The source identifies czlonkowski/n8n as the repository and maintainer, with an MIT license and the repository root as the server path. The server manifest is not cached, and the README does not specify a transport protocol or complete client installation configuration.

Why each score
Reliability 8/20
The README lists a substantial tool surface, validation workflow, and several deployment paths, but the server manifest is unavailable and no verifiable source, CI workflow, or committed test files are supplied. The “5418 passing” badge is not execution evidence under this review. The happy path is plausible, but initialization handshake behavior, declaration consistency, dependency control, and error handling cannot be confirmed, so the static calibration requires a deduction.
Security and permissions 12/20
The README identifies API-key and Cloudflare credential environment variables and states that Cloudflare credentials are confined to the N8N_API_URL origin. It also documents disabling write, delete, test, credential, and data-table tools, plus blocking destructive operations within bundled tools. These are meaningful permission and data-boundary controls. However, high-impact workflow, credential, data-table, execution, and deletion tools remain available, and there is no source-level evidence of default confirmation, complete data-flow controls, or authorization enforcement, so this is not near full marks.
Maintenance 13/20
The project states an MIT license, is not archived, and provides a changelog, contribution guide, sponsorship channel, and explicit n8n version information, giving reasonable ownership and maintenance signals. The supplied material does not provide verifiable release history, commit cadence, dependency-update practice, vulnerability-response channel, or issue-response evidence. Stars and open issues are discovery signals only and add no points.
Documentation 14/20
The README covers self-hosting, Docker, Railway, cloud deployment, n8n integration, Cloudflare authentication, security hardening, privacy telemetry, HTTP deployment, workflow diffs, and client integrations. It also describes the tools and their main modes, making the documentation structure strong. Points are deducted because the linked documentation contents are not supplied, the manifest is missing, and costs, limits, troubleshooting, and declared behavior cannot be independently reviewed; the README is also untrusted evidence.
Setup experience 11/20
The README offers a hosted dashboard, a stated free quota, self-hosting options, and setup-document links for several mainstream clients and platforms. The actual installation commands, client configuration examples, runtime prerequisites, and server manifest are not provided, so the complete path from environment preparation to a verified MCP connection cannot be established. This supports a usable but manual and incompletely evidenced setup score.

Fit and risk

What it can accessUses the networkChanges third-party account data

Best for

  • Developers building n8n automation with Claude, Cursor, Windsurf, VS Code, Codex, or Antigravity.
  • n8n users who need node documentation, template discovery, and workflow validation.
  • Teams that want to self-host n8n-MCP or use it through the hosted dashboard.

Not for

  • Automation scenarios that do not use n8n.
  • Users who need n8n instance management without configuring the n8n API.
  • Production workflow changes made without testing.

Required permissions

  • Permissions required for basic node, documentation, template, and validation features are not specified in the source.
  • n8n management features require N8N_API_URL and N8N_API_KEY.
  • Credential and data-table tools may access sensitive n8n data; the source recommends disabling them in governance-sensitive environments.

Risks and side effects

  • AI-generated results may be unpredictable; the source explicitly warns against editing production workflows directly.
  • Copy workflows, test in development, back up important workflows, and validate changes before deployment.
  • Enabling workflow write, delete, credential, or data-table management increases potential impact.

Setup

Before you start

Runtime：Node.js · Docker · Hosted (no local runtime)

N8N_API_KEY optionalsecret API key generated in your n8n instance (Settings → API), used together with N8N_API_URL.
N8N_CF_CLIENT_SECRET optionalsecret Cloudflare Access service token Client Secret used to authenticate n8n API requests.
Other optional settings (4)
N8N_API_URL optional Base URL of your n8n instance API; required to use the n8n management tools.
N8N_CF_CLIENT_ID optional Cloudflare Access service token Client ID, needed when your n8n sits behind Cloudflare Zero Trust.
DISABLED_TOOLS optional Comma-separated list of tools to disable entirely, for read-only deployments.
DISABLED_TOOL_OPERATIONS optional Finer-grained control to block specific destructive operations (e.g. delete, run) within tools.

Register at dashboard.n8n-mcp.com to obtain an API key and connect an MCP client, or follow the repository's self-hosting guide using npx, Docker, Railway, or local installation. To connect an n8n instance, configure N8N_API_URL and N8N_API_KEY. If the instance is behind Cloudflare Access, N8N_CF_CLIENT_ID and N8N_CF_CLIENT_SECRET can also be configured.

Check that it works

After connecting, search_nodes and tools_documentation should appear in your client's tool list; call n8n_health_check to confirm n8n API connectivity, or ask it to search for webhook-related nodes to prove the server is working.

Troubleshooting

  1. Check that N8N_API_URL and N8N_API_KEY are configured correctly.
  2. Use n8n_health_check to check API connectivity and features.
  3. For n8n instances behind Cloudflare Access, check N8N_CF_CLIENT_ID and N8N_CF_CLIENT_SECRET.
  4. Consult the repository's self-hosting, HTTP deployment, and n8n deployment guides.

Things to try

Once connected, you can ask your AI assistant things like:

  • Search n8n workflow templates for Slack notifications
  • Show me the configuration properties of the n8n-nodes-base.webhook node
  • Validate this workflow's node configs and connections before I deploy it
  • List recent failed executions from my n8n instance

Overview

n8n-MCP is a Model Context Protocol server that gives AI assistants access to n8n node documentation, properties, operations, templates, and workflow validation. It supports searching and configuring core and community nodes, and can manage workflows, executions, credentials, and data tables when the n8n API is configured.
