Fetch one Tweede Kamer record by its GUID id. Pass the entity name and the record Id (a GUID, e.g. "8b3664bd-77e4-468b-af96-f3f4ec27fcce"). Optionally narrow fields with $select or inline related records with $expand.

AI agents call get_entity_by_id to retrieve information from Tweedekamer 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 get_entity_by_id 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 get_entity_by_id 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.
Fetch one Tweede Kamer record by its GUID id. Pass the entity name and the record Id (a GUID, e.g. "8b3664bd-77e4-468b-af96-f3f4ec27fcce"). Optionally narrow fields with $select or inline related records with $expand.. It is categorised as a Read tool in the Tweedekamer Nl MCP Server, which means it retrieves data without modifying state.
Register the Tweedekamer Nl MCP server in PolicyLayer and add a rule for get_entity_by_id: 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 Tweedekamer Nl. Nothing to install.
get_entity_by_id 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 get_entity_by_id 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 get_entity_by_id. 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.
get_entity_by_id is provided by the Tweedekamer Nl MCP server (https://gateway.pipeworx.io/tweedekamer-nl/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
