Which integrations are available for this server?

Provides platform-specific code review rules focusing on Manifest configuration, permissions, ProGuard, lifecycle violations, and context leaks. Provides platform-specific code review rules focusing on async misuse, setState patterns, dispose() methods, BuildContext in async operations, and Riverpod memory leaks. Reads uncommitted git diffs to provide code review analysis and severity scoring (P0/P1/P2) across multiple AI agents. Provides platform-specific code review rules focusing on plist configuration, ATS, keychain, signing, main thread UI violations, and retain cycles. Uses the OpenAI API through the Codex CLI to provide AI-powered code review and participate in multi-agent debates for code analysis and planning.

How do I use Debate Agent MCP?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Debate Agent MCP review the latest commit for security issues" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Debate Agent MCP

EXPERIMENTAL: This project is in active development. APIs and features may change without notice. Use at your own risk in production environments.

How It Works

No Authentication Required

The MCP itself requires no API keys or authentication. It orchestrates your locally installed CLI tools:

┌─────────────────────────────────────────────────────────────────┐
│  YOUR MACHINE                                                   │
│                                                                 │
│  ~/.claude/credentials  ──► claude CLI ──► Anthropic API       │
│  ~/.codex/credentials   ──► codex CLI  ──► OpenAI API          │
│                                                                 │
│  The MCP just runs: spawn("claude", ["--print", prompt])        │
│  Same as typing in your terminal!                               │
│                                                                 │
└─────────────────────────────────────────────────────────────────┘

Execution Flow

Step 1: Build Prompt
├── Combine review question + git diff + platform rules
├── Add P0/P1/P2 severity definitions
└── Request JSON output format

Step 2: Parallel Execution
├── spawn("/opt/homebrew/bin/claude", ["--print", prompt])
├── spawn("/opt/homebrew/bin/codex", ["exec", prompt])
└── Both run simultaneously via Promise.all()

Step 3: Capture Output
├── Read stdout from each CLI process
└── Parse JSON responses

Step 4: Deterministic Scoring (No AI)
├── Count P0/P1/P2 findings
├── Check file accuracy against diff
├── Penalize false positives
└── Score clarity and fix quality

Step 5: Merge & Report
├── Pick winner by highest score
├── Combine unique findings from all agents
└── Generate final recommendation

360 Debate Feature (v2.0)

The 360 Debate feature provides multi-turn cross-review with confidence scoring. It supports two modes:

Mode	Description	Output
review	P0/P1/P2 code review findings	`.debate/review-TIMESTAMP.md`
plan	Implementation planning with consensus	`.debate/plan-TIMESTAMP.md`

360 Debate Pipeline

Round 1: Initial Review (Parallel)
┌─────────┐     ┌─────────┐
│ Claude  │     │ Codex   │
│ Review  │     │ Review  │
└────┬────┘     └────┬────┘
     │               │
     ▼               ▼
Round 2: 360 Cross-Review (Each agent reviews ALL others)
┌─────────────────────────────────────────┐
│ Claude reviews Codex's findings         │
│ Codex reviews Claude's findings         │
│ "Is P0 about null pointer valid?"       │

Final Report: .debate/review-*.md or .debate/plan-*.md

Review Mode Example

// Run 360 code review
const result = await runDebate360({
  question: 'Review this code for security issues',
  mode: 'review',  // P0/P1/P2 severity scoring
  agents: ['claude', 'codex'],
  platform: 'backend',
  maxRounds: 3,
  confidenceThreshold: 80,
});

// Output: .debate/review-2025-01-20T10-30-00.md
console.log(result.finalFindings);  // Validated P0/P1/P2 findings

Plan Mode Example

// Run 360 implementation planning
const result = await runDebate360({
  question: 'Plan how to add user authentication',
  mode: 'plan',  // Consensus-based, no severity
  agents: ['claude', 'codex'],
  maxRounds: 3,
  confidenceThreshold: 80,
});

// Output: .debate/plan-2025-01-20T10-30-00.md
console.log(result.finalPlan);  // Validated implementation steps

Mode Comparison

Aspect	Review Mode	Plan Mode
Purpose	Find bugs, security issues	Plan implementation approach
Scoring	P0/P1/P2 severity (max 134 pts)	Clarity + Consensus (0-100)
Output	Findings with fix suggestions	Implementation steps with phases
Winner	Highest severity score	Highest consensus + clarity
Final Result	Merged P0/P1/P2 findings	Merged implementation plan
MD File	`review-TIMESTAMP.md`	`plan-TIMESTAMP.md`

Benefits of 360 Debate:

Eliminate hallucinated findings (validated by multiple agents)
Catch missed issues (one agent finds what another missed)
Build confidence scores (80% threshold ensures agreement)
Reduce false positives (adversarial review catches incorrect assessments)
Comprehensive report in .debate/ directory

Severity Levels

Level	Criteria
P0	Breaking defects, crashes, data loss, security/privacy problems, build blockers
P1	Likely bugs/regressions, incorrect logic, missing error-handling, missing tests
P2	Minor correctness issues, small logic gaps, non-blocking test gaps

Defined in: packages/core/src/prompts/review-template.ts

Platform-Specific Rules

Platform	Focus Areas
flutter	Async misuse, setState, dispose(), BuildContext in async, Riverpod leaks
android	Manifest, permissions, ProGuard, lifecycle violations, context leaks
ios	plist, ATS, keychain, signing, main thread UI, retain cycles
backend	DTO mismatch, HTTP codes, SQL injection, auth flaws, rate limiting
general	Null pointers, resource leaks, race conditions, XSS, input validation

Defined in: packages/core/src/prompts/platform-rules.ts

Scoring System

The scoring is deterministic (no AI) - pure rule-based evaluation:

Criteria	Points	Max
P0 Finding	+15	45
P1 Finding	+8	32
P2 Finding	+3	12
False Positive	-10	-30
Concrete Fix	+5	25
File Accuracy	+2	10
Clarity	0-10	10

Maximum possible score: 134 Minimum possible score: -30
