Risk Summary

Safe With Normal Controls

Dep Visibility is the main signal, but overall risk remains within an acceptable range.

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

Recommended action: No high-risk findings were detected in this scan, but you should still apply least-privilege defaults and rescan after changes.

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

Security Findings (58)

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×9

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

    n8n_get_workflown8n_delete_workflown8n_activate_workflown8n_deactivate_workflown8n_execute_workflown8n_list_executionsn8n_get_executionn8n_delete_executionn8n_retry_execution

    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 ×27

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

    Fix: Review and remediate the identified issue.

  • InfoAS-002

    ⚠️Excessive Permissions ×21

    declared capabilities: code/command execution

    n8n_get_workflown8n_deactivate_workflown8n_list_executionsn8n_get_execution

    declared capabilities: filesystem access

    n8n_create_workflown8n_update_workflown8n_update_workflow_tagsn8n_update_credentialn8n_delete_credentialn8n_create_tagn8n_update_tagn8n_delete_tagn8n_get_usern8n_delete_usern8n_update_user_role

    declared capabilities: code/command execution, filesystem access

    n8n_delete_workflown8n_delete_execution

    declared capabilities: code/command execution, HTTP requests

    n8n_activate_workflown8n_execute_workflow

    declared capabilities: code/command execution, network access

    n8n_retry_execution

    declared capabilities: filesystem access, database access

    n8n_create_credential

    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-010

    🔑Insecure Secret Handling

    n8n_get_credential_schema:input parameter "credentialType" accepts a credential (informational; not evidence of insecure handling)

    Fix: Avoid accepting raw credentials as input parameters. Use secret managers (e.g. 1Password CLI, AWS Secrets Manager) and ensure credentials are never logged or stored in agent traces.

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-mcp-server"

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