LangChain Jhtdb jhtdb_point_query

How to: LangChain Jhtdb jhtdb_point_query

client:LangChain transport:streamable-http tool:jhtdb_point_query

Add Jhtdb 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({
        "jhtdb": {
            "transport": "streamable_http",
            "url": "https://gateway.pipeworx.io/jhtdb/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Jhtdb'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 20 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.
