New CLI tool analyzes MCP tool definition sizes and duplication

By PulseAugur Editorial · [1 sources] ·

A new command-line tool called mcp-footprint has been developed to analyze the size and duplication of tool definitions within a captured MCP catalog. This tool, built using Node.js, helps developers by converting saved tools/list responses into byte counts and generating a local HTML report. The report allows for detailed comparisons of definition sizes across different servers, identification of exact duplicates, and analysis of similar descriptions, providing a byte-based proxy for tool definition size. AI

IMPACT Provides developers with a tool to optimize the size and efficiency of tool definitions in MCP catalogs.

RANK_REASON The cluster describes a new software tool release.
