Cube
Ask governed data questions against Cube's semantic layer of metrics. With Lunar.dev MCPX, the MCP Gateway for secure and governed tool access, you connect the Cube MCP server to Claude, ChatGPT, Cursor, and any MCP client through one gateway that routes, authenticates, and governs every Cube tool call against your policies.
Why MCPX
MCPX is Lunar.dev's MCP Gateway. It sits between your AI agents and your MCP servers as a single gateway for every tool call, routing, authenticating, and governing traffic against your policies. Connect Cube once and govern it everywhere: role-based access per agent with on-behalf-of attribution, real-time visibility, and an immutable audit trail of who did what, all deployable inside your own VPC.
