Routes multi-tool workflows through MCP servers for large datasets and pipelines. Use when Bash tool overhead is limiting throughput on data-heavy tasks.

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'mcp-code-execution' ] || [ -L ~/.agents/skills/'mcp-code-execution' ]; then echo 'A skill folder named mcp-code-execution already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/athola/claude-night-market' "$d" && git -C "$d" checkout --quiet '4f94139a2d325f14442a62dc0b4cd28b41dbb5ba' -- 'plugins/conserve/skills/mcp-code-execution' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/conserve/skills/mcp-code-execution' ~/.agents/skills/'mcp-code-execution' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'mcp-code-execution' ~/.claude/skills/'mcp-code-execution' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
