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.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@hono/node-server has authorization bypass for protected static paths via encoded slashes in Serve Static Middleware
hono: CORS Middleware reflects any Origin with credentials when `origin` defaults to the wildcard
Hono vulnerable to arbitrary file access via serveStatic vulnerability
@hono/node-server: Middleware bypass via repeated slashes in serveStatic
Node.js Adapter for Hono: Path traversal in `serve-static` on Windows via encoded backslash (`%5C`)

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
22/22 tools missing one or more hints — microcms_create_content_draft (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); microcms_create_content_published (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); microcms_create_contents_bulk_published (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +19 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
Only 1/22 tools referenced in tests (5%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 3 high severity in production deps — @hono/node-server@1.19.9 (high), hono@4.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
