Best For

Contract is available with explicit auth and schema references.

Not Ideal For

firebat is not ideal for teams that need stronger public trust telemetry, lower setup complexity, or more explicit contract coverage before production rollout.

Setup snapshot

git clone https://github.com/parkrevil/firebat.git
  1. 1

    Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

## firebat (MCP Code Quality Scanner)

This project uses a firebat MCP server for automated code quality analysis.

### Tools
- 🔍 Analysis: `scan`

### Required Rules
- After any code change, always run `scan` to check for quality regressions.
- Review scan findings and address them in priority order before moving on.

### When to Use What
- After editing code → `scan`

CLI Reference

firebat scan [targets...] [options]

Commands

| Command | Description | |---------|-------------| | scan | Run code analysis (default command) | | install | Set up firebat config files in this project | | update | Sync config files with latest templates | | cache clean | Delete cached analysis data (.firebat/*.sqlite) | | mcp | Start MCP server (stdio transport) |

Scan Options

| Flag | Default | Description | |------|---------|-------------| | --format text\|json | text | Output format | | --min-size <n\|auto> | auto | Min AST node size for duplicate detection | | --max-forward-depth <n> | 0 | Max thin-wrapper chain depth | | --only <list> | all | Comma-separated detectors to run | | --fix | off | Apply safe autofixes (oxfmt --write; oxlint --fix) | | --config <path> | .firebatrc.jsonc | Config file path | | --no-exit | off | Always exit 0, even with findings | | --log-level <level> | info | error | warn | info | debug | trace | | --log-stack | off | Include stack traces in log output |

Detectors (15)

All detectors run by default. Use --only to select a subset.

Code Quality

| Detector | What it finds | |----------|---------------| | exact-duplicates | Identical AST subtrees across files | | structural-duplicates | Structurally similar code (clone classes) | | waste | Dead stores — variables assigned but never read, or overwritten before read | | nesting | Deep nesting that harms readability, with refactoring suggestions | | early-return | Functions that would benefit from guard clauses / early returns | | noop | No-op code: side-effect-free expression statements, constant conditions, empty catch blocks, self-assignments, empty function bodies | | forwarding | Thin wrappers that only forward calls, and long forwarding chains |

Architecture

| Detector | What it finds | |----------|---------------| | barrel-policy | Barrel file violations: export *, deep imports, missing/invalid index files | | unknown-proof | Unsafe unknown/any usage: type assertions, unvalidated unknown, inferred any | | api-drift | Functions with the same name but inconsistent signatures across files | | dependencies | Import dependency cycles and edge-cut hints | | coupling | High-coupling hotspot modules |

External Tools

| Detector | Tool | What it finds | |----------|------|---------------| | lint | oxlint | Lint errors and warnings | | format | oxfmt | Files that need formatting | | typecheck | tsgo | Type errors and warnings with code frames |

MCP Integration

firebat exposes a single tool (scan) via the Model Context Protocol for AI agent integration.

Setup

Add to your MCP client config (e.g. Claude Desktop, VS Code):

{
  "mcpServers": {
    "firebat": {
      "command": "node",
      "args": ["path/to/dist/firebat.js", "mcp"]
    }
  }
}

Agent Prompt (Recommended)

Copy the following block into your agent's instruction file (e.g. copilot-instructions.md, AGENTS.md, .cursor/rules) so your AI agent can discover and leverage all firebat tools automatically:

## firebat (MCP Code Quality Scanner)

This project uses a firebat MCP server for automated code quality analysis.

### Tools
- 🔍 Analysis: `scan`

### Required Rules
- After any code change, always run `scan` to check for quality regressions.
- Review scan findings and address them in priority order before moving on.

### When to Use What
- After editing code → `scan`

Tip: firebat install prints this block automatically so you can copy it right away.

Configuration

Create .firebatrc.jsonc in your project root:

{
  // Detectors to run (default: all)
  "detectors": ["waste", "noop", "nesting"],

  // Per-feature configuration
  "features": {
    "unknown-proof": {
      "boundaryGlobs": ["src/adapters/**"]
    },
    "barrel-policy": {
      "ignoreGlobs": ["dist/**"]
    }
  }
}

Architecture

src/
  adapters/       Entrypoints & composition root (CLI, MCP)
  application/    Use-case orchestration (no direct I/O imports)
  ports/          Interfaces for external I/O
  infrastructure/ I/O implementations (SQLite, tsgo, oxlint, ast-grep)
  engine/         Pure computation (AST parsing, CFG, hashing, detection)
  features/       Pure analysis logic per detector

Dependency rules:

  • application/ → depends on ports/ only (never infrastructure/)
  • infrastructure/ → implements ports/
  • adapters/ → assembles everything (composition root)
  • engine/ + features/ → pure, no I/O dependencies

Development

bun test                # Run all tests
bun run build           # Build to dist/
bun run deps            # Check dependency rules
bun run knip            # Find unused exports
