MCP Tools

The Baselayer MCP server exposes 17 tools. Each one calls the same service that backs the matching REST endpoint, so billing, sandbox behavior, permissions, and response shapes are identical across both surfaces. The linked API reference page for each tool documents the full response schema.

Tools come in pairs: a tool that starts work and a get_* tool that reads it back by id. The MCP Overview explains when your assistant needs to poll.

COMPLETED, FAILED, and CANCELLED are terminal. Anything else should be polled with the matching get_* tool.

Permissions

Tools check the same role permissions as the REST API. If your role lacks a permission the tool returns an error naming it, and an organization admin can grant it in the Console.
