LangChain Parallax Protocol Prompt/audit_address

How to: LangChain Parallax Protocol audit_address

client:LangChain transport:streamable-http prompt:audit_address

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

    audit_address is surfaced through the client's prompt API, fetched by name. Unlike a tool, you invoke it deliberately — LangChain will not call it for you.

  3. 04

    If it does not appear, check that Parallax Protocol is connected and that you are looking at its prompts rather than its tools.

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 it never reaches LangChain.

Same prompt, other clients

Read from the server itself, by connecting to it and calling prompts/list on 13 October 2026. A listing does not declare its prompts, so asking is the only way to know them, and this is what the server actually offers rather than what its listing claims. Names only are stored; connect the server for each prompt's arguments.
