AI agents call get_properties to retrieve information from Wikidata MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to retrieve or query property data from Wikidata without modifying, deleting, or executing code. While the empty description lowers confidence slightly, the naming convention and server context (metadata extraction) strongly indicate a Read operation with minimal blast radius if misused.
From the tool's definition Tool name 'get_properties' and sibling tools (search_entity, search_property, get_metadata, execute_sparql) indicate this is a data retrieval function.
Documented attack patterns abuse exactly the kind of access get_properties gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Wikidata MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_properties:
{
"version": "1",
"default": "deny",
"tools": {
"get_properties": {}
}
}get_properties is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_properties. It is categorised as a Read tool in the Wikidata MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Wikidata MCP Server MCP server in PolicyLayer and add a rule for get_properties: 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 Wikidata MCP Server. Nothing to install.
get_properties 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_properties 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_properties. 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_properties is provided by the Wikidata MCP Server MCP server (zzaebok/mcp-wikidata). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
