What adb_screenshot_baseline does on Deepadb
AI agents use adb_screenshot_baseline to create or update resources in Deepadb, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Deepadb environment.
Why adb_screenshot_baseline is rated Medium
This tool captures a screenshot and saves it along with metadata to a directory on the filesystem. It creates/writes new files (baseline image and metadata), which is a reversible write operation. It does not delete data or execute arbitrary code, making Write the appropriate category.
From the tool's definition Capture a named screenshot baseline... Saves the screenshot and metadata to the baselines directory
Attacks that exploit this kind of access
The rule that runs adb_screenshot_baseline safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Deepadb, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For adb_screenshot_baseline, this is the rule to start with:
adb_screenshot_baseline stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Deepadb, apply this rule, and every adb_screenshot_baseline call is checked against it from then on.
