4Runr's custom MCP Client node for n8n — connects to a self-hosted MCP server via SSE and streams tool definitions to n8n AI Agents.

Package Exports

  • n8n-nodes-mcp-client
  • n8n-nodes-mcp-client/dist/nodes/McpClient/McpClient.node.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (n8n-nodes-mcp-client) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

n8n-nodes-mcp-client

Built by 4Runr, this is a custom n8n node that connects to a self-hosted MCP Server via Server-Sent Events (SSE). It streams tool definitions to n8n AI Agents in real time, enabling flexible, dynamic automation at scale.

Features

  • Listens to an sseUrl endpoint for incoming tools events.
  • Emits tool definitions for use in the n8n AI Agent ecosystem.
  • Logs events, handles errors, and filters events automatically.
  • Optimized for 4Runr's AI automation infrastructure and MCP server systems.

Usage

  1. Add your custom MCP server's SSE URL as a credential.
  2. Use this node as a tool source in your AI Agent configuration.
  3. Tools will auto-populate based on live MCP events.
