AI agents call list_servers to retrieve information from Coolify without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays a summary of servers without modifying, deleting, or executing any operations. It is purely informational, matching the Read category definition of data retrieval/queries with no side effects. Low severity because listing servers exposes infrastructure inventory but does not enable direct harm unless the attacker uses it for reconnaissance before executing another tool.
From the tool's definition Tool name 'list_servers' and description 'List servers (summary)' indicate a data retrieval operation with no side effects.
Attacks that exploit this kind of access
List servers (summary). It is categorised as a Read tool in the Coolify MCP Server, which means it retrieves data without modifying state.
Register the Coolify MCP server in PolicyLayer and add a rule for list_servers: 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 Coolify. Nothing to install.
list_servers 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_servers 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_servers. 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_servers is provided by the Coolify MCP server (jurislm/coolify-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Every MCP server has a record like this.
