Lantern Works deals — MCP server (read-only, stdio)

mcp-name: io.github.connormatthewdouglas/lantern-works-deals

Free, read-only, no API key. Search and compare AI-infra deals and free tiers, and compare tracked GPU rental prices, ranked by customer value (never by affiliate status).

Quick start

uvx lantern-works-deals-mcp

Claude Code:

claude mcp add lantern-works-deals -- uvx lantern-works-deals-mcp

Claude Desktop (claude_desktop_config.json) / Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "lantern-works-deals": {
      "command": "uvx",
      "args": ["lantern-works-deals-mcp"]
    }
  }
}

Without uv: pip install lantern-works-deals-mcp, then use "command": "lantern-works-deals-mcp". Docker: docker build -t lantern-works-deals-mcp . && docker run -i --rm lantern-works-deals-mcp. More clients: https://thelanternworks.com/install/

Tools

compare_gpu_prices uses exactly the data published at https://thelanternworks.com/api/v1/gpu-prices.json. Model matching is by whole tokens (H100 matches H100 SXM; L40 does not match L40S). "Cheapest" means cheapest among tracked providers, not the whole market.

Errors: {"error": {"code": "invalid_argument|invalid_cursor|not_found|feed_unavailable|feed_invalid", "message": ...}}.

Data and privacy

Deals: https://thelanternworks.com/api/v1/deals.json; GPU prices: https://thelanternworks.com/api/v1/gpu-prices.json. Each is cached 5 min (a stale copy is served if a refetch fails). Requests send only User-Agent: lantern-works-deals-mcp/<version> (no user, host or install identifiers). Overrides: LANTERN_DEALS_FILE / LANTERN_DEALS_URL, LANTERN_GPU_PRICES_FILE / LANTERN_GPU_PRICES_URL. Only an allow-list of public fields is returned.
