Discover Available Connectors

Call the list_connectors tool to retrieve all connectors.
  • Optionally filter by category: communication, crm, marketing, storage, etc.
  • The response includes connector IDs and descriptive names.
  • Use these IDs when calling other tools.

​
Inspect Resources and Actions

Use get_connector_resources to discover what a connector supports:
  • Pass the connectorId (e.g., slack, hubspot).
  • The server returns supported resources and actions.
Use get_action_details to retrieve:
  • Required and optional parameters.
  • Descriptions, data types, and sample values.

​
Execute an Action

To invoke an action, call execute_action with:
  • connectorId: Which platform to use (e.g., slack).
  • actionId: Action identifier (e.g., chat_postMessage).
  • parameters: JSON object containing input values (e.g., channel ID, message text).
  • credentialId (optional): Specify which credential to use if multiple exist.
The MCP server forwards the request and returns the platform’s response. Example: Slack MCP lets assistants read messages, post replies, search conversations, and list users or channels.

​
Manage Credentials

Most connectors require credentials (OAuth or API keys):
  • Use create_credential to initiate an OAuth flow.
    • Include connectorId, authenticationType, and redirectUri.
  • For key-based auth, include fields directly in the fields object.
  • Call get_credentials to list existing credentials.
  • Use get_credential_metadata to check supported auth methods and required fields.
