About MCP.Bar

MCP.Bar is the universal package manager and open registry for Model Context Protocol (MCP) servers, enabling seamless discovery and one-command installation.

What is MCP.Bar?

MCP.Bar combines a powerful web platform with a CLI package manager for Model Context Protocol (MCP) servers. Our ecosystem consists of:

  • Open Registry - A curated collection of 1500+ ready-to-use MCP servers
  • Package Manager - The mcpbar CLI tool for one-command installation and management
  • Standardized Manifests - A unified approach to MCP server metadata using mcp.json
  • Developer Resources - Tools and documentation to help you create and share your own MCP servers

Our mission is to simplify the discovery, installation, and management of MCP servers while fostering a vibrant community of AI developers.

How did MCP.Bar get started?

The project emerged from a clear need in the AI development ecosystem. As Model Context Protocol gained adoption, we recognized the challenges in discovering and managing MCP servers across different environments.

What began as a proposal for a standardized manifest format (mcp.json) quickly evolved into a full-fledged package manager and open registry. The goal was to create for MCP servers what npm did for JavaScript packages — a unified ecosystem that balances decentralization with standardization.

How to Contribute

We welcome contributions from the community in several ways:
