Mobb Vibe Shield (MVS)
What is Mobb Vibe Shield?
Mobb Vibe Shield (MVS) is a tool your IDE AI assistant can call to identify and fix security vulnerabilities directly in the editor, as you work.
MVS operates via the Model Context Protocol (MCP), allowing it to interact with IDE-integrated AI agents such as GitHub Copilot, Cursor, and others. It supports both scanning and fixing, as well as remote fix retrieval from the Mobb platform.

Modes
Mobb Vibe Shield supports three primary modes:
1. scan_and_fix_vulnerabilities
scan_and_fix_vulnerabilities
Scans recently modified files in your local project and applies fixes inline.
If there are uncommitted changes, MVS scans the last 3 modified files.
If there are no uncommitted changes, it scans files from the previous commit.
If the project is not a Git repository, it scans the 3 most recently modified files by timestamp.
Scanning is powered by OpenGrep.
Here is a demo of the scan_and_fix_vulnerabilities
mode in action:
2. fetch_available_fixes
fetch_available_fixes
Checks whether the current repository has a matching fix report in the Mobb platform (e.g., from CI/CD pipelines or prior manual uploads) and applies those fixes to local files.
Here is a demo of the fetch_available_fixes
Mode in action:
3. check_for_new_available_fixes
check_for_new_available_fixes
This mode triggers a continuous monitoring mode where MVS will scan and monitor for available fixes in your project. The first call to this tool starts the scan, and from then on, MVS will automatically scan for new fixes every 15 minutes. This ensures you are always notified of the latest security fixes as soon as they become available.
To use this mode effectively, you should add a rulebook to your IDE that instructs the agent to always call check_for_new_available_fixes
at the end of each session. For example, in VS Code or Cursor, you can create a rulebook file (such as .github/copilot-instructions.md
or mvs.mdc
) that includes instructions to always invoke this tool after completing all code changes. For more information on how to deploy rulebooks, see VS Code guide or Cursor guide.
