MCP_MODE |
Required: Set to stdio when run from a desktop client; the docs say it is required for Claude Desktop. |
|---|---|
LOG_LEVEL |
Optional: Log level; the docs' example uses error. |
DISABLE_CONSOLE_OUTPUT |
Optional: Set to true to keep console output off stdout. |
N8N_API_URL |
Optional: URL of your n8n instance; needed for the n8n management tools. |
N8N_API_KEY |
Optional: n8n API key; needed for the n8n management tools. |
N8N_MCP_ACCESS_TOKEN |
Optional: Instance-level MCP key from n8n settings, for agents, node resource discovery and some run modes. |
N8N_CF_CLIENT_ID |
Optional: Cloudflare Access client ID, when the n8n instance is behind Cloudflare Access. |
N8N_CF_CLIENT_SECRET |
Optional: Cloudflare Access client secret, when the n8n instance is behind Cloudflare Access. |
DISABLED_TOOLS |
Optional: Comma-separated tools to turn off, for example for a read-only deployment. |
DISABLED_TOOL_OPERATIONS |
Optional: Write operations to block inside tools that mix read and write. |
N8N_MCP_TELEMETRY_DISABLED |
Optional: Set to true to turn off telemetry (Docker); with npx run n8n-mcp telemetry disable. |
What it does
n8n-MCP gives an assistant structured knowledge of n8n, the workflow automation platform: documentation, properties and operations for about 2,950 nodes (core and community), real-world example configurations, and a library of workflow templates. With it an assistant can find the right nodes, read their settings, and validate a node or a whole workflow before it is built.
When it is given the URL and API key of an n8n instance, a second set of tools manages that instance: create, update, validate, auto-fix, version and delete workflows, deploy templates, run workflows and read executions, and manage folders, data tables, credentials, evaluations and agents, plus a security audit. Some features also need the instance-level MCP access token from n8n's settings.
It runs locally with npx n8n-mcp (Node.js, with a pre-built node database included) or from the Docker image ghcr.io/czlonkowski/n8n-mcp; the docs say MCP_MODE=stdio is required for Claude Desktop. It can also be deployed over HTTP, and the maker runs a hosted version at dashboard.n8n-mcp.com with a free tier of 100 tool calls a day. The README warns never to edit production workflows directly with an assistant: copy them, test in development and keep backups.
Tools 28
tools_documentation- Get documentation for any of the server's tools.
search_nodes- Full-text search across n8n nodes, including community and verified community nodes, optionally with example configurations.

validate_node- Validate a node configuration, from a quick required-fields check to full validation with profiles.
validate_workflow- Validate a complete workflow, including AI Agent workflows.
search_templates- Search n8n workflow templates by keyword, by nodes used, by task, or by metadata such as complexity.
get_template- Get a template's workflow JSON (nodes only, structure or full).
n8n_create_workflow- Create a new workflow with nodes and connections in your n8n instance.
n8n_get_workflow- Retrieve a workflow (full, details, structure or minimal).
