MCP tool reference - SendPilot API

This reference is generated from the shipped tool catalog. See the setup guide, client instructions, and approvals and retries. Workspace access and current permissions can reduce the tools exposed to your connection. 22 tools. The root API-key URL https://mcp.sendpilot.ai and its /mcp alias serve all toolsets; /mcp/readonly only read tools; /mcp/{toolset} one toolset. OAuth uses the exact connection URL from the dashboard (new URLs use /connections/<uuid>). Scopes and workspace entitlement determine which tools are available.
