Full Go port of local-mcp with all core features. Copied from local-mcp-go worktree to consolidate into single-branch repo (easier maintenance). Architecture: - internal/config: Environment variable configuration - internal/models: Shared types (Instruction, Settings, AgentActivity, etc.) - internal/db: SQLite init with modernc.org/sqlite (pure Go, no CGo) - internal/store: Database operations + WakeupSignal + AgentTracker - internal/events: SSE broker for browser /api/events endpoint - internal/mcp: get_user_request MCP tool with 5s keepalive progress bars - internal/api: chi HTTP router with Bearer auth middleware - main.go: Entry point with auto port switching and Windows interactive banner Dependencies: - github.com/mark3labs/mcp-go@v0.46.0 - github.com/go-chi/chi/v5@v5.2.5 - modernc.org/sqlite@v1.47.0 (pure Go SQLite) - github.com/google/uuid@v1.6.0 Static assets embedded via //go:embed static Features matching Python: - Same wait strategy: 50s with 5s progress keepalives - Same hardcoded constants (DEFAULT_WAIT_SECONDS, DEFAULT_EMPTY_RESPONSE) - Auto port switching (tries 8000-8009) - Windows interactive mode (formatted banner on double-click launch) Build: cd go-server && go build -o local-mcp.exe . Run: ./local-mcp.exe Binary size: ~18 MB (vs Python ~60+ MB memory footprint) Startup: ~10 ms (vs Python ~1-2s)
