Build & Deploy Power Automate Flows with FlowStudio MCP
Step-by-step guide for constructing and deploying Power Automate cloud flows programmatically through the FlowStudio MCP server.
Prerequisite: A FlowStudio MCP server must be reachable with a valid JWT.

Source of Truth
Always call
tools/listfirst to confirm available tool names and their parameter schemas. Tool names and parameters may change between server versions. This skill covers response shapes, behavioral notes, and build patterns — thingstools/listcannot tell you. If this document disagrees withtools/listor a real API response, the API wins.
Python Helper
import json, urllib.request
MCP_URL = "https://mcp.flowstudio.app/mcp"
MCP_TOKEN = "<YOUR_JWT_TOKEN>"
def mcp(tool, **kwargs):
payload = json.dumps({"jsonrpc": "2.0", "id": 1, "method": "tools/call",
"params": {"name": tool, "arguments": kwargs}}).encode()
req = urllib.request.Request(MCP_URL, data=payload,
headers={"x-api-key": MCP_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'])}")
return json.loads(raw["result"]["content"][0]["text"])
ENV = "<environment-id>" # e.g. Default-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
Step 1 — Safety Check: Does the Flow Already Exist?
Always look before you build to avoid duplicates:
results = mcp("list_live_flows", environmentName=ENV)
# list_live_flows returns { "flows": [...] }
matches = [f for f in results["flows"]
if "My New Flow".lower() in f["displayName"].lower()]
if len(matches) > 0:
# Flow exists — modify rather than create
FLOW_ID = matches[0]["id"] # plain UUID from list_live_flows
print(f"Existing flow: {FLOW_ID}")
defn = mcp("get_live_flow", environmentName=ENV, flowName=FLOW_ID)
else:
print("Flow not found — building from scratch")
FLOW_ID = None
Step 2 — Obtain Connection References
Every connector action needs a connectionName that points to a key in the
flow's connectionReferences map. That key links to an authenticated connection
in the environment.
MANDATORY: You MUST call
list_live_connectionsfirst — do NOT ask the user for connection names or GUIDs. The API returns the exact values you need. Only prompt the user if the API confirms that required connections are missing.
2a — Always call list_live_connections first
conns = mcp("list_live_connections", environmentName=ENV)
# Filter to connected (authenticated) connections only
active = [c for c in conns["connections"]
if c["statuses"][0]["status"] == "Connected"]
# Build a lookup: connectorName → connectionName (id)
conn_map = {}
for c in active:
conn_map[c["connectorName"]] = c["id"]
print(f"Found {len(active)} active connections")
print("Available connectors:", list(conn_map.keys()))
2b — Determine which connectors the flow needs
Based on the flow you are building, identify which connectors are required. Common connector API names:
| Connector | API name |
|---|---|
| SharePoint | shared_sharepointonline |
| Outlook / Office 365 | shared_office365 |
| Teams | shared_teams |
| Approvals | shared_approvals |
| OneDrive for Business | shared_onedriveforbusiness |
| Excel Online (Business) | shared_excelonlinebusiness |
| Dataverse | shared_commondataserviceforapps |
| Microsoft Forms | shared_microsoftforms |
Flows that need NO connections (e.g. Recurrence + Compose + HTTP only) can skip the rest of Step 2 — omit
connectionReferencesfrom the deploy call.
2c — If connections are missing, guide the user
connectors_needed = ["shared_sharepointonline", "shared_office365"] # adjust per flow
missing = [c for c in connectors_needed if c not in conn_map]
if not missing:
print("✅ All required connections are available — proceeding to build")
else:
# ── STOP: connections must be created interactively ──
# Connections require OAuth consent in a browser — no API can create them.
print("⚠️ The following connectors have no active connection in this environment:")
for c in missing:
friendly = c.replace("shared_", "").replace("onlinebusiness", " Online (Business)")
print(f" • {friendly} (API name: {c})")
print()
print("Please create the missing connections:")
print(" 1. Open https://make.powerautomate.com/connections")
print(" 2. Select the correct environment from the top-right picker")
print(" 3. Click '+ New connection' for each missing connector listed above")
print(" 4. Sign in and authorize when prompted")
print(" 5. Tell me when done — I will re-check and continue building")
# DO NOT proceed to Step 3 until the user confirms.
# After user confirms, re-run Step 2a to refresh conn_map.
2d — Build the connectionReferences block
Only execute this after 2c confirms no missing connectors:
connection_references = {}
for connector in connectors_needed:
connection_references[connector] = {
"connectionName": conn_map[connector], # the GUID from list_live_connections
"source": "Invoker",
"id": f"/providers/Microsoft.PowerApps/apis/{connector}"
}
IMPORTANT —
host.connectionNamein actions: When building actions in Step 3, sethost.connectionNameto the key from this map (e.g.shared_teams), NOT the connection GUID. The GUID only goes inside theconnectionReferencesentry. The engine matches the action'shost.connectionNameto the key to find the right connection.
Alternative — if you already have a flow using the same connectors, you can extract
connectionReferencesfrom its definition:ref_flow = mcp("get_live_flow", environmentName=ENV, flowName="<existing-flow-id>") connection_references = ref_flow["properties"]["connectionReferences"]
See the flowstudio-power-automate-mcp skill's connection-references.md reference
for the full connection reference structure.
Step 3 — Build the Flow Definition
Construct the definition object. See flow-schema.md for the full schema and these action pattern references for copy-paste templates:
- action-patterns-core.md — Variables, control flow, expressions
- action-patterns-data.md — Array transforms, HTTP, parsing
- action-patterns-connectors.md — SharePoint, Outlook, Teams, Approvals
definition = {
"$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
"contentVersion": "1.0.0.0",
"triggers": { ... }, # see trigger-types.md / build-patterns.md
"actions": { ... } # see ACTION-PATTERNS-*.md / build-patterns.md
}
See build-patterns.md for complete, ready-to-use flow definitions covering Recurrence+SharePoint+Teams, HTTP triggers, and more.
Step 4 — Deploy (Create or Update)
update_live_flow handles both creation and updates in a single tool.
Create a new flow (no existing flow)
Omit flowName — the server generates a new GUID and creates via PUT:
result = mcp("update_live_flow",
environmentName=ENV,
# flowName omitted → creates a new flow
definition=definition,
connectionReferences=connection_references,
displayName="Overdue Invoice Notifications",
description="Weekly SharePoint → Teams notification flow, built by agent"
)
if result.get("error") is not None:
print("Create failed:", result["error"])
else:
# Capture the new flow ID for subsequent steps
FLOW_ID = result["created"]
print(f"✅ Flow created: {FLOW_ID}")
Update an existing flow
Provide flowName to PATCH:
result = mcp("update_live_flow",
environmentName=ENV,
flowName=FLOW_ID,
definition=definition,
connectionReferences=connection_references,
displayName="My Updated Flow",
description="Updated by agent on " + __import__('datetime').datetime.utcnow().isoformat()
)
if result.get("error") is not None:
print("Update failed:", result["error"])
else:
print("Update succeeded:", result)
⚠️
update_live_flowalways returns anerrorkey.null(PythonNone) means success — do not treat the presence of the key as failure.⚠️
descriptionis required for both create and update.
Common deployment errors
| Error message (contains) | Cause | Fix |
|---|---|---|
missing from connectionReferences |
An action's host.connectionName references a key that doesn't exist in the connectionReferences map |
Ensure host.connectionName uses the key from connectionReferences (e.g. shared_teams), not the raw GUID |
ConnectionAuthorizationFailed / 403 |
The connection GUID belongs to another user or is not authorized | Re-run Step 2a and use a connection owned by the current x-api-key user |
InvalidTemplate / InvalidDefinition |
Syntax error in the definition JSON | Check runAfter chains, expression syntax, and action type spelling |
ConnectionNotConfigured |
A connector action exists but the connection GUID is invalid or expired | Re-check list_live_connections for a fresh GUID |
Step 5 — Verify the Deployment
check = mcp("get_live_flow", environmentName=ENV, flowName=FLOW_ID)
# Confirm state
print("State:", check["properties"]["state"]) # Should be "Started"
# If state is "Stopped", use set_live_flow_state — NOT update_live_flow
# mcp("set_live_flow_state", environmentName=ENV, flowName=FLOW_ID, state="Started")
# Confirm the action we added is there
acts = check["properties"]["definition"]["actions"]
print("Actions:", list(acts.keys()))
Step 6 — Test the Flow
MANDATORY: Before triggering any test run, ask the user for confirmation. Running a flow has real side effects — it may send emails, post Teams messages, write to SharePoint, start approvals, or call external APIs. Explain what the flow will do and wait for explicit approval before calling
trigger_live_floworresubmit_live_flow_run.
Updated flows (have prior runs) — ANY trigger type
Use
resubmit_live_flow_runfirst. It works for EVERY trigger type — Recurrence, SharePoint, connector webhooks, Button, and HTTP. It replays the original trigger payload. Do NOT ask the user to manually trigger the flow or wait for the next scheduled run.
runs = mcp("get_live_flow_runs", environmentName=ENV, flowName=FLOW_ID, top=1)
if runs:
# Works for Recurrence, SharePoint, connector triggers — not just HTTP
result = mcp("resubmit_live_flow_run",
environmentName=ENV, flowName=FLOW_ID, runName=runs[0]["name"])
print(result) # {"resubmitted": true, "triggerName": "..."}
HTTP-triggered flows — custom test payload
Only use trigger_live_flow when you need to send a different payload
than the original run. For verifying a fix, resubmit_live_flow_run is
better because it uses the exact data that caused the failure.
schema = mcp("get_live_flow_http_schema",
environmentName=ENV, flowName=FLOW_ID)
print("Expected body:", schema.get("requestSchema"))
result = mcp("trigger_live_flow",
environmentName=ENV, flowName=FLOW_ID,
body={"name": "Test", "value": 1})
print(f"Status: {result['responseStatus']}")
Brand-new non-HTTP flows (Recurrence, connector triggers, etc.)
A brand-new Recurrence or connector-triggered flow has no prior runs to resubmit and no HTTP endpoint to call. This is the ONLY scenario where you need the temporary HTTP trigger approach below. Deploy with a temporary HTTP trigger first, test the actions, then swap to the production trigger.
7a — Save the real trigger, deploy with a temporary HTTP trigger
# Save the production trigger you built in Step 3
production_trigger = definition["triggers"]
# Replace with a temporary HTTP trigger
definition["triggers"] = {
"manual": {
"type": "Request",
"kind": "Http",
"inputs": {
"schema": {}
}
}
}
# Deploy (create or update) with the temp trigger
result = mcp("update_live_flow",
environmentName=ENV,
flowName=FLOW_ID, # omit if creating new
definition=definition,
connectionReferences=connection_references,
displayName="Overdue Invoice Notifications",
description="Deployed with temp HTTP trigger for testing")
if result.get("error") is not None:
print("Deploy failed:", result["error"])
else:
if not FLOW_ID:
FLOW_ID = result["created"]
print(f"✅ Deployed with temp HTTP trigger: {FLOW_ID}")
7b — Fire the flow and check the result
# Trigger the flow
test = mcp("trigger_live_flow",
environmentName=ENV, flowName=FLOW_ID)
print(f"Trigger response status: {test['status']}")
# Wait for the run to complete
import time; time.sleep(15)
# Check the run result
runs = mcp("get_live_flow_runs",
environmentName=ENV, flowName=FLOW_ID, top=1)
run = runs[0]
print(f"Run {run['name']}: {run['status']}")
if run["status"] == "Failed":
err = mcp("get_live_flow_run_error",
environmentName=ENV, flowName=FLOW_ID, runName=run["name"])
root = err["failedActions"][-1]
print(f"Root cause: {root['actionName']} → {root.get('code')}")
# Debug and fix the definition before proceeding
# See flowstudio-power-automate-debug skill for full diagnosis workflow
7c — Swap to the production trigger
Once the test run succeeds, replace the temporary HTTP trigger with the real one:
# Restore the production trigger
definition["triggers"] = production_trigger
result = mcp("update_live_flow",
environmentName=ENV,
flowName=FLOW_ID,
definition=definition,
connectionReferences=connection_references,
description="Swapped to production trigger after successful test")
if result.get("error") is not None:
print("Trigger swap failed:", result["error"])
else:
print("✅ Production trigger deployed — flow is live")
Why this works: The trigger is just the entry point — the actions are identical regardless of how the flow starts. Testing via HTTP trigger exercises all the same Compose, SharePoint, Teams, etc. actions.
Connector triggers (e.g. "When an item is created in SharePoint"): If actions reference
triggerBody()ortriggerOutputs(), pass a representative test payload intrigger_live_flow'sbodyparameter that matches the shape the connector trigger would produce.
Gotchas
| Mistake | Consequence | Prevention |
|---|---|---|
Missing connectionReferences in deploy |
400 "Supply connectionReferences" | Always call list_live_connections first |
"operationOptions" missing on Foreach |
Parallel execution, race conditions on writes | Always add "Sequential" |
union(old_data, new_data) |
Old values override new (first-wins) | Use union(new_data, old_data) |
split() on potentially-null string |
InvalidTemplate crash |
Wrap with coalesce(field, '') |
Checking result["error"] exists |
Always present; true error is != null |
Use result.get("error") is not None |
| Flow deployed but state is "Stopped" | Flow won't run on schedule | Call set_live_flow_state with state: "Started" — do not use update_live_flow for state changes |
| Teams "Chat with Flow bot" recipient as object | 400 GraphUserDetailNotFound |
Use plain string with trailing semicolon (see below) |
Teams PostMessageToConversation — Recipient Formats
The body/recipient parameter format depends on the location value:
| Location | body/recipient format |
Example |
|---|---|---|
| Chat with Flow bot | Plain email string with trailing semicolon | "user@contoso.com;" |
| Channel | Object with groupId and channelId |
{"groupId": "...", "channelId": "..."} |
Common mistake: passing
{"to": "user@contoso.com"}for "Chat with Flow bot" returns a 400GraphUserDetailNotFounderror. The API expects a plain string.
