LangChain eia energy mcp server eia_browse_routes

How to: LangChain eia energy mcp server eia_browse_routes

client:LangChain transport:streamable-http tool:eia_browse_routes

Add eia energy mcp server 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({
        "eia-energy-mcp-server": {
            "transport": "streamable_http",
            "url": "https://eia-energy.caseyjhand.com/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that eia energy mcp server'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

eia energy mcp server will not start until these are set, so eia_browse_routes never becomes available.

  • EIA_API_KEY
  • EIA_DATASET_TTL_SECONDS
  • EIA_DATAFRAME_DROP_ENABLED
  • EIA_CANVAS_MAX_ROWS
  • EIA_FACET_VALUE_CAP
  • CANVAS_PROVIDER_TYPE
  • MCP_LOG_LEVEL

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.
