Covers the infra side well. Latency characteristics aren't documented — that's a gap for SLO-sensitive setups.

03SECURITYWHAT WE CHECKED
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.
Security tierTier 1, Contained.No network access and no credentials. Runs entirely on its own. What tiers mean
Install-time hooks & dependencies1 finding
HIGHpackage.jsonnpm 'prepare' lifecycle hook: install hook runs an opaque or unrecognized command at install time, before any code review: the arbitrary-code-on-install supply-chain vector.
Runs code / shell commandsno flags
Whether the server can execute commands on your machine.
Secrets & credentialsno flags
How it reads, logs, or transmits keys and tokens. Scam/wallet-drainer patterns land here.
Network calls out19 findings
MEDIUM__tests__/handlers/npm-metrics.test.ts:91Hardcoded external endpoint 'github.com'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.
MEDIUM__tests__/handlers/npm-readme-cdn.test.ts:58Hardcoded external endpoint 'cdn.jsdelivr.net'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.

Prompt-injection passthrough1 finding
INFOindex.tsHEURISTIC: 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.
