List service environment variables
AI agents call list_service_envs to retrieve information from Coolify MCP Tools 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 existing service environment variables without modifying, creating, or deleting them. It is a read-only operation that queries data from the Coolify infrastructure management system.
From the tool's definition Tool name 'list_service_envs' and description 'List service environment variables' indicate a retrieval/query operation with no side effects.
Attacks that exploit this kind of access
List service environment variables. It is categorised as a Read tool in the Coolify MCP Tools MCP Server, which means it retrieves data without modifying state.
Register the Coolify MCP Tools MCP server in PolicyLayer and add a rule for list_service_envs: 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 MCP Tools. Nothing to install.
list_service_envs 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_service_envs 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_service_envs. 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_service_envs is provided by the Coolify MCP Tools MCP server (jplansink/coolify-mcp-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
