Step 1: Set up A2A TrustGate

Run the quickstart wizard — prints API key setup, MCP config, CLAUDE.md snippet, and wrapper generators:

npx a2a-trustgate quickstart

# Then run the interactive setup:
npx a2a-trustgate setup

Step 2: Configure MCP

npx a2a-trustgate configure mcp

# Adds to .mcp.json:
{
  "mcpServers": {
    "a2a-trustgate": {
      "command": "npx",
      "args": ["a2a-trustgate", "server"]
    }
  }
}
