Safe MCP server + CLI for testing, scoring, and inspecting n8n workflows
Config-driven test suites with tiered scoring, execution traces, and a built-in node catalog.
Why?
Most n8n MCP integrations give you full admin access — credentials, destructive operations, auto-fix loops. That's fine for development, but risky for CI, shared environments, or autonomous agents.
n8n-workflow-tester-safe takes a different approach:
| Feature | This MCP | Full admin MCPs |
|---|---|---|
| Test workflows with scoring | Yes | No |
| Execution traces (lightweight) | Yes | No |
| Node catalog with suggestions | Yes | No |
| Credential management | Excluded | Yes |
| Secret lifecycle | Excluded | Yes |
| Auto-fix loops | Excluded | Some |
Result: A focused tool that does testing and inspection really well, without the risk surface of a full admin wrapper.
