Cortex

Overview

Cortex is a Model Context Protocol server that powers a shared knowledge base where people and AI agents collaborate. It lets you and your AI assistants read and write pages, manage atoms, and perform hybrid search across stored information. Because it implements MCP, Claude, Cursor, and other AI tools can call Cortex as native capabilities instead of requiring manual copy-paste workflows.

Cortex runs as a remote hosted service. Connect your MCP client to https://{instance}.cortex.page/api/mcp using an API Key — there's nothing to install locally. The latest release is v1.0.0, available from https://cortex.page.

Cortex appears in the AI & Agents category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain Cortex, claim this listing to verify ownership and keep the information up to date.
