How to: LangChain ZeroStart Paid Service Tools content-diff

client:LangChain transport:streamable-http tool:content-diff

Add ZeroStart Paid Service Tools 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({
        "zerostart-agent": {
            "transport": "streamable_http",
            "url": "https://zerostart-agent.jack-labs.workers.dev/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that ZeroStart Paid Service Tools'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 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.
