Add AttachmentService_CreateAttachment to the curated MCP allowlist so
agents can upload files (inline base64 content) alongside memos, closing
the gap where the MCP server could list/get/delete attachments but not
create them.
Closes#6057
Make the OpenAPI-driven MCP surface more usable by agents, following the
mcp-builder guidance.
- Enrich proto descriptions (single source of truth, flows to OpenAPI + MCP
tool descriptions): document the memo `filter` CEL grammar with fields and
examples (replacing the dangling "Refer to Shortcut.filter"), clarify the
created_ts/updated_ts vs create_time/update_time naming, the visibility
enum, the declarative replace semantics of Set* ops, and steer tag filters
to `"x" in tags` (not the unsupported `tag == "x"`).
- Mark SetMemoAttachments / SetMemoRelations idempotent via a per-operation
override the HTTP-method heuristic can't express.
- Curate two read-only orientation tools: shortcut_list_shortcuts (surfaces
reusable CEL filters) and auth_get_current_user (the single allowed
auth/identity op, for resolving the current user); guard test updated to
keep the rest of the auth/user surface excluded.
- Add a task-level evaluation suite (server/router/mcp/evals) with 10
verified questions, pinned to the deterministic demo seed.
Reject non-standard truthy numeric expressions in filters and document the parser as a supported subset of standard CEL syntax.
- remove legacy filter rewrites
- support standard equality in tag exists predicates
- add regression coverage for accepted and rejected expressions
Embeds a Model Context Protocol (MCP) server into the Memos HTTP
process, exposing memo operations as MCP tools at POST/GET /mcp using
Streamable HTTP transport.
Authentication is PAT-only — requests without a valid personal access
token receive HTTP 401. Six tools are exposed: list_memos, get_memo,
create_memo, update_memo, delete_memo, and search_memos, all scoped to the authenticated user.
