--- name: flowstudio-power-automate-mcp description: >- Connect to and operate Power Automate cloud flows via a FlowStudio MCP server. Use when asked to: list flows, read a flow definition, check run history, inspect action outputs, resubmit a run, cancel a running flow, view connections, get a trigger URL, validate a definition, monitor flow health, or any task that requires talking to the Power Automate API through an MCP tool. Also use for Power Platform environment discovery and connection management. Requires a FlowStudio MCP subscription or compatible server — see https://mcp.flowstudio.app --- # Power Automate via FlowStudio MCP This skill lets AI agents read, monitor, and operate Microsoft Power Automate cloud flows programmatically through a **FlowStudio MCP server** — no browser, no UI, no manual steps. > **Requires:** A [FlowStudio](https://mcp.flowstudio.app) MCP subscription (or > compatible Power Automate MCP server). You will need: > - MCP endpoint: `https://mcp.flowstudio.app/mcp` (same for all subscribers) > - API key / JWT token (`x-api-key` header — NOT Bearer) > - Power Platform environment name (e.g. `Default-`) --- ## Source of Truth | Priority | Source | Covers | |----------|--------|--------| | 1 | **Real API response** | Always trust what the server actually returns | | 2 | **`tools/list`** | Tool names, parameter names, types, required flags | | 3 | **SKILL docs & reference files** | Response shapes, behavioral notes, workflow recipes | > **Start every new session with `tools/list`.** > It returns the authoritative, up-to-date schema for every tool — parameter names, > types, and required flags. The SKILL docs cover what `tools/list` cannot tell you: > response shapes, non-obvious behaviors, and end-to-end workflow patterns. > > If any documentation disagrees with `tools/list` or a real API response, > the API wins. --- ## Recommended Language: Python or Node.js All examples in this skill and the companion build / debug skills use **Python with `urllib.request`** (stdlib — no `pip install` needed). **Node.js** is an equally valid choice: `fetch` is built-in from Node 18+, JSON handling is native, and the async/await model maps cleanly onto the request-response pattern of MCP tool calls — making it a natural fit for teams already working in a JavaScript/TypeScript stack. | Language | Verdict | Notes | |---|---|---| | **Python** | ✅ Recommended | Clean JSON handling, no escaping issues, all skill examples use it | | **Node.js (≥ 18)** | ✅ Recommended | Native `fetch` + `JSON.stringify`/`JSON.parse`; async/await fits MCP call patterns well; no extra packages needed | | PowerShell | ⚠️ Avoid for flow operations | `ConvertTo-Json -Depth` silently truncates nested definitions; quoting and escaping break complex payloads. Acceptable for a quick `tools/list` discovery call but not for building or updating flows. | | cURL / Bash | ⚠️ Possible but fragile | Shell-escaping nested JSON is error-prone; no native JSON parser | > **TL;DR — use the Core MCP Helper (Python or Node.js) below.** Both handle > JSON-RPC framing, auth, and response parsing in a single reusable function. --- ## What You Can Do FlowStudio MCP has two access tiers. **FlowStudio for Teams** subscribers get both the fast Azure-table store (cached snapshot data + governance metadata) and full live Power Automate API access. **MCP-only subscribers** get the live tools — more than enough to build, debug, and operate flows. ### Live Tools — Available to All MCP Subscribers | Tool | What it does | |---|---| | `list_live_flows` | List flows in an environment directly from the PA API (always current) | | `list_live_environments` | List all Power Platform environments visible to the service account | | `list_live_connections` | List all connections in an environment from the PA API | | `get_live_flow` | Fetch the complete flow definition (triggers, actions, parameters) | | `get_live_flow_http_schema` | Inspect the JSON body schema and response schemas of an HTTP-triggered flow | | `get_live_flow_trigger_url` | Get the current signed callback URL for an HTTP-triggered flow | | `trigger_live_flow` | POST to an HTTP-triggered flow's callback URL (AAD auth handled automatically) | | `update_live_flow` | Create a new flow or patch an existing definition in one call | | `add_live_flow_to_solution` | Migrate a non-solution flow into a solution | | `get_live_flow_runs` | List recent run history with status, start/end times, and errors | | `get_live_flow_run_error` | Get structured error details (per-action) for a failed run | | `get_live_flow_run_action_outputs` | Inspect inputs/outputs of any action (or every foreach iteration) in a run | | `resubmit_live_flow_run` | Re-run a failed or cancelled run using its original trigger payload | | `cancel_live_flow_run` | Cancel a currently running flow execution | ### Store Tools — FlowStudio for Teams Subscribers Only These tools read from (and write to) the FlowStudio Azure table — a monitored snapshot of your tenant's flows enriched with governance metadata and run statistics. | Tool | What it does | |---|---| | `list_store_flows` | Search flows from the cache with governance flags, run failure rates, and owner metadata | | `get_store_flow` | Get full cached details for a single flow including run stats and governance fields | | `get_store_flow_trigger_url` | Get the trigger URL from the cache (instant, no PA API call) | | `get_store_flow_runs` | Cached run history for the last N days with duration and remediation hints | | `get_store_flow_errors` | Cached failed-only runs with failed action names and remediation hints | | `get_store_flow_summary` | Aggregated stats: success rate, failure count, avg/max duration | | `set_store_flow_state` | Start or stop a flow via the PA API and sync the result back to the store | | `update_store_flow` | Update governance metadata (description, tags, monitor flag, notification rules, business impact) | | `list_store_environments` | List all environments from the cache | | `list_store_makers` | List all makers (citizen developers) from the cache | | `get_store_maker` | Get a maker's flow/app counts and account status | | `list_store_power_apps` | List all Power Apps canvas apps from the cache | | `list_store_connections` | List all Power Platform connections from the cache | --- ## Which Tool Tier to Call First | Task | Tool | Notes | |---|---|---| | List flows | `list_live_flows` | Always current — calls PA API directly | | Read a definition | `get_live_flow` | Always fetched live — not cached | | Debug a failure | `get_live_flow_runs` → `get_live_flow_run_error` | Use live run data | > ⚠️ **`list_live_flows` returns a wrapper object** with a `flows` array — access via `result["flows"]`. > Store tools (`list_store_flows`, `get_store_flow`, etc.) are available to **FlowStudio for Teams** subscribers and provide cached governance metadata. Use live tools when in doubt — they work for all subscription tiers. --- ## Step 0 — Discover Available Tools Always start by calling `tools/list` to confirm the server is reachable and see exactly which tool names are available (names may vary by server version): ```python import json, urllib.request TOKEN = "" MCP = "https://mcp.flowstudio.app/mcp" def mcp_raw(method, params=None, cid=1): payload = {"jsonrpc": "2.0", "method": method, "id": cid} if params: payload["params"] = params req = urllib.request.Request(MCP, data=json.dumps(payload).encode(), headers={"x-api-key": TOKEN, "Content-Type": "application/json", "User-Agent": "FlowStudio-MCP/1.0"}) try: resp = urllib.request.urlopen(req, timeout=30) except urllib.error.HTTPError as e: raise RuntimeError(f"MCP HTTP {e.code} — check token and endpoint") from e return json.loads(resp.read()) raw = mcp_raw("tools/list") if "error" in raw: print("ERROR:", raw["error"]); raise SystemExit(1) for t in raw["result"]["tools"]: print(t["name"], "—", t["description"][:60]) ``` --- ## Core MCP Helper (Python) Use this helper throughout all subsequent operations: ```python import json, urllib.request TOKEN = "" MCP = "https://mcp.flowstudio.app/mcp" def mcp(tool, args, cid=1): payload = {"jsonrpc": "2.0", "method": "tools/call", "id": cid, "params": {"name": tool, "arguments": args}} req = urllib.request.Request(MCP, data=json.dumps(payload).encode(), headers={"x-api-key": TOKEN, "Content-Type": "application/json", "User-Agent": "FlowStudio-MCP/1.0"}) try: resp = urllib.request.urlopen(req, timeout=120) except urllib.error.HTTPError as e: body = e.read().decode("utf-8", errors="replace") raise RuntimeError(f"MCP HTTP {e.code}: {body[:200]}") from e raw = json.loads(resp.read()) if "error" in raw: raise RuntimeError(f"MCP error: {json.dumps(raw['error'])}") text = raw["result"]["content"][0]["text"] return json.loads(text) ``` > **Common auth errors:** > - HTTP 401/403 → token is missing, expired, or malformed. Get a fresh JWT from [mcp.flowstudio.app](https://mcp.flowstudio.app). > - HTTP 400 → malformed JSON-RPC payload. Check `Content-Type: application/json` and body structure. > - `MCP error: {"code": -32602, ...}` → wrong or missing tool arguments. --- ## Core MCP Helper (Node.js) Equivalent helper for Node.js 18+ (built-in `fetch` — no packages required): ```js const TOKEN = ""; const MCP = "https://mcp.flowstudio.app/mcp"; async function mcp(tool, args, cid = 1) { const payload = { jsonrpc: "2.0", method: "tools/call", id: cid, params: { name: tool, arguments: args }, }; const res = await fetch(MCP, { method: "POST", headers: { "x-api-key": TOKEN, "Content-Type": "application/json", "User-Agent": "FlowStudio-MCP/1.0", }, body: JSON.stringify(payload), }); if (!res.ok) { const body = await res.text(); throw new Error(`MCP HTTP ${res.status}: ${body.slice(0, 200)}`); } const raw = await res.json(); if (raw.error) throw new Error(`MCP error: ${JSON.stringify(raw.error)}`); return JSON.parse(raw.result.content[0].text); } ``` > Requires Node.js 18+. For older Node, replace `fetch` with `https.request` > from the stdlib or install `node-fetch`. --- ## List Flows ```python ENV = "Default-" result = mcp("list_live_flows", {"environmentName": ENV}) # Returns wrapper object: # {"mode": "owner", "flows": [{"id": "0757041a-...", "displayName": "My Flow", # "state": "Started", "triggerType": "Request", ...}], "totalCount": 42, "error": null} for f in result["flows"]: FLOW_ID = f["id"] # plain UUID — use directly as flowName print(FLOW_ID, "|", f["displayName"], "|", f["state"]) ``` --- ## Read a Flow Definition ```python FLOW = "" flow = mcp("get_live_flow", {"environmentName": ENV, "flowName": FLOW}) # Display name and state print(flow["properties"]["displayName"]) print(flow["properties"]["state"]) # List all action names actions = flow["properties"]["definition"]["actions"] print("Actions:", list(actions.keys())) # Inspect one action's expression print(actions["Compose_Filter"]["inputs"]) ``` --- ## Check Run History ```python # Most recent runs (newest first) runs = mcp("get_live_flow_runs", {"environmentName": ENV, "flowName": FLOW, "top": 5}) # Returns direct array: # [{"name": "08584296068667933411438594643CU15", # "status": "Failed", # "startTime": "2026-02-25T06:13:38.6910688Z", # "endTime": "2026-02-25T06:15:24.1995008Z", # "triggerName": "manual", # "error": {"code": "ActionFailed", "message": "An action failed..."}}, # {"name": "08584296028664130474944675379CU26", # "status": "Succeeded", "error": null, ...}] for r in runs: print(r["name"], r["status"]) # Get the name of the first failed run run_id = next((r["name"] for r in runs if r["status"] == "Failed"), None) ``` --- ## Inspect an Action's Output ```python run_id = runs[0]["name"] out = mcp("get_live_flow_run_action_outputs", { "environmentName": ENV, "flowName": FLOW, "runName": run_id, "actionName": "Get_Customer_Record" # exact action name from the definition }) print(json.dumps(out, indent=2)) ``` --- ## Get a Run's Error ```python err = mcp("get_live_flow_run_error", { "environmentName": ENV, "flowName": FLOW, "runName": run_id }) # Returns: # {"runName": "08584296068...", # "failedActions": [ # {"actionName": "HTTP_find_AD_User_by_Name", "status": "Failed", # "code": "NotSpecified", "startTime": "...", "endTime": "..."}, # {"actionName": "Scope_prepare_workers", "status": "Failed", # "error": {"code": "ActionFailed", "message": "An action failed..."}} # ], # "allActions": [ # {"actionName": "Apply_to_each", "status": "Skipped"}, # {"actionName": "Compose_WeekEnd", "status": "Succeeded"}, # ... # ]} # The ROOT cause is usually the deepest entry in failedActions: root = err["failedActions"][-1] print(f"Root failure: {root['actionName']} → {root['code']}") ``` --- ## Resubmit a Run ```python result = mcp("resubmit_live_flow_run", { "environmentName": ENV, "flowName": FLOW, "runName": run_id }) print(result) # {"resubmitted": true, "triggerName": "..."} ``` --- ## Cancel a Running Run ```python mcp("cancel_live_flow_run", { "environmentName": ENV, "flowName": FLOW, "runName": run_id }) ``` > ⚠️ **Do NOT cancel a run that shows `Running` because it is waiting for an > adaptive card response.** That status is normal — the flow is paused waiting > for a human to respond in Teams. Cancelling it will discard the pending card. --- ## Full Round-Trip Example — Debug and Fix a Failing Flow ```python # ── 1.
