Cuts the cost of MCP tokens by 75–98%. Code SDK builder for Claude + presets + skill harvester. Everything is in Russian 🥗
Overview
A set of skills for Claude that converts any MCP server into a "code SDK": instead of loading the schemas of all tools into the model context for each request, Claude writes regular code that calls the same tools. The pattern is described in the Anthropic engineering blog "Code execution with MCP" (in their example, the savings are from 150,000 tokens to 2,000, i.e. 98.7%). (Requires Code Execution enabled.) With a direct MCP connection, most clients put the toolbox schemas in context on the request. 40 tools ≈ tens of thousands of tokens, even if you asked "hello". Plus, each intermediate result (for example, a hefty JSON from Mixpanel) is pumped through the model twice: at the output of one tool and at the input of the next. With the code SDK: 1. The model reads only INDEX.md — one line per tool. 2. The full schema opens only for the tool that is actually needed. 3. The data between calls lives in python script variables, not in the context. 4.

Works in Claude Code and Cowork/claude.ai (requires feature enabled code execution).
