Risk Summary

Needs Approval

Dep Visibility plus Excessive Permissions raises enough risk that this tool should not be auto-trusted.

Potential impact: This finding indicates the tool should be reviewed before it is trusted.

Recommended action: Keep this tool behind manual approval and avoid unattended runs until the risky capabilities are narrowed or removed.

Suggested policy: keep this tool behind manual approval, do not allow unattended runs, and re-scan after narrowing risky permissions.

Security Findings (42)

  • CriticalAS-006

    💻Arbitrary Code Execution

    heuristic signal

    browser_run_code_unsafe: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.

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×5

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

    browser_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.

  • InfoAS-014

    ℹ️Dependency Inventory Unavailable ×24

    No metadata.dependencies or repo_url were exposed by this MCP server, and no local project manifest could be inferred from the launch command.

    Fix: Review and remediate the identified issue.

  • InfoAS-002

    ⚠️Excessive Permissions ×11

    declared capabilities: filesystem access

    browser_console_messagesbrowser_evaluatebrowser_file_uploadbrowser_dropbrowser_take_screenshotbrowser_snapshot

    declared capabilities: network access

    browser_navigatebrowser_tabs

    declared capabilities: network access, filesystem access

    browser_network_requestsbrowser_network_request

    declared capabilities: code/command execution, filesystem access

    browser_run_code_unsafe

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

  • InfoAS-006

    💻Arbitrary Code Execution

    browser_evaluate:tool name or description implies arbitrary script/code execution — capability unconfirmed (no exec permission or code/script/eval input property found)

    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.

Scan this tool yourself
