Security flags foundOur static scan found signals worth reviewing before you trust this with an agent. See exactly what, per check, below.

Telemetry disclosureUndisclosed egress detected.Static checks found network calls the docs do not mention. Disclosed telemetry is common and fine, silent telemetry is the finding.

Install-time hooks & dependenciesno flags

Code that runs when you install it, before you ever call a tool.

Runs code / shell commands1 finding

INFOsrc/__tests__/healthcheck.test.ts:2 — Code-execution call site (node child_process) in TEST code. Down-weighted to informational: this is the test exercising the server, not the server's runtime surface.

Prompt-injection passthrough1 finding

INFOsrc/mcp/tools.ts — HEURISTIC: this file both fetches external content and returns content as tool output, with no obvious sanitization. External text returned into tool output can carry instructions an agent obeys (prompt-injection passthrough). Confirm manually; this is a hint, not proof.

Permission scope breadthno flags

How much access it asks for versus what its job needs.

How to read this: these are static checks over the source at a point in time. They catch the patterns above, not everything. Absence of a flag is not absence of danger, and a tool that runs cleanly can still behave differently once installed. We do not call any tool simply "safe". Runtime-behavior checks are the next layer we are adding.
