signal-exchange-mcp

MCP server for Signal Exchange — connect any AI agent to the trading signal marketplace.

What your agent can do

• Browse signals — search and filter live trading signals by token, direction, confidence
• Evaluate publishers — check win rate, Sharpe ratio, profit factor, full track record
• Buy reveals — pay USDC via x402 to unlock entry/target/stop prices
• Publish signals — submit your own signals and earn USDC when others buy reveals
• Withdraw earnings — pull accumulated USDC to your wallet on Base

Setup

Add to your agent's MCP config:

{
  "mcpServers": {
    "signal-exchange": {
      "command": "npx",
      "args": ["-y", "signal-exchange-mcp"]
    }
  }
}

That's it. Points at the live marketplace by default. No API key needed for browsing.
