# DepthFeed MCP Server **Give Claude, Cursor, Codex, and ChatGPT live prediction-market order-book data.** [DepthFeed](https://depthfeed.com) runs a remote [Model Context Protocol](https://modelcontextprotocol.io) (MCP) server so AI agents can pull **Polymarket, Kalshi, and Limitless** order-book depth and price data straight into a session — no SDK, no glue code. Listed in the official MCP registry as [`com.depthfeed/depthfeed`](https://registry.modelcontextprotocol.io/v0.1/servers?search=com.depthfeed/depthfeed). ``` https://api.depthfeed.com/mcp ``` It's a **remote, Streamable-HTTP** server and **keyless to start**: add the endpoint and your agent can query BTC Polymarket markets immediately. Add a [DepthFeed API key](https://depthfeed.com) (`Authorization: Bearer df_…`) to unlock all 7 assets (BTC/ETH/SOL/XRP/DOGE/BNB/HYPE), Kalshi, Limitless, the full order-book ladder, and deep history — the same plan gating as the REST API. ## Install **Claude Code** ```bash claude mcp add --transport http depthfeed https://api.depthfeed.com/mcp # with a key: claude mcp add --transport http depthfeed https://api.depthfeed.com/mcp \ --header "Authorization: Bearer df_YOURKEY" ``` **Cursor** — `~/.cursor/mcp.json` (or `.cursor/mcp.json`) ```json { "mcpServers": { "depthfeed": { "url": "https://api.depthfeed.com/mcp" } } } ``` **VS Code (Copilot agent mode)** ```bash code --add-mcp '{"name":"depthfeed","type":"http","url":"https://api.depthfeed.com/mcp"}' ``` **Claude Desktop** — Settings → Connectors → Add custom connector → paste the URL. **ChatGPT** — Settings → Connectors → enable Developer Mode → add the URL. **OpenAI Codex** — `~/.codex/config.toml` ```toml [mcp_servers.depthfeed] url = "https://api.depthfeed.com/mcp" # bearer_token_env_var = "DEPTHFEED_TOKEN" # optional, for a key ``` Any MCP-capable client works (Windsurf, Cline, Zed, …) — add `https://api.depthfeed.com/mcp` as a remote/custom MCP server. ## Tools All tools are **read-only** and return the same JSON as the [DepthFeed REST API](https://depthfeed.com/docs). | Tool | Returns | |---|---| | `polymarket_all_markets` | All currently discoverable Polymarket markets across supported assets | | `polymarket_search_markets` | Polymarket up/down crypto markets for a coin | | `polymarket_get_market` | A single Polymarket market by id or slug | | `polymarket_get_snapshots` | Polymarket order-book history (time series) | | `kalshi_search_markets` | Kalshi crypto markets *(paid)* | | `kalshi_get_orderbook` | Latest Kalshi yes/no depth by ticker *(paid)* | | `kalshi_get_snapshots` | Kalshi yes/no depth history *(paid)* | | `limitless_search_markets` | Open Limitless markets on Base *(paid)* | | `limitless_get_orderbook` | Latest Limitless L2 depth by slug *(paid)* | | `limitless_get_snapshots` | Limitless L2 depth history *(paid)* | | `screener` | Cross-venue top-of-book snapshot for all assets | | `whoami` | The session's plan, limits, and coin access | ## Live example (no key) ```bash # List tools curl -sS https://api.depthfeed.com/mcp -H 'content-type: application/json' \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' # Keyless BTC Polymarket markets curl -sS https://api.depthfeed.com/mcp -H 'content-type: application/json' \ -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"polymarket_search_markets","arguments":{"coin":"btc","limit":3}}}' ``` ## Links - Website: <https://depthfeed.com> - MCP landing page: <https://depthfeed.com/mcp> - Guide: <https://depthfeed.com/resources/prediction-market-mcp-server> - API docs: <https://depthfeed.com/docs> - Python clients: [polymarket-price-data](https://github.com/vcorp-dev/polymarket-price-data) · [kalshi-price-data](https://github.com/vcorp-dev/kalshi-price-data) ## Contributing and support - Propose documentation or integration improvements in [CONTRIBUTING.md](./CONTRIBUTING.md). - Ask usage questions through [DepthFeed support](https://depthfeed.com/contact). - Report security concerns privately using [SECURITY.md](./SECURITY.md). --- Independent research project.
