Find all datasets that contain geospatial resources (SHP, KML, GeoJSON).
AI agents call list_geo_datasets 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 retrieves or queries information about available geospatial datasets without creating, modifying, deleting, or executing any operations. It is a read-only discovery function analogous to 'list' operations.
From the tool's definition Tool name 'list_geo_datasets' and description 'Find all datasets that contain geospatial resources' indicate a query/discovery operation with no side effects.
Attacks that exploit this kind of access
Find all datasets that contain geospatial resources (SHP, KML, GeoJSON). 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 list_geo_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 Ontario Data. Nothing to install.
list_geo_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 list_geo_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 list_geo_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.
list_geo_datasets 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.
