AI agents call table_dimensions to retrieve information from Cbs Nl without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though table_dimensions only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access table_dimensions gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Column/dimension definitions for a table (DataProperties): what each field means, its key, type, unit and decimals. Use this before get_data to learn which $select keys and $filter dimensions exist.. It is categorised as a Read tool in the Cbs Nl MCP Server, which means it retrieves data without modifying state.
Register the Cbs Nl MCP server in PolicyLayer and add a rule for table_dimensions: 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 Cbs Nl. Nothing to install.
table_dimensions 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 table_dimensions 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 table_dimensions. 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.
table_dimensions is provided by the Cbs Nl MCP server (https://gateway.pipeworx.io/cbs-nl/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
