MOCHI_API_KEY[](https://vercel.com/new/clone?repository-url=https://github.com/shunkus/mochi-mcp-server&env=&envDescription=Your%20Mochi%20Cards%20API%20key)Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
17/17 tools missing one or more hints — create_card (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_card (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_cards (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +14 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
