AI agents call list_databases 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 queries and returns database summary information without modifying, deleting, or executing any operations. It is a simple read operation with minimal blast radius if misused by an AI agent—an attacker could only discover what databases exist, not compromise them directly.
From the tool's definition Tool name is 'list_databases' and description is 'List databases (summary)' - a retrieval operation with no mutation or side effects.
Attacks that exploit this kind of access
List databases (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_databases: 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_databases 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_databases 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_databases. 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_databases 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.
