What problem does it solve?

This Skill prevents large MCP tool schemas from ballooning your LLM prompt context by routing work through a single, token-efficient Python execution bridge instead of repeatedly loading many server tool definitions.

Core Features & Use Cases

  • Constant token overhead: keeps prompt size near-constant (~200 tokens) regardless of how many MCP servers you connect.
  • Discovery-first MCP proxying: dynamically queries tool schemas and searches docs only when needed, so you don’t pay the context cost upfront.
  • Rootless, sandboxed execution: runs Python in rootless containers with hardened settings (no network, read-only root filesystem) to reduce risk while enabling practical automation.
  • Persistent sessions: maintains variables and MCP client state across calls within the same session for iterative workflows.

Quick Start

Configure Claude Desktop to use a single MCP server called code-execution, then ask it to run a Python snippet that discovers the needed MCP tools and performs the task (for example, fetch data from a configured server, transform it in Python, and write results back).
