TablaCognita

TablaCognita is an MCP (Model Context Protocol) server providing real-time collaborative markdown editing, where browser-based documents can be co-written with any MCP-compatible AI assistant (e.g., Claude, Cursor, Windsurf). It exposes 17 tools for AI reading, writing, document structure access, section manipulation, collaborative locking, revision management, and coordination—all while ensuring all data stays local to the user's browser (no document or content ever leaves local storage). The server acts as a stateless relay for tool calls and results, integrating directly with the MCP ecosystem and supporting web, stdio, and HTTP transports. Ideal for developers, writers, researchers, and teams wanting privacy-first collaborative editing with AI in real time, integrated into any MCP-compatible workflow.
