AI agents call task_summary to retrieve information from Lockstep without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves aggregate statistics about task statuses without modifying, executing, or deleting any data. It is a straightforward query operation with minimal risk even if misused by an AI agent, as it cannot alter system state.
From the tool's definition Tool name 'task_summary' and description 'Get task counts by status' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Get task counts by status. Lighter than task_list - use when you just need to know how many tasks are in each state. It is categorised as a Read tool in the Lockstep MCP Server, which means it retrieves data without modifying state.
Register the Lockstep MCP server in PolicyLayer and add a rule for task_summary: 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 Lockstep. Nothing to install.
task_summary 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 task_summary 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 task_summary. 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.
task_summary is provided by the Lockstep MCP server (tmmoore286/lockstep-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
