Provide and use Model Context Protocol

The idea is:

Anthropic published a new spec for AI to discover available tools via their model context protocol.

Model Context Protocol (MCP) is an open protocol that enables seamless integration between LLM applications and external data sources and tools. Whether you’re building an AI-powered IDE, enhancing a chat interface, or creating custom AI workflows, MCP provides a standardized way to connect LLMs with the context they need.

Let n8n:

  • consume MCP servers via JSON-RCP
  • act as a MCP server for other workflows or other consumers

My use case:

I think it would be beneficial to add this because:

Instead of tools needing to be known at the time of building workflows, the amount of tools available to a consumer is contingent to a context provider evolving.

This means, if n8n AI nodes could leverage MCP, the efficiency and ways to solve problems with AI could progressively be enhanced.

Any resources to support this?

Are you willing to work on this?

kinda :slight_smile:

I had the same idea :smiley:

In the future, I imagine that instead of building all the “tools” by itself, n8n will interact with “tools” by using MCP. That way it can leverage the existing works of others

That is a great idea. Integrating with MCP servers will definitely leverage AI automations more!

Let me share another idea related to MCP server, aside from MCP servers as tools.

If a n8n workflow acts as a MCP server, we can integrate our own custom AI-powered tools with n8n. Sometimes, it would be great to implement a custom AI-powered app for internal use of companies. If we leverage n8n outside of the platform in custom AI tools, that would be awesome.

The other benefit to n8n is that this opens up the entire world of existing MCP servers to be AI plugins into n8n, without having to write any code other than the MCP client integration. Check out directories of MCP servers like https://mcp.so/ and Open-Source MCP servers | Glama

Yes, when I learned about MCP, my first reaction was whether it could go together with n8n to build better products, so I found my way here.

Found an MCP server that’ll allow MCP clients to use n8n workflows as tools

I won’t have time to try it for at least a few days. If anyone does, pls report back :pray: :pray: :pray:

Great, I have the same idea as you
n8n urgently needs support for MCP

I just created an account on this forum to say yes we really need this. Who’s building?

I like this analogy with USB connector.
MCP is a kind of USB, a universal software connector for data, apps, file system, repositories.

I created a node for clients. I’ll work on servers next. However feel free to contribute.
