AI Code Safety for the MCP Era: Introducing ailinter

ailinteris a lightweight, local security and quality tool designed specifically for the Model Context Protocol (MCP) era. It scans AI-generated code for quality issues, hardcoded secrets, and security vulnerabilities before they reach production. Built natively for MCP, it works seamlessly with AI coding assistants like Claude, OpenCode, Cursor, Continue.dev, and Zed.

Benefits

• Local and Fast:ailinter runs entirely on your computer. It does not need an internet connection or cloud servers. It is very small, weighing only 15MB.
• Zero Setup:You do not need to create an account or sign up for anything. It requires no external dependencies to run.
• Comprehensive Scanning:It combines three powerful engines into one tool. It checks code quality, finds hidden secrets like passwords, and detects security vulnerabilities.
• AI-Friendly Guidance:It provides specific advice on how to fix code issues. It gives a score from 0 to 100 for every file to tell you if the code is ready or needs work.
• Cost Saving:It can estimate how many tokens an AI model will use for a file. This helps you save money by avoiding expensive code reviews.
• Privacy First:All detected secrets are hidden in the output. This ensures that sensitive information never leaks to the AI context.

Use Cases

• AI Code Review:Developers can use ailinter to review code generated by AI assistants before they commit it to a project.
• Secret Detection:Teams can use it to find accidentally exposed API keys, passwords, or tokens in their codebase.
• Security Auditing:It helps identify common security flaws like injection errors or weak encryption in Python, Go, JavaScript, Java, C#, and PHP.
• Code Quality Assurance:It helps maintain high standards by flagging complex logic, long functions, and repetitive code patterns.
• CI Integration:It can be used in continuous integration pipelines to enforce code coverage thresholds and ensure maintainability.

Pricing

ailinter is free to use. It is open source under the MIT license. There is no cost for installation or basic usage.

Vibes

Users appreciate that the tool is lightweight and requires no signup. The community values its ability to work directly with popular AI coding tools without needing a cloud dependency. Many developers find the token estimation feature helpful for managing costs when using AI for coding.
