Search for assets on Polyhaven with optional filtering. Parameters: - asset_type: Type of assets to search for (hdris, textures, models, all) - categories: Optional comma-separated list of categories to filter by Returns a list of matching assets with basic information.
AI agents call search_polyhaven_assets to retrieve information from Tripo MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward query/search tool that retrieves data from Polyhaven without side effects. It fits the Read category definition: 'retrieves or queries data; no side effects'. The low severity reflects minimal risk from misuse—an agent could at worst perform redundant searches, wasting resources but causing no harm to data or systems.
From the tool's definition Tool performs a search operation that returns asset information; the description explicitly states it 'returns a list of matching assets' with no mention of modification, deletion, or execution capabilities.
Documented attack patterns abuse exactly the kind of access search_polyhaven_assets gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Tripo MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_polyhaven_assets:
{
"version": "1",
"default": "deny",
"tools": {
"search_polyhaven_assets": {}
}
}search_polyhaven_assets is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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