Semgrep Guardian: Claude Code Plugin

Installation instructions:

1. Start a Claude Code instance by running:

   claude
   

2. Add the Semgrep marketplace by running the following command in Claude:

   /plugin marketplace add semgrep/guardian
   

3. Install the plugin from the marketplace:

   /plugin install semgrep@semgrep-marketplace
   

4. Tell claude to load the plugin:

   /reload-plugins
   

5. Ask claude to login to semgrep, using the guardian mcp

   login to semgrep
   

   This should call into the MCP, but if claude is having trouble, call /clear to restart claude, or exit and reopen claude manually.
