HTTP Transport Mode

For production deployments, you can run the server in HTTP mode:

# Start with HTTP transport
MCP_TRANSPORT_MODE=http MCP_HTTP_PORT=8080 npm run mcp

# The server exposes:
# - /mcp    - MCP protocol endpoint
# - /health - Health check endpoint
# - /metrics - Performance metrics
# - /       - Server info

Testing

# Test MCP server with inspector
mcp-inspector

# Test fediverse interactions
npm run test

# Manual testing with specific actors
# Use the discover-actor tool to test WebFinger discovery

Cross-Platform Compatibility
