semantic_log_search
AI agents call semantic_log_search to retrieve information from Lumino MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Semantic log search retrieves and queries log data without modifying or executing anything. This is a read operation consistent with observability and monitoring use cases. The lack of description lowers confidence slightly, but the name and server context (debugging/observability) strongly suggest read-only behavior.
From the tool's definition Tool name 'semantic_log_search' indicates log retrieval/querying. No description provided, but semantic search on logs is a read-only observability operation typical of SRE platforms.
Attacks that exploit this kind of access
semantic_log_search. It is categorised as a Read tool in the Lumino MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Lumino MCP Server MCP server in PolicyLayer and add a rule for semantic_log_search: 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 Lumino MCP Server. Nothing to install.
semantic_log_search 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 semantic_log_search 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 semantic_log_search. 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.
semantic_log_search is provided by the Lumino MCP Server MCP server (lumino-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
