Zero-configuration AI context generation system that analyzes any codebase instantly through CLI, MCP, or HTTP interfaces. Built by Pragmatic AI Labs with extreme quality standards and zero tolerance for technical debt.
Toyota Way Success: Achieved 97% complexity reduction in stubs.rs through complete modular refactoring (v0.29.5). Project maintains zero tolerance standards: 0 SATD comments, 0 failing doctests, 0 failing property tests, 72+ comprehensive property tests, and proper separation of concerns across all components. Latest refactoring created dedicated modules (language_analyzer.rs, defect_formatter.rs, dead_code_formatter.rs) eliminating 549 lines of duplicated code while maintaining full functionality β

AI agents can now chain analysis tools using the --files parameter:
# Step 1: Find complexity hotspots
pmat analyze complexity --top-files 5 --format json
# Step 2: Deep analyze those specific files (MCP composition)
pmat analyze comprehensive --files src/complex.rs,src/legacy.rs
# Step 3: Target refactoring on problematic files
pmat refactor auto --files src/complex.rsMCP Agent Workflow Example:
// AI agent discovers hotspots
const hotspots = await callTool("pmat_analyze_complexity", {
top_files: 5,
format: "json"
});
// Agent extracts file paths and performs deep analysis
const detailed = await callTool("pmat_analyze_comprehensive", {
files: hotspots.files.map(f => f.path)
});
// Agent generates targeted refactoring plan
const refactor = await callTool("pmat_refactor_auto", {
files: detailed.high_risk_files
});# Start server
