For agents: Claude Code's command for the MCP server.

Test app · session Oct 6

One take. A recorded Claude Code prompt asks TradingFlow over MCP to rank SPY contracts by premium for October 6, 2026, and the reply's three rows stream in. A window lands around the reply and it becomes the Contract Rank page, the $655 put still lit in the same place: #2 by premium. A pointer opens the put's 64 trades: $61.3M of its $62.4M traded at the mid. The in-app TradingFlow AI answers a question about the same put on the same page: open interest moved by 2 contracts. A click on SPY opens its Symbol view on the Flow tab, $2.05B of premium that session; a click on the GEX tab opens the gamma structure, its put wall at $770. The Ticker Options Snapshot recipe runs for SPY and its six figures drop in. Premium, trades, the open-interest change and the put wall line up over the TradingFlow logo and the trial line. For humans. And their agents. Read-only by default. We do not trade for you.

    Bring your agent

    Claude Code, Cursor, Codex or OpenClaw query the same tables through MCP.

    Set up MCP

  1. Read the tape.

    Every print as it hits the tape: side, strike, premium, size and open interest in one row, with the session and date attached, so the move can be checked print by print.

  2. Rank the money.

    Symbols and contracts ranked by premium for the session, with flow direction, Vol/OI and IV rank beside them, so the one put that took $62.4M stands out from the noise.

  3. See positioning take shape.

    Net GEX and open interest by strike, the walls and the spot on one chart, read as context for the tape rather than as a target.

  4. The same data, for agents.

    Ask TradingFlow AI about the page, build and edit recipes with it, or connect your own agent through MCP. Read-only by default; it cannot send an order.
