Tools (10)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • cancel

    Cancel ticket(s). Provide exactly one of: ticket_id (one ticket), symbol (all tickets for that symbol), or all=True (every active ticket). Returns {"canceled": <n>} for symbol/all, {"canceled": null} for a single ticket_id (no count) or on failure.

  • instruments

    List supported instruments per configured exchange whose native symbol contains `symbol` (case-insensitive). Use the returned `symbol` field as the exact value to pass to `place` (e.g. binance-futures `DOGEUSDT`, okx-swap `DOGE-USDT-SWAP`). No credentials needed — public data.

  • nav

    Net Asset Value across all running executors: {exchanges:[{exchange, nav, wallet_balance, margin_value, unrealized_pnl}], total_nav, exchanges_queried}. NAV = wallet + margin (USD) + unrealized PnL.

  • open_orders

    Currently active (NEW/OPEN) orders on each configured exchange. Useful to debug "ticket OPEN but executed=0" — confirms the strategy actually placed orders on the venue. Returns `{"count": <n>, "open_orders": [...]}` — matches the CLI `blockfill check open-orders` envelope.

  • place

    Place an execution ticket to reach `target_position` (signed; the daemon computes the delta from the current position and slices orders to hit the target within the time window). THIS PLACES REAL ORDERS on a live exchange. Confirm exchange/symbol/size with the user before calling. Args: exchange: e.g. "binance-futures", "okx-swap", "hyperliquid-perp". symbol: native venue symbol — use `instruments(symbol)` to get it. target_position: signed target position size (base units). strategy: "maker" (default) or "twap". time_constraint_ms: execution window, 60_000–86_400_000 (1 …

  • positions

    Current exchange positions across all running executors. Each entry: {exchange, symbol, size, entry_price, update_ts_ms}. Returns `{"count": <n>, "positions": [...]}` — a single object (not a bare list) so the MCP result is one coherent JSON, consistent with `query`.

  • query

    List tickets. history=False (default) = active-session in-memory state; history=True = persistent history across all sessions. Filter by status (NEW/OPEN/FILLED/CANCEL/...), symbol, or ticket_id. Returns `{"count": <n>, "tickets": [...]}` — the same envelope as the CLI `blockfill ticket query`, so CLI and MCP output are byte-identical.

  • quota

    x402 quota for CEX accounts: free tickets remaining + paid quota_balance. Pass an exchange to scope to one account; omit for all configured CEX. `free_remaining == -1` means quota is disabled on the server (unlimited). Returns `{"count": <n>, "quota": [...]}` — always a list (even with an exchange), matching the CLI `blockfill quota` envelope.

  • status

    Daemon health and per-exchange readiness. Returns running / pid / version / configured exchanges / ready_exchanges / active_tickets / uptime / proxy. Call this first to confirm the daemon is up and which exchanges can trade.

  • tca

    Transaction cost analysis per ticket: benchmarks (l1/mid/twap/vwap), fills, maker/taker breakdown, execution & opportunity cost (USD). history=False = finalized TCA from the active session; history=True = persistent TCA across sessions. Returns `{"count": <n>, "tca": [...]}` — mirrors the `{count, tickets}` envelope used by `query` for consistency across list-returning tools.
