Uses `npx` (confidence: high): ```json "mcpServers": { "n8n-mcp-community": { "command": "npx", "args": ["-y","--yes"], "env": { "N8N_API_URL": "", "N8N_API_KEY": "", "N8N_MCP_MODE": "" } } } ``` **Requires environment variables:** `N8N_API_URL`, `N8N_API_KEY`, `N8N_MCP_MODE` — the values above are empty placeholders; fill in real credentials before running (see the repository for what each one is for). ## Documentation & README # n8n MCP Community [![n8n-mcp-community MCP server](https://glama.ai/mcp/servers/drzamarian/n8n-mcp-community/badges/score.svg)](https://glama.ai/mcp/servers/drzamarian/n8n-mcp-community) # A security-focused Model Context Protocol server for self-hosted n8n Community Edition Give your AI client 44 tools for self-hosted n8n Community Edition. Manage workflows, nodes, runs, credentials, tags, users, and diagnostics. No paid n8n features. The server makes no external AI calls. [![Install with npm](https://img.shields.io/badge/Install_with-npm-CB3837?logo=npm&logoColor=white)](#install) [![Download MCPB](https://img.shields.io/badge/Download-MCPB-6B4EFF)](https://github.com/drzamarian/n8n-mcp-community/releases/latest) [![Read the docs](https://img.shields.io/badge/Read-the_docs-1F6FEB)](docs/README.md) ## Install You need Node.js 22 or 24, your n8n URL, and an n8n API key. ### Install ```bash npm install --global n8n-mcp-community@latest ``` `--global` installs the command once. Use `npx` below if you do not want a global install. ### Connect ```json { "mcpServers": { "n8n-community": { "command": "n8n-mcp-community", "env": { "N8N_API_URL": "https://n8n.example.com", "N8N_API_KEY": "replace-with-a-dedicated-api-key", "N8N_MCP_MODE": "read-only" } } } } ``` Restart your client. You should see 44 tools, 5 resources, and 4 prompts. If the client cannot find the command, run `command -v n8n-mcp-community` on macOS/Linux or `where n8n-mcp-community` on Windows. Put that full path in `"command"`. Want no global install? Copy this command into the client configuration shown in the full guide: ```bash npx --yes n8n-mcp-community@latest ``` Want the Claude Desktop app flow? Use the MCPB below. See the full [installation guide](https://github.com/drzamarian/n8n-mcp-community/blob/HEAD/docs/installation.md) for updates, rollback, and checks. ### Claude Desktop: install the MCPB (no Node.js needed) 1. Open the [latest GitHub release](https://github.com/drzamarian/n8n-mcp-community/releases/latest). 2. Download the file that ends in `.mcpb`. 3. In Claude Desktop, open **Settings → Extensions → Advanced settings → Install Extension…**. 4. Pick the file. Enter your n8n URL, API key, and mode. [Anthropic's MCPB guide](https://support.claude.com/en/articles/10949351-getting-started-with-local-mcp-servers-on-claude-desktop) explains the same steps. Our [installation guide](https://github.com/drzamarian/n8n-mcp-community/blob/HEAD/docs/installation.md) explains how to check the download. > Install public builds only from > [npm](https://www.npmjs.com/package/n8n-mcp-community) or the > [latest GitHub release](https://github.com/drzamarian/n8n-mcp-community/releases/latest). [![Animated demo showing installation, connection, and a useful local Introspect finding](https://github.com/drzamarian/n8n-mcp-community/blob/HEAD/docs/assets/demo.gif)](docs/demo-transcript.md) [Read the demo transcript](https://github.com/drzamarian/n8n-mcp-community/blob/HEAD/docs/demo-transcript.md). ## Why this project - **Community Edition first.** The release surface is designed for self-hosted n8n Community Edition, without presenting paid-only capabilities as available. - **44 useful tools, one explicit contract.** Every tool has bounded inputs, documented side effects, MCP safety annotations, and contract tests. - **Safe by default.** Read-only mode is the default. You choose when to allow writes or the full tool set. - **Deterministic Introspect.** `n8n_introspect` runs a local 23-rule engine; it does not execute workflows, call an agent, or contact an external model. - **Surgical node updates.** `n8n_update_node` changes one validated node path while preserving the rest of the workflow and disclosing the Public API's non-atomic limitation. - **Truthful discovery.** `n8n_list_node_types` reports only types observed in accessible workflows. It does not claim to be a complete installed catalog. - **Data minimization.** Credential values, raw execution values, pin data, and static workflow data are not returned by the generic public tools.
See verification evidence ## Current verification The current source candidate has been verified with: - exactly **44 tools**, **5 resources**, and **4 prompts** over real stdio; - **313 passing tests** locally on Node.js 24.19.0; CI and release gates require the pinned Node.js 22.23.1 and 24.18.0 matrix; - zero findings from Gitleaks, Semgrep, Trivy, and both project-root production/full `npm audit` runs; all three source scanners are reproduced in CI, with immutable scanner/action identities; - a separate no-override consumer install that resolves the patched `@hono/node-server` 2.x line, requires a zero-finding production audit, and proves the stdio runtime and exact 44/5/4 inventory; - a reproducible dependency-license gate covering 224 installed package paths; - bounded same-origin HTTP contracts and zero-request policy-denial tests; - all 44 compiled tool lifecycles on disposable n8n Community 2.30.5 and 2.30.7 instances with egress isolation, revoked keys, cleanup, and zero residue; and - a reviewed offline npm-tarball installation under the project's committed dependency policy, plus a byte-reproducible unsigned MCPB with the same compiled runtime and complete production dependency notices. Publication proceeds only through the reviewed release procedure: the repository-pinned MCPB signing identity, a human artifact-baseline receipt, tag-scoped protected-environment approval, and an externally signed MCPB handoff verified byte for byte against the reviewed unsigned candidate.
## Safety modes | Mode | What it allows | Required configuration | | --------- | --------------------------------------------------------------- | ------------------------------------ | | Read-only | Read-only tools only | Default, or `N8N_MCP_MODE=read-only` | | Write | Read-only and ordinary mutation tools | `N8N_MCP_MODE=write` | | Unsafe | All tools, including destructive or external-contact operations | `N8N_MCP_MODE=unsafe` | Selecting unsafe mode is the complete server-side authorization gate for unsafe tools. MCP safety annotations remain accurate so compatible clients can apply their native approval UX, and the n8n API key remains the final upstream permission boundary. Plain HTTP is accepted automatically only for loopback URLs. A non-loopback HTTP instance additionally requires `N8N_ALLOW_INSECURE_HTTP=1`, which accepts the risk of exposing the API key and data in transit. ## Tool catalog Every entry links to its complete input, output, endpoint, compatibility, failure, and security reference. ### Workflows | Tool | Mode | Purpose | | ---------------------------------------------------------------------- | --------- |

`n8n://node-docs/if` Four prompts guide safe workflow creation, debugging, optimization, and credential management: `create-workflow`, `debug-workflow`, `optimize-workflow`, and `manage-credentials`. ## Security model in one minute - The server uses local stdio; it does not expose an inbound HTTP listener. - Connected requests are same-origin and limited to the configured n8n host. - Redirects are rejected; request and response bodies are bounded to 2 MiB. - Generic output is validated, sanitized, bounded to 256 KiB, and wrapped as `{ "data": ..., "redacted": boolean, "untrusted": true }`. - Raw credential values and generic execution payload values are never returned. - `n8n_introspect` uses fixed local rules and has no external-model code path. - Security controls reduce risk; they do not make untrusted n8n content safe to execute or authorize broader API-key permissions.
