How to Set Up and Use Agnix
Agnix is a linter and language-server-protocol tool specifically designed for AI coding assistant configuration files, validating 423 rules across formats like CLAUDE.md, AGENTS.md, SKILL.md, .cursorrules, MCP JSON files, and GitHub Copilot instructions. It catches common mistakes in hooks, agent definitions, and MCP configurations before they cause silent failures, and can automatically apply fixes at configurable confidence levels. Teams that maintain complex AI agent setups across multiple assistants (Claude, Cursor, Copilot, Kiro, Cline, Gemini CLI) will benefit from having a single linter that enforces correctness across all of them.
Prerequisites
- Node.js 18 or higher (for npx usage) or Rust toolchain (for cargo install)
- An AI assistant project with configuration files such as CLAUDE.md, .mcp.json, or .cursorrules
- Claude Desktop, Claude Code, or another MCP-compatible client (for MCP integration)
- Optional: VS Code, JetBrains IDE, Neovim, or Zed for editor plugin integration
Install agnix globally
Install the agnix CLI globally via npm so it is available as a command. Alternatively use Homebrew on macOS/Linux or cargo for a Rust-native install.
npm install -g agnixRun a validation pass on your project directory
Point agnix at your project root to lint all supported AI configuration files and see any rule violations.
agnix .Preview and apply autofixes
Use --dry-run to preview what changes would be made, then apply high-confidence fixes automatically.
agnix --dry-run --show-fixes .
agnix --fix-safe .Add the agnix MCP server to your Claude config
Register the agnix MCP server so Claude can validate your configuration files on demand during a session.
{
"mcpServers": {
"agnix": {
"command": "npx",
"args": ["-y", "agnix"]
}
}
}Install the editor plugin (optional)
For inline diagnostics while editing, install the agnix extension for your IDE from the VS Code Marketplace, JetBrains Plugin Marketplace, or via your Neovim plugin manager.

}Prompts to try
Example prompts that use agnix to validate and fix AI assistant configuration files.
- "Validate my CLAUDE.md and hooks configuration and list any rule violations."
- "Check my .mcp.json for MCP configuration errors and suggest fixes."
- "Run agnix in strict mode on this project and treat all warnings as errors."
- "Apply safe autofixes to my AGENTS.md and show me a diff of the changes."
- "Validate my Cursor configuration files and compare against Claude Code rules."Troubleshooting Agnix
agnix reports 'command not found' after global npm install.
Ensure the npm global bin directory is on your PATH. Run `npm bin -g` to find it and add it to your shell profile, or use `npx agnix .` as an alternative.
Rules fire on files that should be excluded from linting.
Use the `--target` flag to limit validation to a specific assistant preset, e.g. `agnix --target claude-code .` to only apply Claude Code rules.
Autofixes break valid configuration that agnix misidentifies as wrong.
Use `--fix-safe` instead of `--fix` to apply only high-confidence fixes, and always preview with `--dry-run --show-fixes` before applying changes to production configs.
