Get the build or runtime logs
AI agents call query-logs 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 log information (build or runtime logs) from Koyeb deployments, which is a read operation with no side effects. However, logs may contain sensitive information (API keys, credentials, environment variables, internal architecture details), making exposure of this capability potentially valuable to an attacker, warranting a medium severity rating rather than low.
From the tool's definition Tool description: 'Get the build or runtime logs' - retrieves log data without modifying resources.
Attacks that exploit this kind of access
Get the build or runtime logs. 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 query-logs: 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.
query-logs 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 query-logs 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 query-logs. 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.
query-logs 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.
