MCP Tools Reference

Ceum exposes a Model Context Protocol (MCP) server so external tools — Claude Desktop, Cursor, custom agents — can read and write your workspace through token-scoped, audited tool calls. This section catalogs every tool, grouped by the part of the workspace it operates on.

These articles are generated from the live set of tools — what you read here is exactly what an agent sees when it lists the tools available over MCP, so the descriptions and parameters always match the server.

How to use this reference

• Browsing by category. Each child article lists one category's tools, with a one-line summary table and per-tool parameter tables. Open the category that matches the entity you want to touch.
• Looking up a single tool. Tool names follow verb_entity (e.g. list_tasks, create_subscription). Headings on each category page anchor to the tool name, so a deep link like /kb/mcp-tools-tasks#create-task jumps straight to it.
• Understanding side effects. Every tool's mutating flag and audit-log behavior is documented in MCP — Overview. Mutations are recorded against the calling token; reads are not.

Categories
