Get cache statistics and list all cached datasets.
AI agents call cache_info to retrieve information from Ontario Data without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns information about cached data. It performs no side effects, makes no modifications, executes no code, and cannot delete or move money. The blast radius of misuse is minimal—an agent could only over-query cache metadata or learn about dataset names and sizes already known to the system.
From the tool's definition Tool retrieves cache statistics and lists cached datasets. The verbs 'get' and 'list' indicate read-only operations with no modification or execution of external commands.
Attacks that exploit this kind of access
Get cache statistics and list all cached datasets. It is categorised as a Read tool in the Ontario Data MCP Server, which means it retrieves data without modifying state.
Register the Ontario Data MCP server in PolicyLayer and add a rule for cache_info: 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 Ontario Data. Nothing to install.
cache_info 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 cache_info 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 cache_info. 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.
cache_info is provided by the Ontario Data MCP server (sprine/ontario-data-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
