- jz.bm.mcp-links on the token twins and the management API: under MCP,
url and *_url strings starting with a single / get the app base
- material answers under MCP leave the body out unless include_body,
marking it with body_omitted; write answers never echo it
- jz.bm.manage keys a dispatched call by user
- bm_materials and bm_material student tools
Plain HTTP answers are unchanged.
The management API could only upsert a material on its title and course,
so a renamed note became a second material. PUT /materials/{id} applies the
same body to one material (422 when the new title and course belong to
another one), GET /materials/{id} shows a draft or published material with
its public files, and the upsert, update and validation share one path.
The README documents the management API.
