LangChain byte protocol byte_buy_data

How to: LangChain byte protocol byte_buy_data

client:LangChain transport:streamable-http tool:byte_buy_data

Add byte protocol 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({
        "byte-protocol": {
            "transport": "streamable_http",
            "url": "https://mcp.payperbyte.io/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that byte protocol'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

byte protocol will not start until these are set, so byte_buy_data never becomes available.

  • RPC_URL
  • BYTE_GATEWAY_ATTESTER

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.
