Names are unique per user. What if we added the id like name ({id})?

Anthropic released model context protocol a few days ago https://modelcontextprotocol.io/introduction
It's an open protocol for LLM applications (first one being the claude desktop ui) and external data sources and tools. In this integration, any flow in langflow becomes a tool in mcp and can be accessed directly by claude from claude desktop. Here's a screenshot from mcp inspector https://github.com/modelcontextprotocol/inspector
This pull request introduces the integration of the
mcpmodule into the project. The changes include adding themcpdependency, updating the API routing to includemcp, and implementing themcpserver functionality.Key changes include:
