Find MPs, bills, petitions, or declared financial interests.
AI agents call find_entities to retrieve information from UK Parliament MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and searches parliamentary data (MPs, bills, petitions, financial interests) without side effects. It is a read-only query operation. While the data accessed (financial interests, voting records) is sensitive, the tool itself performs no destructive, financial, or executable actions. Severity is low because misuse would only enable information gathering rather than system compromise or data loss.
From the tool's definition Tool description states 'Find MPs, bills, petitions, or declared financial interests' — pure retrieval operations with no modification or execution. No deletion, financial transactions, or code execution mentioned.
Documented attack patterns abuse exactly the kind of access find_entities gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and UK Parliament MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for find_entities:
{
"version": "1",
"default": "deny",
"tools": {
"find_entities": {}
}
}find_entities is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

find_entities 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 find_entities 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 find_entities. 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.
find_entities is provided by the UK Parliament MCP Server MCP server (kupad95/uk-parliament-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from UK Parliament MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
