Problem with MCP n8n

Support Bug Reports

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Hello. I’ve enabled n8n-mcp in mcp.json, but Cursor can’t call tools through it.

Cursor itself describes this as “The n8n-mcp MCP server is enabled, but the agent doesn’t see the server and can’t call get_node.”

Steps to Reproduce

Enable the n8n-mcp MCP server in the Cursor settings (Settings → MCP → n8n-mcp, switch to the “on” position). Open a chat with the agent (Agent / Composer). In the chat, ask the agent to call a tool from n8n-mcp, for example: “Call get_node from n8n-mcp for nodeType n8n-nodes-base.httpRequest” or ask to list the resources of the MCP server “n8n-mcp”. Review the agent’s response. Expected: The agent calls n8n-mcp tools (for example, get_node) or at least sees the server. Actual: The agent reports that the server is not found (for example, Server “n8n-mcp” not found when trying to access it), n8n-mcp tools are not available in the chat.

Expected Behavior

Correct call to tools when running n8n-mcp
