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
85/85 tools missing one or more hints — agent_diary_append (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); agent_diary_read (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); agents_get (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +82 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.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
Only 2/85 tools referenced in tests (2%)
Write tests that reference each tool by name so every tool has at least one test.
Tests pass
npm test failed — tests do not pass
Make sure npm test runs cleanly. Common cause: missing build step or missing env vars.
Shell command execution
41 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Secrets not logged
2 secret values sent to console.log
Redact or omit secret values from log output.
Production dependencies are patched
0 critical, 5 high severity in production deps — @modelcontextprotocol/sdk@1.12.1 (high), @modelcontextprotocol/sdk@1.12.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
4/26 production deps abandoned (no release in 2+ years): tree-sitter-dart@2023-02-24 (3.5y), gray-matter@2023-07-12 (3.1y), hnswlib-node@2024-03-11 (2.4y)
Domain consistency
npm scope @cortexmd doesn't match GitHub owner leicas
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
