MCP tools

Server: https://api.quorumcal.com/mcp (Streamable HTTP, stateless). Set it up in the MCP guide. A tool call runs the same route the REST API does, with your credential, so scopes, org limits and policies apply unchanged. Tool names are the CLI command with underscores.

Sessions start with the core toolset. Three meta tools reach the rest: list_toolsets, enable_toolset (returns a toolset’s tools and their schemas) and call_tool (runs any tool by name). Connect with /mcp?toolsets=links,polls or /mcp?toolsets=all to list more up front.
