The listing records `claude mcp add cortex-memory -- cortex-mcp-server ~/.cortex/memory.db` as its setup step. Run it, then follow the repository's instructions for the client configuration; the listing names Claude Desktop, Claude Code, ChatGPT as compatible clients.

Is Cortex MCP Server free?

The listed licence is MIT. Check the upstream terms for permitted use and commercial requirements; a public repository does not by itself mean the software is free or open source. Connected APIs and hosted services may have separate charges.

What can Cortex MCP Server do?

Cortex MCP Server documents 30 tools to the agent, including belief_list, belief_observe, contradiction_check. The descriptions above come from project documentation. A live handshake does not test individual tool behavior.
