Hycli

Hycli: CLI tool and MCP server that turns websites into typed AI agent actions using a local browser session.

Hycli is a native desktop application and CLI tool that converts any website into a typed CLI and Model Context Protocol (MCP) server for AI agents. Three AI workers inspect website documentation, frontend bundles, and live network traffic to build structured read and write toolsets. Users can import their real browser login into a local vault protected by the operating system keyring, preventing cookies or tokens from entering LLM prompts. The software runs locally via a single native binary without requiring Rust or Node.js. It features strict origin binding, a local dashboard, and a transport strategy circuit breaker to handle bot challenges and authentication limits safely.
