What lastReadAt does on GitHub
AI agents call lastReadAt to retrieve information from GitHub without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why lastReadAt is rated Low
This tool queries a metadata value about notification state without creating, modifying, deleting, or executing any operations. It is a pure read operation with minimal blast radius if misused by an agent.
From the tool's definition Tool name 'lastReadAt' and description indicate it retrieves or queries the timestamp of the last notification check—a data retrieval operation with no side effects. The term 'describes' and the optional parameter nature confirm this is inspection-only.
Attacks that exploit this kind of access
The rule that runs lastReadAt safely
PolicyLayer is an MCP gateway: it sits between your AI agents and GitHub, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For lastReadAt, this is the rule to start with:
lastReadAt is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect GitHub, apply this rule, and every lastReadAt call is checked against it from then on.
