Exposure: Limited

Runs commands or loads code on your machine, but does not reach secrets or other agents.

What this server can reach, from a static read of the shipped code. Nothing was executed and nothing here is a verdict: a browser tool has to run commands and an API wrapper has to call its API. Decide what fits your setup.

    Loads a .env, .npmrc or config file. Normal for a server that needs an API key.

  • Runs unpinned packages at runtime2 places

    Executes npx or uvx without a version, so a compromised upstream release would run.

Not detected: reads environment variables in bulk, sends conversation content outward, runs shell commands, reads or writes other agents' configuration, accesses credential files, uses elevated privileges, installs itself to run later, matches a known malicious pattern.
