Power Automate MCP Server by Flow Studio

Describe connector

describe_live_connector
Read-only

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.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
topNoMax operations to return in connector summary mode, or max top search results to show in cross-connector search. Default 250 for summary, 10 for search display.
typeNoOperation usage to include in summary mode. Default Action.
depthNosummary (default): compact operation catalog. full: raw OpenAPI metadata.
searchNoOptional operation search text. With connectorName, filters that connector summary. Without connectorName, searches operations across connectors.
apiNameNoAlias for connectorName.
variantNoWhen an operation has multiple authored variants (e.g. shared_teams/PostMessageToConversation has channel/groupchat/flowbot_chat), pass a specific variantKey to get that variant's hint and exampleDefinition. Omit to receive a hint listing the available variants.
operationIdNoOptional operation ID to describe with expanded inputs and outputs.
connectorNameNoConnector logical name, for example shared_teams. Either connectorName/apiName is required, unless search is provided for cross-connector operation search.
environmentNameYesName of the Power Platform environment.
