How to: LangChain PropLine — Sports Betting Odds & Prop Resolution propline_create_free_api_key

client:LangChain transport:streamable-http tool:propline_create_free_api_key

Add PropLine — Sports Betting Odds & Prop Resolution 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({
        "propline-mcp": {
            "transport": "streamable_http",
            "url": "https://mcp.prop-line.com/mcp",
        }
})

tools = await client.get_tools()
  1. 02

    Save the file and restart LangChain.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that PropLine — Sports Betting Odds & Prop Resolution'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

PropLine — Sports Betting Odds & Prop Resolution will not start until these are set, so propline_create_free_api_key never becomes available.

  • PROPLINE_API_KEY
  • PROPLINE_BASE_URL

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.
