Get a folder by ID, including metadata and content counts.
AI agents call get_folder to retrieve information from Looker 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 query to retrieve folder metadata and content statistics. It does not create, modify, delete, or execute anything. The narrow scope (fetching by ID only) and informational nature of the response limit the blast radius if misused by an AI agent to low severity.
From the tool's definition The tool name is 'get_folder' and the description states it 'Get[s] a folder by ID, including metadata and content counts.' This is a retrieval operation with no side effects.
Attacks that exploit this kind of access
Get a folder by ID, including metadata and content counts. It is categorised as a Read tool in the Looker MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Looker MCP Server MCP server in PolicyLayer and add a rule for get_folder: 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 Looker MCP Server. Nothing to install.
get_folder 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_folder 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_folder. 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_folder is provided by the Looker MCP Server MCP server (ultrathink-solutions/looker-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
