Static code analyzer with MCP server. Gives AI agents access to complexity metrics, coupling analysis, community detection, risk scoring, and test quality, without reading every file.

Overview

AST Metrics is a multi-language static code analyzer (Go, PHP, Python, Rust, TypeScript...) that exposes architectural insights via MCP. AI coding agents can query complexity hotspots, dependency graphs, coupling metrics, architectural communities, and test quality on demand.

No server required. No account. One binary. Works offline.

Tools exposed

analyze_project -- High-level project overview: languages, average complexity, maintainability, top risks
get_file_metrics -- Detailed metrics for a specific file (complexity, LOC, coupling, maintainability)
find_risky_code -- Ranked list of riskiest files/classes (composite score: complexity + coupling + change frequency)
find_complex_code -- Functions/classes above a cyclomatic complexity threshold
get_dependencies -- Dependency subgraph around a component
get_coupling -- Afferent and efferent coupling for a component
get_communities -- Architectural community detection with modularity metrics
get_test_quality -- Test isolation, traceability, god tests, orphan classes

Installation

curl -s https://raw.githubusercontent.com/Halleck45/ast-metrics/main/scripts/download.sh|bash

Configuration

Add to .mcp.json:

{
  "mcpServers": {
    "ast-metrics": {
      "command": "ast-metrics",
      "args": ["mcp", "."]
    }
  }
}

Try in Playground

Server Config

{
  "mcpServers": {
    "ast-metrics": {
      "command": "ast-metrics",
      "args": [
        "mcp",
        "."
      ]
    }
  }
}
