MCP Connectors
Connect any AI tool to your knowledge base via MCP. Give Claude, Cursor, or any MCP-compatible agent access to your documents through secure OAuth.
AI Tools Can't Access Your Knowledge
Your AI assistant doesn't know about your company's documents, policies, or data. Every conversation requires manually pasting context. MCP connectors let any AI tool query your knowledge base directly.
