How do I use MCP within my graph in studio?

[Idotr1997]

Because we are making a Async graph when using MCP sse transport LangGraph studio can't use the graph.

how are you defining your graph? how does your langgraph.json look like? what exactly is not working in langgraph studio?

[Idotr1997]

I export the graph as usual i used in the studio many times and worked well until now when using the changes MCP SSE requires.
other agents work for me also i using it as sub_graph and it seems like a simple node, while other agent is working well and as expected.

is this how you are defining your pr manager graph? https://github.com/langchain-ai/langchain-mcp-adapters/tree/main?tab=readme-ov-file#using-with-langgraph-api-server

[Idotr1997]

no it is way to simplified.

[Idotr1997]

also you use load_mcp_tools in MultiServerMCPClient

Going to convert to a discussion since, without a concrete description of the problem or code snippet, this sounds like an issue in how you've defined your graph.

still not clear how can we use langgraph studio on agent using MCP SSE tools.
