MCP quick start

Start with the standard initialize request.

MCP uses JSON-RPC over Streamable HTTP. After initialization, list the available tools and call only the public price, report, coverage, or methodology reads exposed by the server. Client compatibility is not guaranteed.

curl 'https://livestockmarketprices.com/mcp' \
  --header 'Content-Type: application/json' \
  --header 'Accept: application/json, text/event-stream' \
  --data '{"jsonrpc":"2.0","id":"lmp-1","method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"lmp-example","version":"1.0.0"}}}'

Response and cache behavior

Successful public responses identify the dataset release and expose an ETag. Send If-None-Match to revalidate cached data. Errors use a structured code, customer-safe message, and request ID. Price pages are limited to 100 records per request.

Citation object

Published-data and member calculation responses identify the canonical LMP page, primary-source URL, market, sale date, report revision, dataset release, unit, statistic type, and methodology version as applicable to that response.
