Sombra

Sombra is an MCP (Model Context Protocol) server that enables AI agents to save, search, organize, and distill web research and content. It is ideal for users who want to connect their AI agents (like Claude.ai, Claude Code, or ChatGPT) to manage and store collected web resources, research, and notes in a structured, retrievable manner. Sombra is especially useful for those who need to organize and revisit web research across platforms and tools, with support for OAuth 2.1 authentication and browser-based capture extensions.
