Retrieves metadata about a parliamentary document in a structured JSON format, without downloading the actual document content. Returns information including title, type, document number, dates, version number, and links to both the PDF version and the official Tweede Kamer webpage.
AI agents call get_document_details 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 performs document metadata retrieval from a public parliamentary database. It has no capability to modify, execute, delete, or create data. It returns publicly available information (title, dates, document numbers, links) with no impact on system state or data integrity. The explicit statement that it does not download content confirms it is purely informational.
From the tool's definition Tool 'retrieves metadata about a parliamentary document in a structured JSON format, without downloading the actual document content.' It returns 'information including title, type, document number, dates, version number, and links' — all read-only data…
Documented attack patterns abuse exactly the kind of access get_document_details 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_document_details:
{
"version": "1",
"default": "deny",
"tools": {
"get_document_details": {}
}
}get_document_details is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieves metadata about a parliamentary document in a structured JSON format, without downloading the actual document content. Returns information including title, type, document number, dates, version number, and links to both the PDF version and the official Tweede Kamer webpage. 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_document_details: 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_document_details 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_document_details 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_document_details. 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_document_details 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.
