Risk Summary

Needs Approval

Excessive Permissions plus Missing Rate Limits raises enough risk that this tool should not be auto-trusted.

Potential impact: The agent may gain overly broad access to files, network, databases, or execution capabilities.

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 (35)

  • CriticalAS-006

    💻Arbitrary Code Execution

    heuristic signal

    n8n_explain_execution: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.

    ⚠️Excessive Permissions ×10

    tool declares exec permission

    n8n_scaffold_noden8n_generate_workflown8n_explain_executionn8n_list_executions

    tool declares network permission

    n8n_generate_workflown8n_list_workflowsn8n_get_workflown8n_create_workflown8n_activate_workflown8n_list_executions

    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 ×4

    tool declares fs permission

    n8n_scaffold_noden8n_lint_workflown8n_create_workflow

    tool declares env permission

    n8n_list_workflows

    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 ×9

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

    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.

  • LowAS-002

    ⚠️Excessive Permissions ×2

    tool declares http permission

    n8n_generate_workflown8n_lint_workflow

    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-014

    ℹ️Dependency Inventory Unavailable ×9

    Tool did not expose metadata.dependencies or repo_url, so supply-chain coverage is limited.

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 n8n"

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