WHAT IT DOES

What tk-query does on Meta Data Mcp

AI agents call tk-query to retrieve information from Meta Data Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why tk-query is rated Low

This tool retrieves data from the Tweedekamer (Dutch parliament) open data API using OData query parameters. OData is a standardized protocol for read access to data sources. There is no indication of write, delete, execute, or financial operations. The tool fits squarely in the Read category with low severity since it accesses public government data without side effects.

From the tool's definition Tool name 'tk-query' and description 'Query a Tweedekamer entity set using OData v4 parameters' indicate a data retrieval operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs tk-query safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Meta Data Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For tk-query, this is the rule to start with:

tk-query Allowed

tk-query is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "tk-query": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Meta Data Mcp, apply this rule, and every tk-query call is checked against it from then on.
