Provides a comprehensive overview of recent parliamentary activities, including the most recent documents and MPs celebrating birthdays today. The response contains structured data with two main sections:
AI agents call get_overview to retrieve information from OpenTK Model Context Protocol Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool purely retrieves and presents existing parliamentary data (recent documents and birthday information) without any side effects, modifications, or external actions. It fits the Read category as it queries and fetches data only. The low severity reflects that misuse would only result in unauthorized data access of public parliamentary information, with no capability to modify, delete, or cause harm.
From the tool's definition Tool name 'get_overview' and description stating it 'Provides a comprehensive overview of recent parliamentary activities' and 'The response contains structured data' with no mention of modification, deletion, execution, or financial operations.
Documented attack patterns abuse exactly the kind of access get_overview gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OpenTK Model Context Protocol Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_overview:
{
"version": "1",
"default": "deny",
"tools": {
"get_overview": {}
}
}get_overview is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Provides a comprehensive overview of recent parliamentary activities, including the most recent documents and MPs celebrating birthdays today. The response contains structured data with two main sections:. It is categorised as a Read tool in the OpenTK Model Context Protocol Server MCP Server, which means it retrieves data without modifying state.
Register the OpenTK Model Context Protocol Server MCP server in PolicyLayer and add a rule for get_overview: 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 OpenTK Model Context Protocol Server. Nothing to install.
get_overview 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_overview 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_overview. 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_overview is provided by the OpenTK Model Context Protocol Server MCP server (r-huijts/opentk-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OpenTK Model Context Protocol Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
