AI agents call get_blocked_tasks to retrieve information from Todos without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries task data to identify blocked tasks based on dependency status. It performs a read-only query with no side effects, no data modification, and no external command execution. The verb 'Get' combined with the passive state description confirms it is a Read operation.
From the tool's definition Tool name 'get_blocked_tasks' and description 'Get tasks that are blocked by incomplete dependencies' indicate a retrieval operation with no modification or execution of external operations.
Attacks that exploit this kind of access
Get tasks that are blocked by incomplete dependencies. It is categorised as a Read tool in the Todos MCP Server, which means it retrieves data without modifying state.
Register the Todos MCP server in PolicyLayer and add a rule for get_blocked_tasks: 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 Todos. Nothing to install.
get_blocked_tasks 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 get_blocked_tasks 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 get_blocked_tasks. 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.
get_blocked_tasks is provided by the Todos MCP server (@hasna/todos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
