Pro MCP paired with Alpaca

Why this pairing

Confluence grades. Alpaca executes — after you confirm.

Official Alpaca MCP Server — option chain, quotes/Greeks, then place_option_order after you confirm.

Paper first

Default ALPACA_PAPER_TRADE=true until the flow is proven.

Single-leg long premium

Same Confluence delta/spread/rail rules; Alpaca places only after your confirm.

You confirm every trade

Advisory only. Never paste API keys into chat.

Session loop

Plan tool: plan_alpaca_entry · MCP: uvx alpaca-mcp-server · Auth: Local stdio via uvx alpaca-mcp-server with ALPACA_API_KEY + ALPACA_SECRET_KEY in mcp.json env.

Important: Pro MCP is advisory software only. It does not manage money, hold custody, or place trades. You confirm every order in Alpaca. 0DTE options carry substantial risk of loss. Not investment advice. Alpaca is a trademark of its respective owner; Signal Technology is independent and not affiliated with, endorsed by, or sponsored by Alpaca Securities LLC.

No Signal tool submits an order. Every order is placed and confirmed by you in your broker’s own interface or your broker’s MCP after you review it; we never auto-trade. Broker names are trademarks of their owners. Signal is not affiliated with or endorsed by any broker.
