For AI agents

Use CodeBust in your coding agent

Give your AI coding agent this catalog as tools — so it can name the smell, find the static-analysis detectors, and apply the right refactoring or pattern while it writes code, instead of guessing.

Any MCP client (.mcp.json)

{
  "mcpServers": {
    "codebust": { "command": "npx", "args": ["-y", "codebust-mcp"] }
