A2A Server Configuration

Provides complete patterns and templates for configuring Agent-to-Agent (A2A) servers with different transport mechanisms (HTTP, STDIO, SSE, WebSocket) following MCP (Model Context Protocol) standards.

Security: API Key Handling

CRITICAL: When generating any configuration files or code:

• NEVER hardcode actual API keys or secrets

• NEVER include real credentials in examples

• NEVER commit sensitive values to git

• ALWAYS use placeholders: your_service_key_here

• ALWAYS create .env.example with placeholders only

• ALWAYS add .env* to .gitignore (except .env.example)

• ALWAYS read from environment variables in code

• ALWAYS document where to obtain keys

Placeholder format: {service}_{env}_your_key_here
