What is MCP Lens?

MCP Lens is an intelligent Model Context Protocol proxy server that solves a core problem faced by AI assistants when using a large number of MCP tools: each tool occupies valuable context window space. With MCP Lens, your AI assistant only needs to see a single tool called 'query'. Then, MCP Lens will intelligently understand your natural language request, automatically select, and invoke the most suitable upstream MCP tool to complete the task.

How to use MCP Lens?

Using MCP Lens is very simple: first, install or build it through the command line. Then, select a preset configuration (such as GitHub, database, search, etc.), set the necessary environment variables, and finally run the proxy server. Your AI assistant can then access all integrated MCP functions through a single 'query' tool.

Use cases

MCP Lens is particularly suitable for complex workflows that require the simultaneous use of multiple MCP tools, such as: developers need to access GitHub, databases, and search tools simultaneously; operations personnel need to monitor AWS, Kubernetes, and Sentry; or any scenario where you want to reduce the context burden on the AI assistant and improve tool - usage efficiency.

Main features

Single query interface
Integrate all MCP tools into a single 'query' tool. The AI assistant only needs to learn one tool interface.
Intelligent routing
Based on OpenRouter's intelligent routing system, it automatically understands the user's intention and selects the most suitable tool.
Preset configurations
Provide a variety of preset configurations, covering reference tools, databases, search, productivity, and development tools, etc.
Context optimization
Significantly reduce the context window occupation and avoid consuming a large number of tokens in the 50 + tool mode.
Easy installation
Support multiple installation methods, including Go installation, source code building, and an interactive configuration wizard.
Advantages
Save a large amount of context window space and improve the efficiency of the AI assistant
Simplify the tool learning curve of the AI assistant. It only needs to master one query interface
The intelligent routing system automatically selects the best tool, reducing manual configuration
Rich preset configurations, ready to use out of the box
Support multiple MCP servers, with strong scalability
Limitations
Require an OpenRouter API key for intelligent routing
Some complex queries may require additional configuration optimization
Integrating new tools requires updating the routing logic
Depend on the stability and availability of upstream MCP servers
