LangChain Parallax Protocol network_trends

How to: LangChain Parallax Protocol network_trends

client:LangChain transport:streamable-http tool:network_trends

Add Parallax 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({
        "parallax-mcp": {
            "transport": "streamable_http",
            "url": "https://mcp.parallaxprotocol.org/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Parallax 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

Parallax Protocol will not start until these are set, so network_trends never becomes available.

  • PARALLAX_MCP_RPC_URL
  • PARALLAX_MCP_GROUPS

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 13 October 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.
