Search for datasets in the Utsunomiya Open Data Catalog.
AI agents call search_datasets to retrieve information from Utsunomiya without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches through existing public datasets in Utsunomiya's open data catalog. It retrieves information about available datasets without modifying, executing, or deleting any data. The operation has no side effects and falls squarely into the Read category with low severity—even if an AI agent misuses the search, it can only discover datasets already publicly available.
From the tool's definition Tool performs 'Search for datasets' in a catalog, which is a query/retrieval operation with no modification or execution of code. Description indicates catalog browsing functionality.
Attacks that exploit this kind of access
Search for datasets in the Utsunomiya Open Data Catalog. It is categorised as a Read tool in the Utsunomiya MCP Server, which means it retrieves data without modifying state.
Register the Utsunomiya MCP server in PolicyLayer and add a rule for search_datasets: 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 Utsunomiya. Nothing to install.
search_datasets 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_datasets 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_datasets. 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_datasets is provided by the Utsunomiya MCP server (takurot/utsunomiya-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
