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.
When Vitest UI server is listening, arbitrary file can be read and executed
@hono/node-server has authorization bypass for protected static paths via encoded slashes in Serve Static Middleware
Hono vulnerable to arbitrary file access via serveStatic vulnerability
Hono: Path traversal in toSSG() allows writing files outside the output directory
@hono/node-server: Middleware bypass via repeated slashes in serveStatic
SKIP_INTEGRATIONSTM_CLIENT_IDSTM_CLIENT_SECRETXDG_CACHE_HOMEPORTTool 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
5/5 tools missing one or more hints — buscar_parada (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); como_llegar (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); proximos_buses (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 inputs are validated
Only 0/5 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
4/5 tool handlers wrap calls in try/catch (80%)
Wrap each tool handler body in try/catch and return a structured error response.
Production dependencies are patched
0 critical, 2 high severity in production deps — @hono/node-server@1.19.9 (high), hono@4.12.3 (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.
