- Native MCP bridge using Anthropic’s official protocol
- Async task execution with progress checking and results
- Git branch isolation per task; main branch stays untouched
- Bidirectional bridge: Claude Chat → Claude Code and Claude Code → Herald
- Multi-project support with per-project tool restrictions
- SQLite persistence for task history across restarts
- Single ~15MB Go binary, zero CGO, only 6 dependencies

Install the single Go binary via the install script or build from source (Go 1.26+). Configure a YAML file with your server domain, projects, and optional ngrok tunnel. Run herald serve to start the server, then add a Custom Connector in Claude Chat pointing to https://your-domain.com/mcp and authenticate via OAuth. Claude Chat automatically discovers 10 MCP tools for controlling your workstation.
