🚨

Known vulnerabilities in dependencies: 1 critical, 3 high

Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.

🔐

You'll be asked for 1 credential: SUDO_PASSWORD

These are read from process.env at runtime. Make sure you trust where they’ll be sent.

// tools this server exposes47 tools

configLOCAL_MODEfalse Set to true to manage the local machine directly (no SSH)

configLOG_PATHS/var/log Comma-separated list of allowed log file path prefixes

configSSH_PORTNo 22 SSH port

configSSH_STRICT_HOST_CHECKNo true Set to false to skip host key verification

// quality suggestions

All four hints declared on every tool

47/47 tools missing one or more hints — read_file (missing: idempotentHint, openWorldHint); write_file (missing: idempotentHint, openWorldHint); list_directory (missing: idempotentHint, openWorldHint), +44 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

39/47 tool handlers declare input schemas (83%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tool handlers catch errors

Only 0/47 tool handlers wrap calls in try/catch (0%)

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.).

Tool test coverage

Only 0/47 tools referenced in tests (0%)

Write tests that reference each tool by name so every tool has at least one test.

Shell command execution

1 child_process call — runs shell commands

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Production dependencies are patched

0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.1 (high), @modelcontextprotocol/sdk@1.12.1 (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.

// full audit trail

The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.

// improvement guidance — verified publishers only

We have 8 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
