② Call a Tool
Ask your AI assistant to call a specific tool, or send raw JSON-RPC:
Natural Language Prompt
“Use the _ping tool to verify n8n api connectivity by fetching instance owner info. used internally by aerostack to validate credentials”
Using a Workspace?
Add this MCP to your Workspace — your team shares one token, secrets are stored securely, and every AI agent in the workspace can call it without per-user setup.
List, trigger, and manage n8n workflows — execute automations, check execution status, and manage credentials from any agent.
n8n is the open-source workflow automation platform that connects hundreds of services. This MCP server gives your AI agents the ability to list workflows, trigger executions with input data, monitor execution status, and inspect credentials and tags — making n8n a powerful automation backend for any AI-driven workflow.

The n8n REST API must be enabled on your instance.
Self-hosted n8n:
Set the environment variable N8N_PUBLIC_API_ENABLED=true (enabled by default on most installations).
n8n Cloud:
The API is enabled by default. Go to Settings → API to verify.

| Error | Cause | Fix |
|---|---|---|
n8n API 401 | Invalid or expired API key | Generate a new API key in n8n Settings → API |
n8n API 403 | API key lacks permissions | Ensure the API key owner has admin access |
n8n API 404 | Wrong base URL or workflow ID doesn't exist | Verify N8N_API_URL points to your n8n instance (not a subpath) |
fetch failed | n8n instance is unreachable | Verify your n8n instance is running and accessible from the internet |
Missing N8N_API_URL secret | Secret not configured in Aerostack | Add N8N_API_URL to your workspace secrets |

N8n MCP exposes the following tools to your AI agent: `_ping`, `list_workflows`, `get_workflow`, `activate_workflow`, `deactivate_workflow`. Use these to automate n8n workflows directly from Claude, Cursor, or any MCP-compatible client.
Add the following to your Claude Desktop config (`claude_desktop_config.json`): ```json { "mcpServers": { "@aerostack/mcp-n8n": { "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-n8n"] } } } ``` Then restart Claude Desktop and the tools will appear automatically.
In Cursor, open **Settings → MCP** and add: ```json { "name": "@aerostack/mcp-n8n", "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-n8n"] } ``` Save and reload Cursor. The MCP tools will be available in Agent mode.
Yes. N8n requires authentication. Check the MCP's documentation for the required credentials.
