What is the key difference between Arc and Doriku?

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

How do I install Arc or Doriku 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 Arc and Doriku free or paid?

Arc operates under a Free / Open Source model (No auth required). Doriku operates under a Free / Open Source model (No auth required).

Which MCP server has more tools and community activity?

Arc lists 0 tools with 0 views and 0 GitHub stars. Doriku lists 0 tools with 0 views and 0 GitHub stars.

Can I use both Arc and Doriku 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 Arc or Doriku 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 Arc and Doriku free to use, or do they require API keys?

Arc is listed under a Free / Open Source model with No auth required . Doriku 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 Arc and Doriku at the same time in my AI client?

Yes! MCP clients support multi-server orchestration. You can include both arc and doriku-2 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.
