CodeHealth MCP

Codebase health analysis that works everywhere. Dead code, circular dependencies, coupling issues, and architectural drift — exposed as MCP tools for Claude Desktop, Cursor, Windsurf, and Slack.

The Problem

Dead code, circular dependencies, excessive coupling, and architectural drift are invisible in day-to-day work. Static analysis tools produce noise in CI dashboards nobody checks. CodeHealth MCP brings these insights into the tools developers actually use — via the Model Context Protocol.

What CodeHealth MCP Does

6 analysis tools, available in any MCP-compatible client:

| Tool | What It Finds | |------|--------------| | analyze_dead_code | Unused functions, classes, modules with file:line + fix suggestions | | detect_circular_deps | Module import cycles via DFS with impact assessment | | analyze_coupling | Fan-out per module, tight cluster detection, refactoring suggestions | | detect_architectural_drift | Layer boundary violations (UI→Data, Business→UI, etc.) | | full_health_scan | All four analyses + 0–100 health score + prioritized action items | | explain_finding | AI-powered detailed explanation of any finding |

Where It Works

| Client | How to Add | |--------|-----------| | Claude Desktop | Add to claude_desktop_config.json | | Cursor / Windsurf | Add to MCP settings | | Slack | Built-in Agent Builder integration with Block Kit UI | | Any MCP client | Standard MCP server (stdio) |

Claude Desktop Config

{
  "mcpServers": {
    "codehealth": {
      "command": "node",
      "args": ["/path/to/codehealth-mcp/mcp-server/index.js"]
    }
  }
}

Quick Start

git clone https://github.com/icohangar-ops/codehealth-mcp.git
cd codehealth-mcp
npm install
cp .env.sample .env
# Edit .env with your LLM API key
npm start

Use in Claude Desktop

Run a full health scan on /path/to/my/repo

Find circular dependencies in the frontend

Check coupling metrics in src/services

Use in Slack

Add the Slack app manifest, enable Agent Builder, and @CodeHealth in any channel.

Slack Integration

CodeHealth MCP ships with a full Slack Agent Builder app featuring:

• Block Kit UI — Severity-coded findings, health scores, actionable suggestions
• Thread-based conversations — Follow-up analysis in threads
• Suggested prompts — One-click analysis triggers
• MCP server — Same tools, available everywhere

Adding Custom Analyzers

Each analyzer follows a simple interface:

function analyze(repoInfo) {
  return {
    type: "your_analysis_type",
    findings: [
      {
        type: "finding_type",
        severity: "critical" | "warning" | "info",
        file: "path/to/file.ts",
        line: 42,
        name: "symbol_name",
        reason: "Why this is a problem",
        suggestion: "How to fix it",
      },
    ],
    stats: { /* summary metrics */ },
  };
}

Add a new analyzer in lib/analyzers/, register it in analysis-engine.js, and it's automatically available in Slack and via MCP.

Roadmap

• [ ] Real AST analysis — ts-morph for TypeScript, tree-sitter for multi-language
• [ ] GitHub App — Automatic analysis on PRs with inline comments
• [ ] Historical trends — Track health score over time per repo
• [ ] Custom architecture rules — Define layer boundaries via config
• [ ] Team dashboards — Aggregate health in Slack Canvas
