Get activity status for all online agents
AI agents call agent_activity to retrieve information from Mcp Coordinator 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 information about the current status of online agents. There are no indications that it creates, modifies, deletes, executes code, or commits financial obligations. The blast radius if misused is minimal—an agent obtaining status information about other agents poses negligible risk compared to tools that can modify coordination state or affect actual file operations.
From the tool's definition Tool name 'agent_activity' and description 'Get activity status for all online agents' indicate a retrieval operation with no side effects. The verb 'Get' and the focus on querying status information confirm this is a read-only action.
Attacks that exploit this kind of access
Get activity status for all online agents. It is categorised as a Read tool in the Mcp Coordinator MCP Server, which means it retrieves data without modifying state.
Register the Mcp Coordinator MCP server in PolicyLayer and add a rule for agent_activity: 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 Mcp Coordinator. Nothing to install.
agent_activity 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 agent_activity 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 agent_activity. 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.
agent_activity is provided by the Mcp Coordinator MCP server (swoofer/mcp-coordinator). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
