List apps
AI agents call list-apps to retrieve information from Koyeb MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that queries and returns data about apps in the Koyeb environment. It has no side effects, does not modify state, and does not trigger external operations. This is a straightforward data retrieval function with minimal risk if misused by an AI agent.
From the tool's definition Tool name 'list-apps' and description 'List apps' indicate a query operation that retrieves a list of existing applications without modifying, deleting, or executing operations.
Attacks that exploit this kind of access
List apps. It is categorised as a Read tool in the Koyeb MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Koyeb MCP Server MCP server in PolicyLayer and add a rule for list-apps: 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 Koyeb MCP Server. Nothing to install.
list-apps 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-apps 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-apps. 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-apps is provided by the Koyeb MCP Server MCP server (samihalawa/mcp-server-koyeb). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
