AI Agent
Open Source
Mercury is an open-source AI agent (MIT) that thinks, acts, and asks permission. It features multi-agent orchestration with parallel sub-agents, intelligent loop detection via Autopilot, 40+ built-in tools (filesystem, shell, git, GitHub, Spotify), a Second Brain memory system, and runs 24/7 headless from your terminal or Telegram with full permission controls.
Multi-agent orchestration with parallel sub-agents — file locks prevent conflicts, resource-aware concurrency, non-blocking chat while agents run; Mercury Autopilot detects stuck loops by analyzing parameter diversity (>60%) and success rate (>70%) and halts unproductive paths automatically
40+ built-in tools with zero configuration — filesystem, shell, git, GitHub PRs/issues, Spotify (14 tools + DJ mode), Markdown skill system with scheduling; real-time progress via single live-edited status card on CLI and Telegram with token stats and budget tracking
Second Brain memory with conscious/subconscious layers — active working memory + persistent long-term recall in local SQLite; person tracking with alias resolution and graph visualization; three interfaces: CLI (TUI), Web Dashboard (React SPA at localhost:6174), and Telegram with inline keyboard permissions
