mcp-code-execution SKILL.md skillA

mcp-code-execution from athola/claude-night-market is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add athola/claude-night-market/mcp-code-execution@git:20261005.72b0a8f

Pins git:20261005.72b0a8f in mdr.lock. Pin the fingerprint instead.

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

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# MCP Code Execution Hub

## Quick Start

This skill is an orchestration hub, not a CLI. It activates
inside a Claude Code session when one of the trigger keywords
below appears, or when invoked explicitly:

```
Skill(conserve:mcp-code-execution)
```

The hub then routes to the relevant sub-skill modules
(`mcp-subagents`, `mcp-patterns`, `mcp-validation`) based on
the detected workflow shape. There is no separate install
step or CLI entry point.

## When To Use
- **Automatic**: Keywords: `code execution`, `MCP`, `tool chain`, `data pipeline`, `MECW`
- **Tool Chains**: >3 tools chained sequentially
- **Data Processing**: Large datasets (>10k rows) or files (>50KB)
- **Context Pressure**: Current usage >25% of total window (proactive context management)

> **MCP Tool Search (Claude Code 2.1.7+)**: When MCP tool
> descriptions exceed 10% of context, tools are automatically
> deferred and discovered via MCPSearch instead of being loaded
> upfront. This reduces token overhead by ~85% but means tools
> must be discovered on-demand. Haiku models do not support tool
> search. Configure threshold with `ENABLE_TOOL_SEARCH=auto:N`
> where N is the percentage.

How to install

The exact contents, by fingerprint
mdr add athola/claude-night-market/mcp-code-execution@sha256:7c7cbaa24fbd7bed

The line at the top of this page pins the label git:20261005.72b0a8f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
