This server can change things — files, a browser, a database, or paid online services. Limit what it can reach.
Why: writes or deletes files; queries a database.

How to use it safely
- ✓ Point it at one project folder, never your home directory or a whole drive.
- ✓ Only give it the folders it needs; files it reads can end up in the AI’s context.
- ✓ Give it a read-only database user unless writes are required.
- ✓ Pin the version (below) so an update can't change what it does without you noticing.
Code patterns worth reviewing
Automated pattern matches in the published package. Some are expected for this kind of server, and some may be false positives — they are pointers for review, not confirmed vulnerabilities.
External content fed into the prompt without isolation
The agent pulls in outside content (web pages, emails, retrieved documents) and adds it to its prompt, with no visible marking of that content as untrusted data.
