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.

Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
axios Vulnerable to Full Man-in-the-Middle via Prototype Pollution Gadget in `config.proxy`
axios Vulnerable to Credential Theft and Response Hijacking via Prototype Pollution Gadget in Config Merge
Axios: Header Injection via Prototype Pollution
Allocation of Resources Without Limits or Throttling in Axios
Axios: Regular Expression Denial of Service (ReDoS) via Cookie Name Injection
SENTRY_RELEASETool 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
25/25 tools missing one or more hints — get-body-measurements (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get-body-measurement (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); create-body-measurement (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +22 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.
Production dependencies are patched
0 critical, 10 high severity in production deps — axios@1.14.0 (high), axios@1.14.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
