Perform statistical analysis on a dataset.
AI agents call analyze_dataset 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.
Statistical analysis inherently queries and processes data to produce summaries and insights without side effects. No data is created, modified, deleted, or executed. The tool is part of a public open-data query server, and statistical operations are purely informational. Confidence is high because the description unambiguously describes a read operation.
From the tool's definition The tool 'analyze_dataset' performs statistical analysis, which is a read-only operation that retrieves and computes metrics on existing data without modifying, deleting, or executing external operations.
Attacks that exploit this kind of access
Perform statistical analysis on a dataset. 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 analyze_dataset: 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.
analyze_dataset 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 analyze_dataset 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 analyze_dataset. 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.
analyze_dataset 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.
