Enables AI assistants to fully automate n8n instances via 34 MCP tools, covering workflow creation, execution debugging, credential management, environment variables, tags, and user administration through natural language.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

N8N_API_KEYyour_n8n_api_key_hereN8N_BASE_URL"": "http://localhost:5678",All four hints declared on every tool
34/34 tools missing one or more hints — list_workflows (missing: destructiveHint, idempotentHint, openWorldHint); get_workflow (missing: destructiveHint, idempotentHint, openWorldHint); create_workflow (missing: idempotentHint, openWorldHint), +31 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
Only 0/34 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 15 high severity in production deps — @modelcontextprotocol/sdk@1.0.0 (high), axios@1.7.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
