CodePeel MCP Server

AI code review tools for Claude Code, Cline, Roo, and other MCP-compatible agents.

What it does

When you're vibe coding with an AI agent, CodePeel acts as a second opinion — reviewing the generated code for bugs, security issues, and bad patterns before you commit.

Tools

Setup

1. Get your API token

1. Sign in at codepeel.com

2. Go to Settings → API Tokens

3. Click Create Token and copy the token (starts with cpk_)

API tokens don't expire — they work until you revoke them.

2. Configure MCP

Add to your MCP config (.kiro/settings/mcp.json, claude_desktop_config.json, or Cline settings):

{
  "mcpServers": {
    "codepeel": {
      "command": "npx",
      "args": ["-y", "github:codepeel/mcp-server"],
      "env": {
        "CODEPEEL_TOKEN": "cpk_your_token_here"
      }
    }
  }
}

3. Use it

The AI agent will automatically have access to CodePeel's review tools. You can ask it to:

• "Review my recent changes for bugs"

• "Check this diff for security issues"

• "Fix the null pointer issue in auth.ts"

• "How many reviews do I have left?"

Example Usage

Review code changes

Agent: I'll review your changes using CodePeel.
[calls review_code with git diff output]

CodePeel found 3 issues:
🟠 Potential null pointer in user.ts:45
🟡 Missing error handling in api.ts:23
🔵 Unused import in utils.ts:1

Self-review during vibe coding

The AI can review its own output before presenting it to you:

You: Build a login form with validation
Agent: [writes code, then calls review_code on its own output]
Agent: I found a potential XSS issue in my implementation. Let me fix that...
[calls fix_code, applies the fix]
Agent: Here's the login form — I caught and fixed a security issue during generation.
