WHAT IT DOES

What search_products does on Filtrous MCP Catalog Server

Parameter	Type	Required	Description
`limit`	integer	—	Max results (default 10).
`query`	string	Yes	Free-text and/or spec search. Field filters like 'product_type:...' or 'tag:...' are also honored.

Parameters from the server's own tool schema.

RISK

Why search_products is rated Low

search_products is a catalog query that retrieves product information without creating, modifying, deleting, or executing any operations. The ability to search and view product specifications, pricing, and availability is a read-only data retrieval function with no side effects or blast radius if an AI agent misuses it.

From the tool's definition Tool 'searches' the catalog and 'returns matching products' — retrieves product data with no modification capability.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs search_products safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Filtrous MCP Catalog Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For search_products, this is the rule to start with:

search_products Allowed

search_products is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_products": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Filtrous MCP Catalog Server, apply this rule, and every search_products call is checked against it from then on.
