search_logs
AI agents call search_logs to retrieve information from Loki MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Although the tool description is empty, the context from the server description and sibling tools (get_pod_logs, get_error_summary, find_pod_restarts, list_namespaces) all clearly indicate read-only operations. The tool performs log searching/retrieval which has no side effects on the cluster.
From the tool's definition Tool is part of Loki MCP Server which 'enables AI models to query and analyze Kubernetes cluster logs' with 'regex-based log searching'.
Attacks that exploit this kind of access
search_logs. It is categorised as a Read tool in the Loki MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Loki MCP Server MCP server in PolicyLayer and add a rule for search_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 Loki MCP Server. Nothing to install.
search_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 search_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 search_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.
search_logs is provided by the Loki MCP Server MCP server (mvs5465-test/loki-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
