97 dependencies, 1 flagged: @playwright/test
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
9/9 tools missing one or more hints — start_session (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); create_new_diagram (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); edit_diagram (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +6 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 inputs are validated
5/9 tool handlers declare input schemas (56%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Shell command execution
33 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, 15 high severity in production deps — @xmldom/xmldom@0.9.8 (high), @xmldom/xmldom@0.9.8 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
7 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
4/64 production deps abandoned (no release in 2+ years): server-only@2022-09-03 (3.8y), pako@2022-11-07 (3.6y), tailwindcss-animate@2023-08-28 (2.8y)
