AI agents call list_services to retrieve information from Packmate without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about existing services without creating, modifying, deleting, or executing any operations. It is a straightforward read operation that retrieves configuration data. The low severity reflects minimal risk if misused by an AI agent—disclosure of service names poses no direct harm to system integrity.
From the tool's definition Tool name 'list_services' and description 'List all configured Packmate services' indicate a retrieval operation with no data modification or side effects.
Attacks that exploit this kind of access
List all configured Packmate services. It is categorised as a Read tool in the Packmate MCP Server, which means it retrieves data without modifying state.
Register the Packmate MCP server in PolicyLayer and add a rule for list_services: 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 Packmate. Nothing to install.
list_services 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_services 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_services. 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_services is provided by the Packmate MCP server (umbra2728/packmate-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
