FlowStudio MCP — Action Types Reference
Compact lookup for recognising action types returned by get_live_flow.
Use this to read and understand existing flow definitions.
For full copy-paste construction patterns, see the
flowstudio-power-automate-buildskill.
How to Read a Flow Definition
Every action has "type", "runAfter", and "inputs". The runAfter object
declares dependencies: {"Previous": ["Succeeded"]}. Valid statuses:
Succeeded, Failed, Skipped, TimedOut.
Action Type Quick Reference
| Type | Purpose | Key fields to inspect | Output reference |
|---|---|---|---|
Compose |
Store/transform a value | inputs (any expression) |
outputs('Name') |
InitializeVariable |
Declare a variable | inputs.variables[].{name, type, value} |
variables('name') |
SetVariable |
Update a variable | inputs.{name, value} |
variables('name') |
IncrementVariable |
Increment a numeric variable | inputs.{name, value} |
variables('name') |
AppendToArrayVariable |
Push to an array variable | inputs.{name, value} |
variables('name') |
If |
Conditional branch | expression.and/or, actions, else.actions |
— |
Switch |
Multi-way branch | expression, cases.{case, actions}, default |
— |
Foreach |
Loop over array | foreach, actions, operationOptions |
item() / items('Name') |
Until |
Loop until condition | expression, limit.{count, timeout}, actions |
— |
Wait |
Delay | inputs.interval.{count, unit} |
— |
Scope |
Group / try-catch | actions (nested action map) |
result('Name') |
Terminate |
End run | inputs.{runStatus, runError} |
— |
OpenApiConnection |
Connector call (SP, Outlook, Teams…) | inputs.host.{apiId, connectionName, operationId}, inputs.parameters |
outputs('Name')?['body/...'] |
OpenApiConnectionWebhook |
Webhook wait (approvals, adaptive cards) | same as above | body('Name')?['...'] |
Http |
External HTTP call | inputs.{method, uri, headers, body} |
outputs('Name')?['body'] |
Response |
Return to HTTP caller | inputs.{statusCode, headers, body} |
— |
Query |
Filter array | inputs.{from, where} |
body('Name') (filtered array) |
Select |
Reshape/project array | inputs.{from, select} |
body('Name') (projected array) |
Table |
Array → CSV/HTML string | inputs.{from, format, columns} |
body('Name') (string) |
ParseJson |
Parse JSON with schema | inputs.{content, schema} |
body('Name')?['field'] |
Expression |
Built-in function (e.g. ConvertTimeZone) | kind, inputs |
body('Name') |
Connector Identification
When you see type: OpenApiConnection, identify the connector from host.apiId:
| apiId suffix | Connector |
|---|---|
shared_sharepointonline |
SharePoint |
shared_office365 |
Outlook / Office 365 |
shared_teams |
Microsoft Teams |
shared_approvals |
Approvals |
shared_office365users |
Office 365 Users |
shared_flowmanagement |
Flow Management |
The operationId tells you the specific operation (e.g. GetItems, SendEmailV2,
PostMessageToConversation). The connectionName maps to a GUID in
properties.connectionReferences.
Common Expressions (Reading Cheat Sheet)
| Expression | Meaning |
|---|---|
@outputs('X')?['body/value'] |
Array result from connector action X |
@body('X') |
Direct body of action X (Query, Select, ParseJson) |
@item()?['Field'] |
Current loop item's field |
@triggerBody()?['Field'] |
Trigger payload field |
@variables('name') |
Variable value |
@coalesce(a, b) |
First non-null of a, b |
@first(array) |
First element (null if empty) |
@length(array) |
Array count |
@empty(value) |
True if null/empty string/empty array |
@union(a, b) |
Merge arrays — first wins on duplicates |
@result('Scope') |
Array of action outcomes inside a Scope |
