A panel of 45 specialized judges that evaluate code across security, cost, compliance, accessibility, and architectural dimensions. Built for AI-generated code review, it combines deterministic AST analysis with LLM-powered deep reviews, exposing tools like evaluateCode, applyFixes, and generateReport through the MCP interface. Ships with 200+ auto-fix patches, SARIF output for GitHub Code Scanning, and agentic skills like ai-code-review and release-gate. The CLI companion lets you run judges eval from CI or terminal, while the MCP server brings the full tribunal into Claude, Cursor, or any MCP client. Includes diff-only evaluation for PRs, license scanning for supply chain compliance, and baseline suppression for known findings.
An MCP (Model Context Protocol) server that provides a panel of 45 specialized judges to evaluate AI-generated code — acting as an independent quality gate regardless of which project is being reviewed. Combines deterministic pattern matching & AST analysis (instant, offline, zero LLM calls) with LLM-powered deep-review prompts that let your AI assistant perform expert-persona analysis across all 45 domains.

The MCP server runs on stdio and is started by your MCP client (VS Code, Claude Desktop, etc.).
Configure it in your MCP settings (e.g. mcp.json):
{
"servers": {
"judges": {
"type": "stdio",
"command": "npx",
"args": ["-y", "@kevinrabun/judges"]
}
}
}
Or run the server directly:
npx @kevinrabun/judges
# Starts the MCP server on stdio

.judgesrc.json(supports${ENV_VAR}substitution viaexpandEnvPlaceholders). See Configuration.
AI code generators (Copilot, Cursor, Claude, ChatGPT, etc.) write code fast — but they routinely produce insecure defaults, missing auth, hardcoded secrets, and poor error handling. Human reviewers catch some of this, but nobody reviews 45 dimensions consistently.

Judges doesn't replace linters — it covers the dimensions linters don't: authentication strategy, data sovereignty, cost patterns, accessibility, framework-specific anti-patterns, and architectural issues across multiple files.

This evaluates examples/sample-vulnerable-api.ts — a file intentionally packed with security holes, performance anti-patterns, and code quality issues — and prints a full verdict with per-judge scores and findings.
The demo now also includes an App Builder Workflow (3-step) section. In a single run, you get both tribunal output and workflow output:

Install the Judges Panel extension from the Marketplace. It provides:
@judges chat participant — type @judges in Copilot Chat, or just ask for a "judges panel review" and Copilot routes automaticallycode --install-extension kevinrabun.judges-panel
If you prefer explicit workspace config (or want teammates without the extension to benefit), create .vscode/mcp.json:
{
"servers": {
"judges": {
"command": "npx",
"args": ["-y", "@kevinrabun/judges"]
}
}
}
Add to claude_desktop_config.json:
{
"mcpServers": {
"judges": {
"command": "npx",
"args": ["-y", "@kevinrabun/judges"]
}
}
}
Use the same npx command for any MCP-compatible client:
{
"command": "npx",
"args": ["-y", "@kevinrabun/judges"]
}
Yes — users can include Judges as part of GitHub-based review workflows, with one important caveat:
copilot-pull-request-reviewer on GitHub does not currently let you directly attach arbitrary local MCP servers the same way VS Code does.Create .github/workflows/judges-pr-review.yml:

console.log('Overall:', result.overallVerdict, result.averageScore);"
- name: Upload report artifact

This gives every PR a reproducible Judges output your team (and Copilot) can reference.
Add .github/instructions/judges.instructions.md with guidance such as:
When reviewing pull requests:
1. Read the latest Judges report artifact/check output first.
2. Prioritize CRITICAL and HIGH findings in remediation guidance.
3. If findings conflict, defer to security/compliance-related Judges.
4. Include rule IDs (e.g., DATA-001, CYBER-004) in suggested fixes.
This helps keep Copilot feedback aligned with Judges findings.
All commands support --help for usage details.

The tribunal operates in three layers:
Pattern-Based Analysis — All tools (evaluate_code, evaluate_code_single_judge, evaluate_project, evaluate_diff) perform heuristic analysis using regex pattern matching to catch common anti-patterns. This layer is instant, deterministic, and runs entirely offline with zero external API calls.
AST-Based Structural Analysis — The Code Structure judge (STRUCT-* rules) uses real Abstract Syntax Tree parsing to measure cyclomatic complexity, nesting depth, function length, parameter count, dead code, and type safety with precision that regex cannot achieve. All supported languages — TypeScript, JavaScript, Python, Rust, Go, Java, C#, and C++ — are parsed via tree-sitter WASM grammars (real syntax trees compiled to WebAssembly, in-process, zero native dependencies). A scope-tracking structural parser is kept as a fallback when WASM grammars are unavailable. No external AST server required.
LLM-Powered Deep Analysis (Prompts) — The server exposes MCP prompts (e.g., judge-data-security, judge-cybersecurity) that provide each judge's expert persona as a system prompt. When used by an LLM-based client (Copilot, Claude, Cursor, etc.), the host LLM performs deeper, context-aware probabilistic analysis beyond what static patterns can detect. This is where the systemPrompt on each judge comes alive — Judges itself makes no LLM calls, but it provides the expert criteria so your AI assistant can act as 45 specialized reviewers.
Judges Panel is a dual-layer review system: instant deterministic tools (offline, no API keys) for pattern and AST analysis, plus 45 expert-persona MCP prompts that unlock LLM-powered deep analysis when connected to an AI client. It does not try to be a CVE scanner or a linter. Those capabilities belong in dedicated MCP servers that an AI agent can orchestrate alongside Judges.
Unlike earlier versions that recommended a separate AST MCP server, Judges Panel now includes real AST-based structural analysis out of the box:
The Code Structure judge (STRUCT-*) uses these parsers to accurately measure:
| Rule | Metric | Threshold |
|---|---|---|
STRUCT-001 | Cyclomatic complexity | > 10 per function (high) |
STRUCT-002 | Nesting depth | > 4 levels (medium) |
STRUCT-003 | Function length | > 50 lines (medium) |
STRUCT-004 | Parameter count | > 5 parameters (medium) |
STRUCT-005 | Dead code | Unreachable statements (low) |
STRUCT-006 | Weak types | any, dynamic, Object, interface{}, unsafe (medium) |
STRUCT-007 | File complexity | > 40 total cyclomatic complexity (high) |
STRUCT-008 | Extreme complexity | > 20 per function (critical) |
STRUCT-009 | Extreme parameters | > 8 parameters (high) |
STRUCT-010 | Extreme function length | > 150 lines (high) |
When your AI coding assistant connects to multiple MCP servers, each one contributes its specialty:
