The short version

What is enola — the MCP server that catches architecture regressions?

Enola is a tool that maps a codebase to create a deterministic structural baseline, compares it against the state after a change, and reports structural regressions such as dependency cycles, layer violations, and boundary breaches. It operates locally without uploading code or models.

What makes it different

Enola performs architectural regression testing by comparing two deterministic structural maps—before and after a change—to isolate and report only the structural relationships introduced or resolved by that specific change.

Strengths & considerations

Strengths

  • Runs locally with no data uploaded
  • Deterministic structural mapping
  • Integrates with CI and AI agents
  • Open source (Apache 2.0)

Things to consider

  • Requires Git, Go 1.25+, and a C compiler for source builds
  • Windows requires Git Bash, WSL, or manual archive extraction
  • Default policy enforces nothing; requires configuration to fail builds
  • Results are bounded by extractor coverage
