micro/mu provides agents with *67* real internet tools via a single MCP endpoint, replacing fragmented API wrappers. It includes email (SMTP/DKIM), web search, markets, weather, and more, all running in one Go binary. Users self-host or use micro.mu, with tools like mail_inbox reading real inboxes and db_create writing to actual storage. The system uses MCP authorizations—no API keys—to integrate with agents like Claude Desktop. Tools cost credits from the user’s balance, visible at micro.mu/tools.

The platform emphasizes ownership: tools are server-side Go services, not third-party integrations. Extending micro/mu means adding a service once, automatically enabling it for agents, CLI, and apps. Identity is server-side, preventing data forgery. The built-in agent uses LLMs (Claude, Atlas Cloud) to compose answers across sessions. Self-hosting lets operators monetize tool usage.

CLI access mirrors server tools. Commands like mu weather_forecast or mu agent interact directly. Configuration via JSON files (feeds, prompts) and environment variables allows customization. Setup includes signing in via browser or PATs, with admin controls for fees and integrations. Prebuilt templates for Discord/Telegram bots simplify outreach.

Licensed under AGPL-3.0, micro/mu is open-source. Self-hosted instances retain full control, while the hosted version offers convenience. Documentation covers MCP details, architecture, and tool catalogs. The project prioritizes real capabilities over API layers, aiming to reduce setup complexity for agents.
