DEVELOPER & AGENT READY

Infrastructure for
Autonomous Trading.

REST API + MCP server + A2A agent routing + HMAC-signed webhooks + live options flow + broker execution routes. Signa is the only retail trading platform built to be consumed by AI agents autonomously. The 29-Driver Action Card, ICS, Wyckoff Phase Detection, Elliott Wave, live Unusual Whales options flow, congressional trade data, and Alpaca broker execution are all accessible programmatically.

INDUSTRY FIRST

Native MCP Server

MCP (Model Context Protocol) was released by Anthropic in late 2024. Signa is one of the first commercial platforms to implement it for a non-developer consumer audience — not just as a demo, but as a production-grade signal data source.

No other retail trading platform has built an MCP server. This means Signa is the only platform where you can ask Claude, Cursor, or any AI assistant a trading question and get a response grounded in real, live institutional-grade signal data.

This is not a chatbot wrapper. The MCP server exposes the full signal engine — screener, indicators, analysis, and Action Card — as callable tools that any AI agent can invoke.

✓Works with Claude Desktop, Cursor, Windsurf, and any MCP client

✓Exposes screener, signal, indicators, and analysis as tools

✓Real-time data — not cached or delayed

✓Requires only an API key — no code required for consumers

✓Full tool documentation included in the MCP manifest

CLAUDE DESKTOP — claude_desktop_config.json

  "mcpServers": {
    "signa": {
      "url": "https://getsigna.ai/mcp",
      "headers": {
        "Authorization":

    }
  }
}

EXAMPLE: ASK CLAUDE
You: "What are the top 3 bullish setups right now?"
Claude calls signa.screener({symbols: watchlist, filter: "bullish"}) → returns ranked results with full signal data → responds with analysis grounded in live Signa data.

BROKER EXECUTION

Alpaca Integration

Signa connects to Alpaca (paper or live) through dedicated broker API routes. Connect a user account, execute trades with Kelly Criterion position sizing, sync live positions, and retrieve positions with Signa edge recommendations — all programmatically.

Build fully autonomous trading agents that receive a Signa signal, calculate position size, execute the order, and monitor the position — without any human intervention.

✓AES-256-GCM encrypted credential storage

✓Kelly Criterion position sizing from edge score and confidence

✓Paper and live account support — switch without changing code

✓Full trade audit log stored in Supabase with signal metadata

✓Positions synced with Signa edge recommendations (HOLD/ADD, SELL)

✓Webhook-triggered execution — signal fires, order placed automatically
