` - The name "list_live_flows" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List Power Automate flows in an environment. Returns id, displayName, state, triggerType, and lastModifiedTime for each flow. mode=owner (default): flows you own plus flows shared with you (personal + team), with full definitions. mode=admin: all flows in the environment (requires an admin account). mode=admin with includeDeleted=true also returns soft-deleted flows (state=Deleted) — the only way to find a deleted flow. If search is provided, results are filtered to flows whose displayName contains the search text. For large environments pagination is time-bounded — if nextLink is returned, pass it as continuationUrl to retrieve the next batch. ``` ### `list_skills` - The name "list_skills" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text Skill bundles: groups of the tools listed here that are used together for one task (diagnose-connection-references, build-flow, debug-flow, monitor-flow, discover, governance). Returns each bundle's one-line description and tool names. Use it when unsure which tools fit a request; tool_search "skill:" returns the bundle's full guidance and definitions. Non-billable. ``` ### `list_store_connections` - The name "list_store_connections" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Requires Pro+ plan] List all Power Platform connections from the Power Clarity cache. ``` ### `list_store_environments` - The name "list_store_environments" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Requires Pro+ plan] List all Power Platform environments from the Power Clarity cache. ``` ### `list_store_flows` - The name "list_store_flows" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Requires Pro+ plan] List Power Automate flows from the Power Clarity cache. Optionally filter by governance flags (monitor, notification rules). Returns key fields including trigger URL, state, and run failure rate. Data is from the stored snapshot — not live from the Power Automate API. ``` ### `list_store_makers` - The name "list_store_makers" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Requires Pro+ plan] List all makers (citizen developers / AAD users) from the Power Clarity cache. ``` ### `list_store_power_apps` - The name "list_store_power_apps" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text [Requires Pro+ plan] List all Power Apps canvas apps from the Power Clarity cache. ``` ### `resolve_live_parameters` - The name "resolve_live_parameters" says "resolve": a word for reading. - Tag private-data: The description's first sentence says "resolve" and "table": it reads databases. Description, as the server wrote it: ```untrusted-server-text Resolve a connector action's inputs the way the flow designer does: dropdown options, list and table columns, folder and file pickers — every input in one call, or one with parameterName. Reads only: it runs the lookups the designer runs, never an action. Pass values you have in parameters; pass a display name in match to get back the value to write into the flow. An input whose parent is not known yet has status "needs". Inputs inside an object are addressed by key (body/recipient/groupId). Omit connectionName and one is chosen. ``` ### `tool_search` - The name "tool_search" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find a tool listed here instead of guessing its name, and get its definition. Query forms: (1) "skill:" — a whole bundle; call list_skills for the names; (2) "select:name1,name2" — exact tools; (3) free text like "cancel run" — ranked against name and description. Non-billable. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `flowstudio`: ```json { "permissions": { "allow": [ "mcp__flowstudio__tool_search", "mcp__flowstudio__list_skills", "mcp__flowstudio__list_store_flows", "mcp__flowstudio__get_store_flow", "mcp__flowstudio__get_store_flow_runs", "mcp__flowstudio__get_store_flow_summary", "mcp__flowstudio__list_store_environments", "mcp__flowstudio__list_store_makers", "mcp__flowstudio__get_store_maker", "mcp__flowstudio__list_store_power_apps", "mcp__flowstudio__list_store_connections", "mcp__flowstudio__get_live_flow_runs", "mcp__flowstudio__get_live_flow_run_error", "mcp__flowstudio__get_live_flow_run_action_outputs", "mcp__flowstudio__get_live_flow", "mcp__flowstudio__list_live_environments", "mcp__flowstudio__list_live_flows", "mcp__flowstudio__list_live_connections", "mcp__flowstudio__describe_live_connector", "mcp__flowstudio__resolve_live_parameters" ], "ask": [ "mcp__flowstudio__report_bug", "mcp__flowstudio__update_store_flow", "mcp__flowstudio__trigger_live_flow", "mcp__flowstudio__resubmit_live_flow_run", "mcp__flowstudio__set_live_flow_state", "mcp__flowstudio__add_live_flow_to_solution", "mcp__flowstudio__test_live_connection", "mcp__flowstudio__create_live_connection" ], "deny": [ "mcp__flowstudio__cancel_live_flow_run", "mcp__flowstudio__update_live_flow" ] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__flowstudio__trigger_live_flow`: untrusted-input - `mcp__flowstudio__resubmit_live_flow_run`: untrusted-input - `mcp__flowstudio__resolve_live_parameters`: private-data ## Remote posture What an anonymous client saw at the remote endpoint, last 2026-10-22T15:03:15.832Z, unchanged since 2026-10-22T15:03:15.832Z.
