# astllm-mcp

> Use this tool when you need to efficiently index and retrieve specific code components, such as functions or classes, across multiple programming languages. It solves the problem of excessive token costs by providing O(1) byte-offset access to code symbols, allowing for fast and cost-effective code analysis. The astllm-mcp server takes in code files and outputs specific code components, making it ideal for use cases where detailed code inspection is required without incurring high token costs.
