LangChain Webhook Toolkit get_webhook_request

How to: LangChain Webhook Toolkit get_webhook_request

client:LangChain transport:streamable-http tool:get_webhook_request

Add Webhook Toolkit 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({
        "webhook-toolkit": {
            "transport": "streamable_http",
            "url": "https://webhook-toolkit.com/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Webhook Toolkit'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

Set these first

Webhook Toolkit will not start until these are set, so get_webhook_request never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 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.
