Check for tasks assigned to an agent
AI agents call check_tasks to retrieve information from Agent Communication MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries existing task assignments for an agent, producing no side effects. It retrieves information to monitor workflow status, consistent with the server's transparency and monitoring goals. No data is created, modified, deleted, or externally executed.
From the tool's definition Tool name 'check_tasks' and description 'Check for tasks assigned to an agent' indicate a query operation that retrieves task information without modifying state.
Attacks that exploit this kind of access
Check for tasks assigned to an agent. It is categorised as a Read tool in the Agent Communication MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Agent Communication MCP Server MCP server in PolicyLayer and add a rule for check_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 Agent Communication MCP Server. Nothing to install.
check_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 check_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 check_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.
check_tasks is provided by the Agent Communication MCP Server MCP server (jerfowler/agent-comm-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
