Risk Summary

Block in Production

Supply Chain CVEs + Excessive Permissions risk is significant. Avoid using this in production agents.

Potential impact: Known dependency vulnerabilities can be exploited during install or runtime and widen the attack surface.

Recommended action: This tool should stay disabled in production agents until the flagged risks are fixed and the scan is clean.

Security Findings (46)

  • CriticalAS-006

    💻Arbitrary Code Execution ×2

    heuristic signal

    tool name or description implies arbitrary script/code execution (evaluate_script, execute javascript, etc.)

    browser_evaluatebrowser_run_code_unsafe

    Fix: This tool can execute arbitrary code or shell commands on the host system. Remove it unless strictly required. If kept: (1) restrict access to trusted users/agents only, (2) require human approval before each invocation (Claude Desktop: set approval_required: true; other clients: enable equivalent confirmation), (3) use the most restrictive sandbox or read-only mode available, and (4) never expose this tool to untrusted input sources.

  • HighAS-004

    📦Supply Chain CVEs (OSV) ×23

    GO-2026-5024 in golang.org/x/[email protected]: Invoking integer overflow in NewNTUnicodeString in golang.org/x/sys/windows (upgrade to 0.44.0)

    Fix: Upgrade or replace the vulnerable dependency. Pin all dependency versions and enable automated CVE scanning (Dependabot or OSV Scanner).

  • HighAS-002

    ⚠️Excessive Permissions ×6

    tool declares exec permission

    browser_evaluatebrowser_run_code_unsafe

    tool declares network permission

    browser_navigatebrowser_network_requestsbrowser_network_requestbrowser_tabs

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • MediumAS-002

    ⚠️Excessive Permissions ×9

    tool declares fs permission

    browser_console_messagesbrowser_evaluatebrowser_file_uploadbrowser_dropbrowser_network_requestsbrowser_network_requestbrowser_run_code_unsafebrowser_take_screenshotbrowser_snapshot

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×6

    tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

    browser_evaluatebrowser_navigatebrowser_network_requestsbrowser_network_requestbrowser_run_code_unsafebrowser_tabs

    Fix: Declare explicit rate-limit, timeout, and retry configuration for all network and execution tools. Implement exponential back-off and surface resource state to the calling agent.

Scan this tool yourself

Reproduce this audit locally, integrate into CI, or let your agent audit its own tools.

Install once, then scan any MCP server:

$ curl -sfL https://raw.githubusercontent.com/AgentSafe-AI/tooltrust-scanner/main/install.sh | bash
$ tooltrust-scanner scan --server "npx -y playwright-mcp"

Adjust the package name if your npm registry name differs from the tool ID. View source
