Pharos
About Pharos
Pharos functions as a centralized registry for MCP servers, aggregating over 133,000 packages from multiple sources including modelcontextprotocol.io, glama.ai, lobehub.com, mcp.so, mcp.directory, and Smithery. The platform provides a CLI tool that enables users to search, install, and manage MCP servers across different registries using a single command. The CLI verifies server integrity via SHA-512 hashing and writes configuration files for 16 supported MCP clients without manual JSON editing. Pharos supports version control with immutable versions, lockfiles, semantic version resolution, and dependency graphs including circular dependency detection. The system includes an Agent SDK and Pharos-Discovery MCP server that allow AI agents to autonomously discover, install, connect, and update MCP servers while handling OAuth flows inline without browser redirects. The registry also features trending package discovery based on install counts and recency, and provides full attribution to original sources.
