AI agents call search_datasets to retrieve information from ModelScope MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Search tools retrieve or query data without side effects. This falls squarely into the Read category. Severity is low because searching datasets poses minimal risk—it accesses existing information without modification, deletion, or execution of arbitrary code.
From the tool's definition Tool name 'search_datasets' indicates a search operation, which is a read-only query. The sibling tools (search_mcp_servers, search_models, search_papers) are all search functions that retrieve data without modification.
Documented attack patterns abuse exactly the kind of access search_datasets gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ModelScope MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_datasets:
{
"version": "1",
"default": "deny",
"tools": {
"search_datasets": {}
}
}search_datasets is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

search_datasets. It is categorised as a Read tool in the ModelScope MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ModelScope MCP Server MCP server in PolicyLayer and add a rule for search_datasets: 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 ModelScope MCP Server. Nothing to install.
search_datasets 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 search_datasets 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_datasets. 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_datasets is provided by the ModelScope MCP Server MCP server (modelscope/modelscope-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from ModelScope MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
