Get detailed information about a specific dataset
AI agents call get_dataset_details to retrieve information from Hong Kong Open Data 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 queries data from Hong Kong's public open data portal without side effects. It falls squarely into the Read category as it only fetches metadata about datasets. The severity is low because the tool accesses public, non-sensitive government data with no risk of data modification, financial impact, or code execution. Confidence is high given the clear read-only semantics and public data context.
From the tool's definition Tool name is 'get_dataset_details' and description states 'Get detailed information about a specific dataset'.

PolicyLayer is an MCP gateway — it sits between your AI agents and Hong Kong Open Data MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_dataset_details:
{
"version": "1",
"default": "deny",
"tools": {
"get_dataset_details": {}
}
}get_dataset_details is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get detailed information about a specific dataset. It is categorised as a Read tool in the Hong Kong Open Data MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Hong Kong Open Data MCP Server MCP server in PolicyLayer and add a rule for get_dataset_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 Hong Kong Open Data MCP Server. Nothing to install.
get_dataset_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_dataset_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_dataset_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_dataset_details is provided by the Hong Kong Open Data MCP Server MCP server (mcp-open-data-hk/mcp-open-data-hk). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Hong Kong Open Data MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
