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.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
upload-fileUpload a local file to the remote SSH server using SFTP.
upload-contentUpload direct text or base64 content to the remote SSH server using SFTP.
terminal-startStart an interactive terminal session on the remote SSH server. Reuses a managed session by default unless multiSession is true.
terminal-writeWrite input into an existing interactive terminal session. Use this for ordinary commands and sudo-interactive flows instead of exec tools.
terminal-readRead buffered output from an interactive terminal session.
terminal-resizeResize an existing interactive terminal session.
terminal-closeClose an interactive terminal session locally. The remote marker file is left for the server-side watcher to clean up if it is still present.
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
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
TERMSSH_MCP_DISABLE_MAINTERMSSH_MCP_TESTTool 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
7/7 tools missing one or more hints — upload-file (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); upload-content (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); terminal-start (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 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 0/7 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 2 high severity in production deps — @modelcontextprotocol/sdk@1.17.5 (high), @modelcontextprotocol/sdk@1.17.5 (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.
