dino-markets-mcp

Stdio bridge for dino.markets — matched Kalshi + Polymarket prediction-market data for AI agents. The same event matched across both venues, cross-venue spreads, and confirmed arbitrage sized to fillable depth, for Claude, Cursor, and any MCP (Model Context Protocol) client. Market data only — not a broker; not financial advice.

Thin proxy: the bridge holds no tool definitions or schemas. Every tool is served live from the api.dino.markets HTTP MCP endpoint, so descriptions and schemas are always up to date.

Prefer a remote connection? The server also runs directly at https://api.dino.markets/v2/mcp/ (streamable HTTP) and is listed in the official MCP registry as markets.dino/mcp — no install needed:

claude mcp add --transport http dino-markets https://api.dino.markets/v2/mcp/
