DepthFeed MCP

An official MCP server operated by DepthFeed that enables AI agents to retrieve live and historical order-book depth data for prediction markets such as Polymarket, Kalshi, and Limitless. It provides tools for market search, snapshot retrieval, and order book access via a Streamable HTTP endpoint.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

DepthFeed serves prediction-market order-book depth and history for Polymarket, Kalshi, and Limitless across BTC/ETH/SOL/XRP/DOGE/BNB/HYPE up/down markets. Paid data plans can use polymarket_all_markets for the complete current Polymarket universe in a compact MARKET_NAME | PRICE | DEADLINE format. Then use the *_search_markets tools or the returned market ids to inspect depth and history with *_get_orderbook / *_get_snapshots tools for live and historical depth; `screener` gives a cross-venue top-of-book view. Without an API key you are on the keyless demo tier (BTC + Polymarket, top-of-book only). Set a DepthFeed API key (Authorization: Bearer df_…, from https://depthfeed.com) to unlock all coins, Kalshi, Limitless, the full ladder, and deep history. Timestamps accept ms-epoch or ISO-8601.

polymarket_all_markets

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

Paid data plan required. Return every active Polymarket market across all categories, not only crypto. AI execution credits do not unlock this export. The text result is one LLM-readable line per market: MARKET_NAME | OUTCOME PRICES | DEADLINE | MARKET_ID. The sweep fails closed if complete pagination cannot be verified and includes timestamp, count, source-page count, and SHA-256.

bars

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

OHLCV price bars for US equities and ETFs, Binance spot pairs, and perpetual futures. One minute is the finest resolution; 5Min, 15Min, 1Hour and 1Day are rolled up from it and say so with `derived`. Spell a crypto pair the way the venue does (BTCUSDT, not BTC) and a perpetual with a .P suffix (BTCUSDT.P) — spot and perp are different instruments at different prices. BTCU, ETHU and WLDU are each both a US ETF and a Binance pair, and resolve to the equity — pass venue=binance to reach the pair instead. Optional `venue` selects the market explicitly: us-equities, binance (spot) or binance-futures (perpetuals). Bounded by the same plan history window as every other read (403 HISTORY_LIMIT_EXCEEDED past it); the plan also sets how many symbols one request may carry.

backtest_paths

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

Mid-price path per Polymarket market for backtesting, resampled to a fixed interval and bounded to each market's own lifetime so post-settlement books cannot leak in as risk-free fills. Returns {interval_seconds, markets:{<market_id>:{points:[[ts_ms, price_up, coin_price], …]}}} — up to 1000 points per market. Pass 1 to 50 market ids from polymarket_search_markets. History is bounded by the plan window and the interval floor by plan; both fail closed rather than silently coarsening.

A lightweight connection check about every six hours, sampled on hosts with many listings. It shows the server answered, not that its tools work.

Too few checks for a percentage yet (2 of 2 answered).

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http depthfeed-mcp https://api.depthfeed.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add depthfeed-mcp --url https://api.depthfeed.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable depthfeed-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "depthfeed-mcp": {
      "url": "https://api.depthfeed.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "depthfeed-mcp": {
      "type": "streamableHttp",
      "url": "https://api.depthfeed.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start depthfeed-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "depthfeed-mcp": {
      "type": "http",
      "url": "https://api.depthfeed.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http depthfeed-mcp https://api.depthfeed.com/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Claude Desktop configuration

https://api.depthfeed.com/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "depthfeed-mcp": {
      "serverUrl": "https://api.depthfeed.com/mcp"
    }
  }
}
