Code Vulnerability Scanner
The Code Security Scanner MCP server lets developers scan code snippets for vulnerabilities like SQL injection, hardcoded secrets, and unsafe deserialization using the scan_code tool's offline heuristic rules. Test connectivity with the hello tool's greeting or echo inputs for quick verification. Conduct private code analysis without internet access or external services.
Overview
The Code Security Scanner MCP server delivers a specialized code analysis tool that detects security vulnerabilities and risky patterns in code snippets. Powered by offline heuristic rules, it flags issues like SQL injection, hardcoded secrets, command injection, weak cryptography, path traversal, and unsafe deserialization—without internet access or external APIs—for fast, private scans right in your development environment.
Key Capabilities
- hello: Returns a greeting message to confirm server connectivity and tool availability.
- echo: Mirrors input text to test request handling and debug interactions.
- scan_code: Examines code snippets in languages like Python, JavaScript, Java, or C++ for vulnerabilities. Delivers a detailed report with issue descriptions, severity ratings (low/medium/high), line numbers, and remediation steps, such as using prepared statements for SQL queries or avoiding eval().
Use Cases
- Pre-commit review: Paste a new function into scan_code to spot unescaped user input risking SQL injection, then apply the suggested fix with parameterized queries before git commit.
- Third-party vetting: Scan open-source library code for hardcoded API keys or eval() calls, extracting or replacing them safely prior to integration.
- Legacy audits: Analyze old JavaScript for XSS-prone innerHTML assignments, getting a prioritized remediation list for targeted refactoring.
- CI/CD validation: Script scan_code against pull request diffs to block merges on high-severity flaws, like C++ buffer overflows.
Who This Is For
Intermediate to advanced developers, appsec engineers, and backend programmers working with Python, JavaScript, Java, or C++. Perfect for teams or individuals embedding local vulnerability checks into code reviews, pair programming, or prototyping without external dependencies.
