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 2, Networked.Reaches the live web, but needs no secrets. What tiers mean
Install-time hooks & dependencies1 finding
HIGHpackage.json — npm '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 commands50 findings
MEDIUMscripts/test.mjs:10 — Code-execution surface: a node child_process call site. The server can run commands on the host; review what it executes and whether any input reaches it.
MEDIUMscripts/test.mjs:73 — Code-execution surface: a exec/spawn call site. The server can run commands on the host; review what it executes and whether any input reaches it.
MEDIUMscripts/test.mjs:89 — Code-execution surface: a exec/spawn call site. The server can run commands on the host; review what it executes and whether any input reaches it.
MEDIUMscripts/update-lighthouse.ts:7 — Code-execution surface: a node child_process call site. The server can run commands on the host; review what it executes and whether any input reaches it.
MEDIUMscripts/update-lighthouse.ts:22 — Code-execution surface: a exec/spawn call site. The server can run commands on the host; review what it executes and whether any input reaches it.
MEDIUMscripts/update-lighthouse.ts:25 — Code-execution surface: a exec/spawn call site. The server can run commands on the host; review what it executes and whether any input reaches it.

Secrets & credentials2 findings
INFOscripts/count_tokens.ts:12 — Reads a secret-shaped environment variable. Ordinary for a credentialed server; recorded for completeness.
INFOscripts/eval_gemini.ts:180 — Reads a secret-shaped environment variable. Ordinary for a credentialed server; recorded for completeness.
Network calls out28 findings
MEDIUMrollup.config.mjs:9 — Hardcoded external endpoint 'www.apache.org'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.
MEDIUMrollup.config.mjs:19 — Hardcoded external endpoint 'github.com'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.
MEDIUMrollup.config.mjs:144 — Hardcoded external endpoint 'b'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.
MEDIUMtests/cli.test.ts:367 — Hardcoded external endpoint 'a.com'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.
MEDIUMtests/cli.test.ts:368 — Hardcoded external endpoint 'b.com'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.
MEDIUMtests/server.ts:25 — Hardcoded external endpoint 'source.chromium.org'. STATIC signal only: this flags a declared destination for human or dynamic-egress confirmation; it does NOT assert exfiltration.

Prompt-injection passthrough4 findings
INFOtests/McpResponse.test.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.
INFOtests/tools/extensions.test.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.
INFOtests/tools/input.test.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.
INFOtests/tools/network.test.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 breadth2 findings
INFOsrc/bin/check-latest-version.ts — HEURISTIC: broad capability surface in one file (filesystem, network, subprocess). A scope-breadth hint: the more distinct host capabilities a server touches, the more a buyer is granting. Confirm it matches the stated function.
INFOsrc/daemon/client.ts — HEURISTIC: broad capability surface in one file (filesystem, network, subprocess). A scope-breadth hint: the more distinct host capabilities a server touches, the more a buyer is granting. Confirm it matches the stated function.
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.
