Semgrep Overview

The semgrep/semgrep MCP server connects an MCP client with Semgrep’s local static-analysis engine for code scanning. Semgrep searches source code with semantic patterns, supports 30+ languages, and can run custom queries or security-focused checks. Reach for it when an agent needs to inspect a codebase for bugs, vulnerabilities, or coding-standard violations without uploading code by default.

Primary Use Cases for Semgrep:

Scan a repository for security vulnerabilities
Check source code for likely bugs
Run custom semantic code queries
Enforce coding standards in CI
