Semgrep MCP Server

A Model Context Protocol (MCP) server that brings the power of Semgrep's static analysis capabilities directly into your AI-assisted development workflow. This server enables seamless integration with Semgrep's code scanning and security analysis tools, allowing you to identify bugs, detect security vulnerabilities, and enforce code standards without leaving your development environment.

Overview

The Semgrep MCP server acts as a bridge between MCP-compatible AI assistants and Semgrep's comprehensive static analysis engine. By exposing Semgrep's functionality through the Model Context Protocol, this server enables natural language interactions with one of the industry's most powerful code analysis tools.

What It Does

This server provides direct access to Semgrep's core functionality, allowing you to:

• Scan codebases for security vulnerabilities, bugs, and code quality issues
• Run custom rules to enforce organization-specific coding standards and patterns
• Execute targeted scans on specific files, directories, or entire projects
• Retrieve scan results in a structured format that's easy to understand and act upon
• Access Semgrep's rule registry to leverage thousands of community-maintained detection patterns

Key Features

Comprehensive Code Analysis

Perform static analysis across multiple programming languages and frameworks. The server supports Semgrep's extensive language coverage, enabling you to maintain consistent code quality standards across diverse technology stacks.

Security Vulnerability Detection

Identify security issues early in the development cycle by running OWASP Top 10 checks, detecting injection flaws, authentication problems, and other common security vulnerabilities that could compromise your application.

Custom Rule Execution

Apply your own Semgrep rules or leverage the extensive rule registry to enforce team-specific patterns, catch anti-patterns, and maintain architectural consistency across your codebase.

Flexible Scanning Options

Configure scans with various parameters including rule sets, file paths, severity levels, and output formats to match your specific analysis needs.

Use Cases

Security Auditing: Quickly scan code for known vulnerabilities and security anti-patterns before committing changes or during code review processes.

Code Quality Enforcement: Automatically check for code smells, deprecated patterns, and violations of team coding standards.

Compliance Verification: Ensure code adheres to regulatory requirements and industry best practices through automated policy enforcement.

Technical Debt Management: Identify areas of technical debt and prioritize refactoring efforts based on concrete analysis results.

Why Use This Server

Integrating Semgrep through MCP creates a powerful combination where AI assistance meets rigorous static analysis. Instead of switching between tools or manually running command-line scans, you can request code analysis naturally and receive actionable insights immediately. This streamlined workflow helps you catch issues earlier, maintain higher code quality, and ship more secure software faster.
