Hi, I added this to my cursor MCP:

    "langgraph-docs-mcp": {
      "command": "uvx",
      "args": [
        "--from",
        "mcpdoc",
        "mcpdoc",
        "--urls",
        "LangGraph:https://langchain-ai.github.io/langgraph/llms.txt",
        "--urls",
        "LangChain:https://python.langchain.com/llms.txt",
        "--transport",
        "stdio"
      ]
    }

However, if I ask the Agent, "call the list_doc_sources mcp tool", it returns this:

So it looks like it is only using the second URL. Are the URLs specified incorrectly?

This format seems to work instead:

    "langgraph-docs-mcp": {
      "command": "uvx",
      "args": [
        "--from",
        "mcpdoc",
        "mcpdoc",
        "--urls",
        "LangGraph:https://langchain-ai.github.io/langgraph/llms.txt,LangChain:https://python.langchain.com/llms.txt",
        "--transport",
        "stdio"
      ]
    }

I encountered a similar issue...

I used this in the cli to get it to work when optionally testing:

uvx --from mcpdoc mcpdoc \
    --urls "LangGraph:https://langchain-ai.github.io/langgraph/llms.txt" "LangChain:https://python.langchain.com/llms.txt" \
    --transport sse \
    --port 8082 \
    --host localhost

and

{
  "mcpServers": {
    "langgraph-docs-mcp": {
      "command": "uvx",
      "args": [
        "--from",
        "mcpdoc",
        "mcpdoc",
        "--urls",
        "LangGraph:https://langchain-ai.github.io/langgraph/llms.txt LangChain:https://python.langchain.com/llms.txt",
        "--transport",
        "stdio"
      ]
    }
  }
}

@larsenweigle thanks for the fix.

The correct syntax is:

"--urls",
"LangGraph:https://langchain-ai.github.io/langgraph/llms.txt LangChain:https://python.langchain.com/llms.txt",

@eyurtsev commented on GitHub (Apr 5, 2025): @larsenweigle thanks for the fix. The correct syntax is: ```shell "--urls", "LangGraph:https://langchain-ai.github.io/langgraph/llms.txt LangChain:https://python.langchain.com/llms.txt", ```
