Grounded Docs MCP Server: Open-Source Alternative to Context7, Nia, and Ref.Tools
Grounded Docs is an MCP server that builds a local, version-aware index of documentation from websites, code repositories, package registries, local files, and archives for AI coding assistants. It helps assistants retrieve current project-specific documentation and supports MCP-compatible clients such as Claude, Cline, and similar tools. The catalogue add-ons provide skills, commands, and instructions for working with this documentation server.
