AI agents call scan_todos to retrieve information from Dooist without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries code comments without inherent side effects. The scanning operation is a read operation that analyzes existing codebase content. Although task creation is mentioned as optional, the tool's essential purpose—scanning for patterns in code—is fundamentally a read operation. If invoked without the optional create flag, it has no side effects.
From the tool's definition Tool description states it 'scans codebase for TODO, FIXME, HACK, and XXX comments' and 'optionally create tasks from them.' The primary action is scanning/reading code comments.
Attacks that exploit this kind of access
Scan codebase for TODO, FIXME, HACK, and XXX comments. Optionally create tasks from them. It is categorised as a Read tool in the Dooist MCP Server, which means it retrieves data without modifying state.
Register the Dooist MCP server in PolicyLayer and add a rule for scan_todos: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Dooist. Nothing to install.
scan_todos is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the scan_todos rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for scan_todos. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
scan_todos is provided by the Dooist MCP server (papermoose/dooist). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
