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.
cnpj_lookupLook up Brazilian company information by CNPJ number
cep_lookupLook up Brazilian postal code information by CEP
cnpj_searchSearch the web for information about Brazilian companies, CNPJ numbers, people, and more using DuckDuckGo.

Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

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
5/5 tools missing one or more hints — cnpj_lookup (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cep_lookup (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cnpj_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +2 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
3/5 tools referenced in tests (60%)
Write tests that reference each tool by name so every tool has at least one test.
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.18.2 (high), @modelcontextprotocol/sdk@1.18.2 (high)
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.
Dependency freshness
1/9 production deps stale: async-mutex@2024-03-11 (2.5y)
Domain consistency
npm scope @aredes.me doesn't match GitHub owner didiye
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
