The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

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
20/20 tools missing one or more hints — mcp (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); agentdelegate (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); bash (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +17 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
12/20 tools referenced in tests (60%)
Write tests that reference each tool by name so every tool has at least one test.
No access to sensitive paths
Reads sensitive paths: ~/.cow/.env, ~/.weixin_cow_credentials.json
Remove reads of sensitive system paths. If you genuinely need them, document why in the README.
No eval / new Function
1 eval() or new Function() call — dynamic code execution
Replace eval / Function with explicit parsing or safer alternatives.
Readable source code
3 files are minified or bundled, which is usually build output rather than concealment
Ship unminified, readable source.
Secrets never reach shell commands
1 secret value passed to a subprocess as an argument — no shell is invoked, so there is nothing to inject into
Never pass secrets through shell commands. Use library APIs that accept credentials as arguments.

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.
