Search for catalogues by keyword in their names or descriptions.
AI agents call search_catalogues to retrieve information from Data Gov My 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 information from a government data catalogue without side effects. It does not create, modify, delete, or execute any operations—it only searches and returns results. This is a classic Read category tool with minimal risk.
From the tool's definition Tool performs a search operation on catalogue names and descriptions to retrieve matching results. The verb "search" and the read-only nature of querying metadata indicate no data modification, deletion, or execution of external operations.
Documented attack patterns abuse exactly the kind of access search_catalogues gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Data Gov My MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_catalogues:
{
"version": "1",
"default": "deny",
"tools": {
"search_catalogues": {}
}
}search_catalogues is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Yes. Add a rate_limit block to the search_catalogues 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 search_catalogues. 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.
search_catalogues is provided by the Data Gov My MCP Server MCP server (manfye/data-dosm-mcp-nodejs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
