StatusCheckPolicyResult
PASS Listed on the official MCP registry §1.1
Listed on registry.modelcontextprotocol.io as com.browser-use/browser-use. 1 finding
  • Registry entry: com.browser-use/browser-use ↗
PASS Source repository is public and maintained §1.2
Active repository with a license. 5 findings
  • Repository ↗
  • Last push: 0 days ago
  • Stars: 107083
  • License: MIT
  • Security policy (SECURITY.md): absent
WARN Published package is consistent and attested §1.3
Minor integrity gaps: no PyPI trusted-publishing provenance. 5 findings
  • Package: browser-use@0.13.7 ↗
  • Ecosystem: PyPI
  • Age: 628 days
  • Repo field matches source repo: true
  • Trusted-publishing provenance: absent
PASS Tool surface is inspectable and proportionate §2.1–§2.4
Package source scanned. Capabilities detected: process-execution, network-egress, filesystem. Reported as capability risk (§2.4); whether each is essential to the server's stated purpose is §2.3 and remains a manual judgement. 5 findings
  • process-execution (child process execution): browser_use/cli.py
  • network-egress (outbound network calls): browser_use/init_cmd.py
  • filesystem (filesystem write/delete): browser_use/browser/profile.py
  • filesystem (filesystem write/delete): browser_use/tokens/service.py
  • Detected capabilities: process-execution, network-egress, filesystem
INFO Transport & authentication §3

Local (stdio) server: runs with host-process privileges by design. Transport checks apply to remote servers; scrutiny shifts to §1/§2.
FAIL No known vulnerabilities (OSV.dev) §4.1
2 advisory(ies) on record for browser-use @0.13.7 (PyPI) - review whether the evaluated version is affected. 2 findings
  • GHSA-x39x-9qw5-ghrf: Browser Use allows bypassing `allowed_domains` by putting a decoy domain in http auth username portion of a URL ↗
  • PYSEC-2026-300: Browser Use allows bypassing `allowed_domains` by putting a decoy domain in http auth username portion of a URL ↗
PASS Server-supplied instructions free of poisoning indicators §5.1–§5.4

No poisoning indicators found across 18 server-supplied text item(s).
What this grade covers
  • Provenance & supply-chain integrity (§1)
  • Tool surface & capability risk (§2)
  • Transport & authentication (§3)
  • Known CVEs via OSV.dev (§4)
  • Instruction/tool poisoning patterns (§5)

Limitations: pattern-based only (no semantic injection detection), static npm analysis (live server instructions not retrieved for package-only scans), single-server scope (no cross-server toxic flow analysis). See the full policy.
