Get an app by its id
AI agents call get-app 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 retrieves information about a Koyeb app resource by its identifier. It performs a query operation without modifying, deleting, or executing any resources. The blast radius is minimal—only information disclosure of app metadata is possible if misused by an agent. This is a straightforward Read operation.
From the tool's definition Tool name 'get-app' and description 'Get an app by its id' indicate a retrieval operation with no side effects. The verb 'Get' and action of fetching an app by identifier are characteristic of read-only queries.
Attacks that exploit this kind of access
Get an app by its id. 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 get-app: 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.
get-app 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 get-app 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 get-app. 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.
get-app 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.
