README
n8n MCP Server
MCP Server untuk n8n REST API, dibangun dengan FastMCP. Ekspos tool untuk mengelola workflows, executions, credentials, tags, dan variables langsung dari MCP client (Claude Desktop, Claude Code, Claude Web).
Dipakai lewat tiga kanal: stdio, Claude Code, dan Claude Web (claude.ai). Otentikasi memakai Authentik sebagai identity provider (untuk Claude Web).

Cara pakai per kanal
1. stdio — Claude Desktop / Claude Code lokal
Tidak perlu auth jaringan; client men-spawn proses langsung.
{
"mcpServers": {
"n8n-mcp": {
"command": "uvx",
"args": ["--from", "git+https://github.com/andhit-r/n8n-mcp@v0.1.0", "n8n-mcp"],
"env": {
"N8N_API_BASE_URL": "http://localhost:5678/api/v1",
"N8N_API_KEY": "your-n8n-api-key"
}
}
}
}
Atau via Docker (stdio):
{
"mcpServers": {
"n8n-mcp": {
"command": "docker",
"args": [
"run", "--rm", "-i",
"-e", "MCP_TRANSPORT=stdio",
"-e", "N8N_API_BASE_URL=http://host.docker.internal:5678/api/v1",
"-e", "N8N_API_KEY=your-n8n-api-key",
"ghcr.io/andhit-r/n8n-mcp:latest"
]
}
}
}
2. Claude Code
# stdio (langsung, tanpa server terpisah)
claude mcp add n8n-mcp -- uvx --from "git+https://github.com/andhit-r/n8n-mcp@v0.1.0" n8n-mcp
# remote (server HTTP yang sudah berjalan)
claude mcp add --transport http n8n-mcp https://n8n-mcp.example.com/mcp
3. Claude Web (claude.ai) — remote, WAJIB OAuth Authentik
Jalankan server sebagai service HTTP di URL publik HTTPS, daftarkan sebagai Custom Connector di claude.ai.
docker run -d -p 8000:8000 \
-e N8N_API_BASE_URL=https://your-n8n.example.com/api/v1 \
-e N8N_API_KEY=your-n8n-api-key \
-e MCP_BASE_URL=https://n8n-mcp.example.com \
-e AUTHENTIK_BASE_URL=https://auth.example.com \
-e AUTHENTIK_APP_SLUG=n8n-mcp \
-e AUTHENTIK_CLIENT_ID=... \
-e AUTHENTIK_CLIENT_SECRET=... \
ghcr.io/andhit-r/n8n-mcp:latest
Dirilis via GitHub (GitHub Release + image GHCR). Tidak tersedia di PyPI. Install dari sumber:
pip install "git+https://github.com/andhit-r/n8n-mcp@v0.1.0".
Konfigurasi n8n API
Aktifkan Public REST API di n8n: Settings → n8n API → Create an API key. Pastikan akun memiliki izin yang sesuai (admin direkomendasikan).
| Variabel | Wajib | Contoh |
|---|---|---|
N8N_API_BASE_URL |
Ya | http://localhost:5678/api/v1 |
N8N_API_KEY |
Ya | n8n_api_xxx... |
N8N_TIMEOUT |
Tidak | 30 (detik, default) |
Otentikasi (Authentik)
Server memilih auth otomatis dari environment:
| Mekanisme | Untuk | Aktif jika |
|---|---|---|
| OAuth Authentik | Claude Web / browser | AUTHENTIK_* + MCP_BASE_URL diisi |
| API Key statis | VS Code / CLI | MCP_API_KEY diisi |
| (tanpa auth) | stdio / jaringan lokal | tidak ada yang diisi |
Buat OAuth2/OIDC Provider + Application di Authentik (Redirect URI
https://<MCP_BASE_URL>/auth/callback, scope openid profile email).
Transport (environment)
| Variabel | Default | Keterangan |
|---|---|---|
MCP_TRANSPORT |
stdio |
stdio, http, atau sse |
MCP_HOST / MCP_PORT |
127.0.0.1 / 8000 |
bind saat http/sse |
MCP_BASE_URL |
— | URL publik (wajib untuk OAuth Authentik) |
Deployment cloud: uvicorn n8n_mcp.asgi:app --host 0.0.0.0 --port 8000.
Pengembangan
pip install -e .
cp .env.example .env # isi N8N_API_BASE_URL dan N8N_API_KEY
python -m n8n_mcp # jalankan lokal (stdio)
make test # gate test (lint + unit)
Lisensi
