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 (50)

  • CriticalAS-006

    💻Arbitrary Code Execution

    heuristic signal

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

    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.

    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

    evaluate_scriptnavigate_page

    tool declares network permission

    get_network_requestlist_network_requestsnavigate_pagenew_page

    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

    evaluate_scriptget_network_requestlighthouse_auditperformance_start_traceperformance_stop_tracetake_heapsnapshottake_screenshottake_snapshotupload_file

    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-002

    ⚠️Excessive Permissions

    emulate:tool declares http permission

    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 ×4

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

    emulateevaluate_scriptget_network_requestlist_network_requests

    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 chrome-devtools-mcp"

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