THE RISK

Low Risk

Why search_design_patterns needs a policy

This is a straightforward search operation that retrieves information about design patterns and UI components from a memory system. It has no side effects, cannot modify data, and poses minimal risk if misused by an AI agent. The action is read-only in nature.

From the tool's definition Tool name 'search_design_patterns' and description 'Search for design patterns and UI components' indicate a query/retrieval operation with no modification of data.

POLICY

How to control search_design_patterns

PolicyLayer is an MCP gateway — it sits between your AI agents and SAM, and nothing reaches the server without passing your rules. This is the rule we recommend for search_design_patterns:

policy.json

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

search_design_patterns is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register SAM — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about search_design_patterns

What does the search_design_patterns tool do? +

Search for design patterns and UI components. It is categorised as a Read tool in the SAM MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on search_design_patterns? +

Register the SAM MCP server in PolicyLayer and add a rule for search_design_patterns: 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 SAM. Nothing to install.

What risk level is search_design_patterns? +

search_design_patterns is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit search_design_patterns? +

Yes. Add a rate_limit block to the search_design_patterns 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.

How do I block search_design_patterns completely? +

Set action: deny in the PolicyLayer policy for search_design_patterns. 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.

What MCP server provides search_design_patterns? +

search_design_patterns is provided by the SAM MCP server (pigrieco/mcp-memory-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every SAM tool call.

Start from SAM, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
