What is the key difference between Cortex and Lore?

Cortex belongs to the Knowledge & Memory category with cloud HTTP/SSE execution, while Lore belongs to the Knowledge & Memory category with local stdio execution.

How do I install Cortex or Lore in Claude Desktop or Cursor?

Copy the mcpServers JSON configuration snippet provided on this page into your claude_desktop_config.json or ~/.cursor/mcp.json file and restart your AI client.

Are Cortex and Lore free or paid?

Cortex operates under a Free / Open Source model (No auth required). Lore operates under a Free / Open Source model (No auth required).

Which MCP server has more tools and community activity?

Cortex lists 0 tools with 0 views and 0 GitHub stars. Lore lists 0 tools with 0 views and 0 GitHub stars.

Can I use both Cortex and Lore together in the same MCP host?

Yes! MCP hosts like Claude Desktop, Cursor, Windsurf, Cline, and VS Code support configuring multiple servers under the mcpServers object simultaneously.

How do I install Cortex or Lore in Claude Desktop, Cursor, or Windsurf?

Both servers follow the standard Model Context Protocol configuration format. Simply copy the JSON block from the configuration section above and paste it into your AI client's mcpServers configuration object (for instance in claude_desktop_config.json or ~/.cursor/mcp.json ), then completely restart or refresh the application.

Are Cortex and Lore free to use, or do they require API keys?

Cortex is listed under a Free / Open Source model with No auth required . Lore operates under a Free / Open Source model with No auth required . If environment variables are required (such as API keys), be sure to define them under the env key in your MCP client's configuration file.

Can I run both Cortex and Lore at the same time in my AI client?

Yes! MCP clients support multi-server orchestration. You can include both cortex-2 and lore as distinct keys inside the single mcpServers object in your configuration file. Your AI assistant will automatically select and call the appropriate tool from either server during chat sessions.

Which MCP server has higher directory engagement and quality ratings?

On AllMCPs, Cortex has a Quality Score of 45 /100 ( Fair ) with 0 views, 0 installs, and 0 GitHub stars. Lore holds a Quality Score of 27 /100 ( Emerging ) with 0 views, 0 installs, and 0 GitHub stars.
