# 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
