FlowStudio MCP — Tool Response Catalog
Response shapes and behavioral notes for the FlowStudio Power Automate MCP server.
For tool names and parameters: Prefer
list_skillsandtool_search. They return focused, up-to-date schemas without loading every MCP tool at once. Usetools/listonly as a low-level fallback when the meta-tools are not available. This document covers what tool schemas do NOT tell you: response shapes and non-obvious behaviors discovered through real usage.
Source of Truth
| Priority | Source | Covers |
|---|---|---|
| 1 | Real API response | Always trust what the server actually returns |
| 2 | list_skills / tool_search |
Tool names, parameter names, types, required flags |
| 3 | This document | Response shapes, behavioral notes, gotchas |
If this document disagrees with
tool_search,tools/list, or real API behavior, the API wins. Update this document accordingly.
Environment & Tenant Discovery
list_live_environments
Response: direct array of environments.
[

Use the
idvalue asenvironmentNamein all other tools.
list_store_environments
Same shape as list_live_environments but read from cache (faster).
Connection Discovery
list_live_connections
Response: wrapper object with connections array.
{
"connections": [
{

Key field:
idis theconnectionNamevalue used inconnectionReferences.Key field:
connectorNamemaps to apiId:"/providers/Microsoft.PowerApps/apis/" + connectorNameFilter by status: prefer
overallStatus == "Connected"when present; otherwise checkstatuses[0].status == "Connected".For build workflows, pass
environmentNameto avoid using a connection from the wrong environment. Omit it only when intentionally inventorying connections across all environments.Pass
search=<connector or account>to narrow output and receiveconnectionReferenceTemplateplushostTemplatevalues that can be copied directly intoupdate_live_flow.
list_store_connections
Same connection data from cache.
Flow Discovery & Listing
list_live_flows
Response: wrapper object with flows array.
{
"mode": "owner",
"flows": [
{
"id": "0757041a-8ef2-cf74-ef06-06881916f371",

Access via
result["flows"].idis a plain UUID --- use directly asflowName.
modeindicates the access scope used ("owner"or"admin").Parameters added in newer server versions:
search: filter by display name server-side.mode:ownerfor flows owned by the MCP identity;adminfor all flows visible to an admin account.timeoutSeconds: return partial results withnextLinkinstead of waiting on very large environments.continuationUrl: pass the previousnextLinkto continue the same query.
list_store_flows
Response: direct array (no wrapper).
[

"createdBy": "user@contoso.com"
}
runPeriodDurationAverage/runPeriodDurationMaxare in milliseconds (divide by 1000).runErroris a JSON string --- parse withjson.loads().
Flow Definition (Live API)
get_live_flow
Response: full flow definition from PA API.
{
"name": "<flow-guid>",
"properties": {
"displayName": "My Flow",
"state": "Started",
"definition": {
"triggers": { "..." },
"actions": { "..." },
"parameters": { "..." }
},
"connectionReferences": { "..." }
}
}
update_live_flow
Create mode: Omit flowName --- creates a new flow. definition and displayName required.
Update mode: Provide flowName --- PATCHes existing flow.
Response:
{
"created": false,
"flowKey": "<environmentId>.<flowId>",
"updated": ["definition", "connectionReferences"],
"displayName": "My Flow",
"state": "Started",
"definition": { "...full definition..." },
"error": null
}
erroris always present but may benull. Checkresult.get("error") is not None.On create:
createdis the new flow GUID (string). On update:createdisfalse.Required fields can vary by server version. Use
tool_searchwithselect:update_live_flowbefore creating or patching a flow; if a description is required, include either the new description or the existing one fromget_live_flow.The flow description is part of the workflow definition (
definition.description), not a top-level tool argument in current schemas.
add_live_flow_to_solution
Migrates a non-solution flow into a solution. Returns error if already in a solution.
Use this after creating a Copilot Studio Skills-triggered flow that must be
discoverable as an agent tool. Pass solutionId for the target solution. If the
server supports omitting solutionId, it uses the environment's default solution;
prefer an explicit unmanaged solution for production ALM.
This tool changes solution membership only. It does not validate the trigger schema, publish a Copilot Studio agent, or prove that the flow is callable by the agent.
Connector Operation Discovery
describe_live_connector
Describes a connector/API and its operations. Use it before creating connector actions instead of guessing operation JSON.
Common modes:
| Call shape | Use |
|---|---|
search="send email" without connectorName |
Search operations across connectors |
connectorName="shared_sharepointonline" |
Compact operation catalog for one connector |
operationId="GetItems" |
Expanded schema for one operation |
variant="flowbot_chat" |
Authored example for one operation variant |
The operation detail can include:
hint: authored guidance from the connector hints table.exampleDefinition: copy-ready action/trigger shape when available.- Dynamic metadata with
nextTool=get_live_dynamic_optionsornextTool=get_live_dynamic_properties.
get_live_dynamic_options
Resolves live dropdown/list options for connector parameters. Use this for
IDs selected from lists, such as SharePoint sites/lists, Teams teams/channels,
or other x-ms-dynamic-list / x-ms-dynamic-values parameters.
Pass the dynamicMetadata object returned by describe_live_connector, the
connection id from list_live_connections, and any already-resolved dependent
parameters.
get_live_dynamic_properties
Resolves live schema/field properties for connector parameters. Use this for dynamic field sets such as SharePoint list item columns after the site and list are known.
Useful parameters:
parameters: dependent values, for example{ "dataset": "<site-url>", "table": "<list-id>" }.propertyName: request one field after inspecting the compact response.includeRaw: include raw connector schema only when needed; it can be large.
Run History & Monitoring
get_live_flow_runs
Response: direct array of runs (newest first).
[{
"name": "<run-id>",
"status": "Succeeded|Failed|Running|Cancelled",
"startTime": "2026-02-25T06:13:38Z",
"endTime": "2026-02-25T06:14:02Z",
"triggerName": "Recurrence",
"error": null
}]
topdefaults to 30 and auto-paginates for higher values. Settop: 300for 24-hour coverage on flows running every 5 minutes.Run ID field is
name(notrunName). Use this value as therunNameparameter in other tools.
get_live_flow_run_error
Response: structured error breakdown for a failed run.
{
"runName": "08584296068667933411438594643CU15",
"failedActions": [
{
"actionName": "Apply_to_each_prepare_workers",
"status": "Failed",
"error": {"code": "ActionFailed", "message": "An action failed."},
"code": "ActionFailed",
"startTime": "2026-02-25T06:13:52Z",
"endTime": "2026-02-25T06:15:24Z"
},
{
"actionName": "HTTP_find_AD_User_by_Name",
"status": "Failed",
"code": "NotSpecified",
"startTime": "2026-02-25T06:14:01Z",
"endTime": "2026-02-25T06:14:05Z"
}
],
"allActions": [
{"actionName": "Apply_to_each", "status": "Skipped"},
{"actionName": "Compose_WeekEnd", "status": "Succeeded"},
{"actionName": "HTTP_find_AD_User_by_Name", "status": "Failed"}
]
}
failedActionsis ordered outer-to-inner --- the last entry is the root cause. UsefailedActions[-1]["actionName"]as the starting point for diagnosis.
get_live_flow_run_action_outputs
Response: array of action detail objects.
[
{
"actionName": "Compose_WeekEnd_now",
"status": "Succeeded",
"startTime": "2026-02-25T06:13:52Z",
"endTime": "2026-02-25T06:13:52Z",
"error": null,
"inputs": "Mon, 25 Feb 2026 06:13:52 GMT",
"outputs": "Mon, 25 Feb 2026 06:13:52 GMT"
}
]
actionNameis optional: omit it to return top-level actions in the run. Provide it for a specific action. If that action runs inside a foreach, the tool can return every repetition of that action across iterations; passiterationIndexto pin to one zero-based iteration.Outputs can be very large (50 MB+) for bulk-data actions. Use 120s+ timeout.
Run Control
resubmit_live_flow_run
Response: { flowKey, resubmitted: true, runName, triggerName }
cancel_live_flow_run
Cancels a Running flow run.
Do NOT cancel runs waiting for an adaptive card response --- status
Runningis normal while a Teams card is awaiting user input.
HTTP Trigger Tools
get_live_flow_http_schema
Deprecated. Prefer get_live_flow and inspect the Request trigger's
inputs.schema plus any Response actions directly from the definition.
Response keys:
flowKey - Flow GUID
displayName - Flow display name
triggerName - Trigger action name (e.g. "manual")
triggerType - Trigger type (e.g. "Request")
triggerKind - Trigger kind (e.g. "Http")
requestMethod - HTTP method (e.g. "POST")
relativePath - Relative path configured on the trigger (if any)
requestSchema - JSON schema the trigger expects as POST body
requestHeaders - Headers the trigger expects
responseSchemas - Array of JSON schemas defined on Response action(s)
responseSchemaCount - Number of Response actions that define output schemas
The request body schema is in
requestSchema(nottriggerSchema).
get_live_flow_trigger_url
Deprecated. Prefer trigger_live_flow when you need to run a flow; it fetches the
callback URL internally for HTTP triggers and uses the connector runtime for
Button and PowerApps triggers, which have no callback URL.
Returns the signed callback URL for HTTP-triggered flows. Response includes
flowKey, triggerName, triggerType, triggerKind, triggerMethod, triggerUrl.
trigger_live_flow
Response keys: flowKey, triggerName, triggerKind, invocation, triggerUrl,
requiresAadAuth, authType, responseStatus, responseBody, runName, and
warning when a required trigger input was not supplied.
Works for
Requesttriggers: HTTP request, Button, and PowerApps. Returns an error for Recurrence and connector triggers:"only HTTP Request triggers can be invoked via this tool".HTTP triggers go through the signed callback URL (
invocation: callbackUrl). Button and PowerApps triggers have no callback URL; with abodythey run through the Power Platform connector runtime (connectorFlowTokenorconnectorApihubToken), which is the only route that delivers the inputs. With no body they use the cheaper direct run (directRun).
runNameis returned only for connector-runtime runs. Otherwise look the run up withget_live_flow_runs.Power Automate does not enforce a trigger's
requiredlist. A missing input still starts the run with a null value;warningnames the missing keys and the body shape to retry with.Browser-extension keys cannot reach the connector runtime, so Button and PowerApps triggers run only with an empty body over that key type. The error lists the alternatives (resubmit a past run, default the inputs inside the flow with
coalesce(), or use a standard key).
responseStatus+responseBodycontain the flow's Response action output. AAD-authenticated triggers are handled automatically.Content type:
bodyis sent asapplication/json, sotriggerBody()and the trigger schema see the object you passed. Verified 2026-08-27 on server 1.2.43 against Button, PowerAppV2, and Skills triggers withrequiredschemas.
Flow State Management
set_live_flow_state
Start or stop a Power Automate flow via the live PA API. Does not require a Power Clarity workspace — works for any flow the impersonated account can access. Reads the current state first and only issues the start/stop call if a change is actually needed.
Parameters: environmentName, flowName, state ("Started" | "Stopped") — all required.
Response:
{
"flowName": "6321ab25-7eb0-42df-b977-e97d34bcb272",
"environmentName": "Default-26e65220-...",
"requestedState": "Started",
"actualState": "Started"
}
Use this tool — not
update_live_flow— to start or stop a flow.update_live_flowonly changes displayName/definition; the PA API ignores state passed through that endpoint.
set_store_flow_state
Start or stop a flow via the live PA API and persist the updated state back
to the Power Clarity cache. Same parameters as set_live_flow_state but requires
a Power Clarity workspace.
Response (different shape from set_live_flow_state):
{
"flowKey": "<environmentId>.<flowId>",
"requestedState": "Stopped",
"currentState": "Stopped",
"flow": { /* full gFlows record, same shape as get_store_flow */ }
}
Prefer
set_live_flow_statewhen you only need to toggle state — it's simpler and has no subscription requirement.Use
set_store_flow_statewhen you need the cache updated immediately (without waiting for the next daily scan) AND want the full updated governance record back in the same call — useful for workflows that stop a flow and immediately tag or inspect it.
Store Tools --- FlowStudio for Teams Only
get_store_flow_summary
Response: aggregated run statistics.
{
"totalRuns": 100,
"failRuns": 10,
"failRate": 0.1,
"averageDurationSeconds": 29.4,
"maxDurationSeconds": 158.9,
"firstFailRunRemediation": "<hint or null>"
}
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_trigger_url
Trigger URL from cache (instant, no PA API call).
update_store_flow
Update governance metadata (description, tags, monitor flag, notification rules, business impact).
list_store_makers / get_store_maker
Maker (citizen developer) discovery and detail.
list_store_power_apps
List all Power Apps canvas apps from the cache.
Behavioral Notes
Non-obvious behaviors discovered through real API usage. These are things tool schemas cannot tell you.
get_live_flow_run_action_outputs
actionNameis optional: omit to get top-level actions, provide to get one action. For actions inside foreach loops, a named action may return multiple repetitions; useiterationIndexto pin to one iteration.- Outputs can be 50 MB+ for bulk-data actions --- always use 120s+ timeout.
update_live_flow
- Required fields can vary by server version; confirm with
tool_search(select:update_live_flow) before create/update. Ifdescriptionis required, preserve the existing description when patching. errorkey is always present in response ---nullmeans success. Do NOT checkif "error" in result; checkresult.get("error") is not None.- On create,
created= new flow GUID (string). On update,created=false. - Cannot change flow state. Only updates displayName, definition, and
connectionReferences. Use
set_live_flow_stateto start/stop a flow.
trigger_live_flow
- Works for HTTP, Button, and PowerApps triggers. Returns error for Recurrence, connector, and other trigger types.
- Pass trigger inputs as
body. Awarningin the result means a required input was missing and the run started with it null. - AAD-authenticated triggers are handled automatically (impersonated Bearer token).
get_live_flow_runs
topdefaults to 30 with automatic pagination for higher values.- Run ID field is
name, notrunName. Use this value asrunNamein other tools. - Runs are returned newest-first.
Teams PostMessageToConversation (via update_live_flow)
- "Chat with Flow bot":
body/recipient="user@domain.com;"(string with trailing semicolon). - "Channel":
body/recipient={"groupId": "...", "channelId": "..."}(object). poster:"Flow bot"for Workflows bot identity,"User"for user identity.
list_live_connections
- For build workflows, pass
environmentName; omitting it inventories connections across environments. - Use
search=<connector/account>to get smaller output and paste-readyconnectionReferenceTemplate/hostTemplatevalues. idis the value you need forconnectionNameinconnectionReferences.connectorNamemaps to apiId:"/providers/Microsoft.PowerApps/apis/" + connectorName.
