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
19/19 tools missing one or more hints — cal_list_calendars (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cal_list_events (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cal_get_event (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +16 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.
Tool test coverage
11/19 tools referenced in tests (58%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
7 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 1 high severity in production deps — @modelcontextprotocol/sdk@1.0.0 (high), uuid@11.0.5 (low)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Domain consistency
npm scope @anthropic doesn't match GitHub owner swamirama
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
