tomevault-io Swift Complexity Analysis
Use the analyze_complexity and analyze_code_string MCP tools from the swift-complexity server to analyze Swift code.
When to use each tool
analyze_complexity: When analyzing files or directories on disk. Supports recursive analysis, threshold filtering, and LCOM4 cohesion metrics.analyze_code_string: When analyzing a Swift code snippet directly without needing a file on disk.
Workflow
- Use
analyze_complexitywith"format": "json"for structured results - Identify functions with high complexity (cyclomatic >= 10 or cognitive >= 15 are common thresholds)
- Provide actionable recommendations to reduce complexity (extract methods, simplify conditionals, use guard clauses)
Interpreting results
- Cyclomatic complexity: Number of independent paths through code. Higher = more test cases needed.
- Cognitive complexity: How hard the code is to understand. Accounts for nesting depth.
- LCOM4: Class cohesion metric. 1 = cohesive, higher = consider splitting the class.
Example usage
Analyze a directory recursively with a threshold:
{
"paths": ["Sources/"],
"recursive": true,
"threshold": 10,
"format": "json"
}
