Checks if a dataset is available via CBS OData (queryable) or data.overheid.nl (download-only).
AI agents call cbs_check_dataset_availability to retrieve information from Nl Opendata without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about dataset availability status. It does not execute queries, modify data, delete anything, or trigger external operations. It simply checks and reports the current availability state of datasets, which is a pure read operation with minimal blast radius if misused.
From the tool's definition Tool performs availability checking which is a status query operation; the description explicitly states it only checks if datasets are 'available via CBS OData (queryable) or data.overheid.nl (download-only)' — this is a lookup/inspection with no…
Attacks that exploit this kind of access
Checks if a dataset is available via CBS OData (queryable) or data.overheid.nl (download-only). It is categorised as a Read tool in the Nl Opendata MCP Server, which means it retrieves data without modifying state.
Register the Nl Opendata MCP server in PolicyLayer and add a rule for cbs_check_dataset_availability: 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 Nl Opendata. Nothing to install.
cbs_check_dataset_availability 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 cbs_check_dataset_availability 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 cbs_check_dataset_availability. 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.
cbs_check_dataset_availability is provided by the Nl Opendata MCP server (soulnai/nl-opendata-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
