Dokümantasyon

The DepthFeed MCP server is a remote Streamable-HTTP endpoint (https://api.depthfeed.com/mcp) that exposes Polymarket, Kalshi, and Limitless order-book data as Model Context Protocol tools. AI agents call tools like polymarket_search_markets and kalshi_get_orderbook to fetch live and historical depth as JSON, with the same plan gating as the REST API.

What the MCP server gives your agent

  1. Keyless to start, your key for everything

    Add the endpoint with no key and your agent is on the demo tier — BTC Polymarket markets, top-of-book — so a one-click install works the moment it lands. Add a DepthFeed API key (Authorization: Bearer df_…) and the same session unlocks all 7 assets, Kalshi, Limitless, the full ladder, and deep history. Paid-only calls return a clear in-tool message, not an error, so the agent knows exactly what to upgrade.

  2. Eleven read-only tools across three venues

    Discovery and depth in one toolset: polymarket_search_markets / kalshi_search_markets / limitless_search_markets to find a market, then *_get_orderbook for the latest book and *_get_snapshots for history, plus screener for a cross-venue top-of-book view and whoami to read the session's plan. Every tool is read-only and exposes the same underlying DepthFeed records through tool-specific response envelopes.

  3. Add it to Claude, Cursor, Codex, or ChatGPT

    In Claude Code: `claude mcp add --transport http depthfeed https://api.depthfeed.com/mcp\`. In Cursor, VS Code, Claude Desktop, ChatGPT (Developer Mode), and OpenAI Codex, add the same URL as a custom/remote MCP server. Because it is a standard remote MCP endpoint, any MCP-capable client works — copy-paste snippets and one-click buttons are in the docs.
