LangChain Magicalink by AgentTransmit transmit_ack

How to: LangChain Magicalink by AgentTransmit transmit_ack

client:LangChain transport:streamable-http tool:transmit_ack

Add Magicalink by AgentTransmit 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({
        "magicalink": {
            "transport": "streamable_http",
            "url": "https://mcp.agenttransmit.com/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Magicalink by AgentTransmit'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.
