Mercury Agent

Mercury Agent: This AI agent executes tasks across multiple platforms using permission-hardened tools, parallel orchestration, and a local persistent memory system.

Mercury Agent operates as an AI assistant that manages tasks through a multi-agent system, supporting parallel execution with file locks and resource awareness. It includes a "Second Brain" memory system that synthesizes patterns and resolves conflicts to maintain context across sessions. The software runs via a CLI or dashboard and integrates with messaging platforms like Telegram, Discord, Slack, and Signal for interaction. Users maintain control through permission modes, including a whitelist-based approach for commands. It features 40+ built-in tools for tasks such as filesystem management, git operations, and Spotify control. The agent provides verified outcomes rather than simple claims, using an "Autopilot" loop detection system to stop ineffective tasks.
