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.
basic-ftp: Incomplete CRLF Injection Protection Allows Arbitrary FTP Command Execution via Credentials and MKD Commands
basic-ftp has FTP Command Injection via CRLF
basic-ftp vulnerable to denial of service via unbounded memory consumption in Client.list()
basic-ftp allows a malicious FTP server to cause client-side denial of service via unbounded multiline control response buffering

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
17/17 tools missing one or more hints — get_printer_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); extend_stl_base (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); scale_stl (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +14 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
6/17 tools referenced in tests (35%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 4 high severity in production deps — basic-ftp@5.2.0 (high), basic-ftp@5.2.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dependency freshness
2/8 production deps stale: xml2js@2024-05-31 (2.3y), bambu-node@2024-08-19 (2.1y)

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.
