List all known agents and their availability on this system.
AI agents call list_agents to retrieve information from Agent Link without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about agents and their status without creating, modifying, deleting, or executing any operations. It is a read-only informational query with minimal security risk.
From the tool's definition Tool name 'list_agents' and description 'List all known agents and their availability on this system' indicate a query/retrieval operation with no data modification or side effects.
Attacks that exploit this kind of access
List all known agents and their availability on this system. It is categorised as a Read tool in the Agent Link MCP Server, which means it retrieves data without modifying state.
Register the Agent Link MCP server in PolicyLayer and add a rule for list_agents: 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 Link. Nothing to install.
list_agents 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 list_agents 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 list_agents. 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.
list_agents is provided by the Agent Link MCP server (mikusnuz/agent-link-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
