How to: LangChain Willo MCP by usefulapi willo_list_interviews

client:LangChain transport:streamable-http tool:willo_list_interviews

Add Willo MCP by usefulapi to LangChain

  1. 01

    Open pip install langchain-mcp-adapters and merge this in. Keep any servers already there.

from langchain_mcp_adapters.client import MultiServerMCPClient

client = MultiServerMCPClient({
        "willo": {
            "transport": "streamable_http",
            "url": "https://willo.usefulapi.io/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

    Ask for something willo_list_interviews does. LangChain lists the server's tools on connect and calls willo_list_interviews itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Willo MCP by usefulapi's identifier in your config matches the one above exactly.

get_tools() returns the server's tools as LangChain tools, ready for an agent. LangChain docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 14 November 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
