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.
ws affected by a DoS when handling a request with many HTTP headers
ws: Memory exhaustion DoS from tiny fragments and data chunks
uuid: Missing buffer bounds check in v3/v5/v6 when buf is provided
ws: Uninitialized memory disclosure
WS_PORTListens on ws://localhost:3055 by default. Override with .Tool annotations
2/42 tools have annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
42/42 tools missing one or more hints — get_figma_comments (missing: destructiveHint, idempotentHint); post_figma_comment (missing: idempotentHint); get_document_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +39 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
35/42 tool handlers declare input schemas (83%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
40/42 tool handlers wrap calls in try/catch (95%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 2 high severity in production deps — ws@8.16.0 (high), ws@8.16.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
