Welcome to Lunar.dev MCPX

Lunar.dev MCPX is a lightweight, unified MCP gateway for orchestrating and securing AI agents and applications across multiple MCP servers. Designed for teams managing multiple servers and tools, MCPX provides a single point of control with full visibility into all traffic and enforceable policies on how tools are accessed, configured, and used.

Why MCPX

Agents and AI-powered applications are expanding their capabilities by connecting to MCP servers, and the number of tool servers they rely on is only increasing. MCPX helps you stay in control with:

• Centralized access. Aggregate and expose any number of local and remote MCP servers through a single endpoint.
• Policy enforcement. Control which tools and methods are accessible to which agents.
• Customization. Tailor tools to your specific workflows.
• Full observability. Track usage, latency, and errors across all tool calls.
• Authorization management. Manage all your secrets, API keys, and OAuth tokens in one place.

With MCPX, you can safely connect your agents to anything without losing control.
