@meeseeks-sdk/mcp
MCP server for Claude Code — makes the AI verify its own code before giving it to you.
What it does
Instead of Claude Code giving you the first code it generates, this MCP runs a quality gate:
Claude Code calls quality_gate tool
↓
LLM generates code
↓
Sandbox executes it (real Node.js subprocess)
↓
Score 0-10 based on correctness + efficiency
↓
Score ≥ 8? → return verified code
Score < 8? → feed failures back to LLM → retry
You get code that already survived real execution — not just what looked good at first glance.
Install
npm install -g @meeseeks-sdk/mcp
Setup with Claude Code
claude mcp add meeseeks --scope user npx @meeseeks-sdk/mcp
That's it. The quality_gate tool is now available in all your Claude Code sessions.
Tell Claude when to use it
Add to your project's CLAUDE.md or ~/.claude/CLAUDE.md:
## Code Generation
When writing isolated utility functions or algorithms (any language),
use the meeseeks__quality_gate tool instead of writing directly.
Use mode: "fast" if the pattern was used before, "balanced" for new tasks.
For Dart/Flutter/Python code: always pass harness: "free".
For JS/Node.js utilities: omit harness (auto-detected).
Tool: quality_gate
| Parameter | Type | Default | Description |
|---|---|---|---|
task | string | required | What to build — be specific about function signature and export format |
mode | fast|balanced|quality | fast | fast=1 iter, balanced=3, quality=5 |
harness | string | auto-detected | js-api, js-lrucache, js-ratelimiter, js-circuitbreaker, js-promisepool, js-maze, js-sudoku, js-wordle, free |
projectContext | string | — | Stack description for the judge: "TypeScript + Express + PostgreSQL" |
minScore | number | 8 | Stop when score ≥ this value |
Requirements
- Node.js 18+
- AWS credentials configured (
~/.aws/credentials) for Bedrock adapter - Or set
AWS_REGIONenvironment variable
Knowledge inheritance
The MCP stores winning strategies in ~/.meeseeks/memory.db (SQLite). Next time you ask for a similar function, the proven approach is injected into the prompt — better first attempts over time.
