AppSec for the Agentic Era

Semgrep is the only AppSec platform built for the agentic era of software development. We’re not duct-taping legacy security tools to LLMs — we’re rethinking what secure development should look like when your pair programmer is a language model.

Semgrep doesn't just wrap ChatGPT and prompt - our products give LLMs structured access to Semgrep's engine capabilities. If a model gets 1% better at a security task, we want it to get 10% better when plugged into Semgrep.

Our open-source Model Context Protocol (MCP) for Semgrep works with any IDE based MCP client, like Cursor. With our MCP server, LLMs can use Semgrep as a tool to quickly find and fix security issues in the code they generate.

Vibe code safely with Replit & Semgrep

Builders using Replit can turn on the new pre-deployment scanning feature, which lets Replit Agent run a Semgrep scan to automatically find security issues via a curated set of Python, Javascript, and Typescript rules.

Building with AI?
