AI agents call search_collections to retrieve information from Smithsonian Open Access 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 or queries data from the Smithsonian's collection database without creating, modifying, deleting, or executing operations. The blast radius of misuse is minimal—an agent could only retrieve more collection information than intended, not alter or damage museum data.
From the tool's definition Tool name 'search_collections' and sibling tools (find_and_describe, find_on_view_items, get_collection_statistics, get_object_details) all indicate retrieval and querying operations.
Documented attack patterns abuse exactly the kind of access search_collections gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Smithsonian Open Access MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_collections:
{
"version": "1",
"default": "deny",
"tools": {
"search_collections": {}
}
}search_collections is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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