Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

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.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
express-rate-limit: IPv4-mapped IPv6 addresses bypass per-client rate limiting on servers with dual-stack network
undici vulnerable to cross-user information disclosure and parse-time crash via degenerate private cache directives
Undici: Malicious WebSocket 64-bit length overflows parser and crashes the client
Undici has Unhandled Exception in WebSocket Client Due to Invalid server_max_window_bits Validation
CLIENT_PORTHTTP_PROXYSERVER_PORTAll four hints declared on every tool
28/28 tools missing one or more hints — list_toolsets (missing: idempotentHint, openWorldHint); list_tools (missing: idempotentHint, openWorldHint); get_tool_input_schema (missing: idempotentHint, openWorldHint), +25 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 2/28 tools referenced in tests (7%)
Write tests that reference each tool by name so every tool has at least one test.
No access to sensitive paths
Reads sensitive paths: .env
Remove reads of sensitive system paths. If you genuinely need them, document why in the README.
Shell command execution
2 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Dev dependencies
7 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
