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: Evaluate commands

# Allowed — exit 0
npx a2a-trustgate eval "echo hello"

# Blocked — exit 1
npx a2a-trustgate eval "rm -rf /"

# Verify your connection
a2a verify
