Unified search across both HIG design guidelines and technical documentation
AI agents call search_unified to retrieve information from Apple Dev MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches and retrieves existing documentation and guidelines. It does not create, modify, delete, or execute any operations. The only potential information exposure is to documentation that Apple has already made available to developers, with no capacity to alter data or trigger external systems. This is a standard Read category tool with minimal security risk.
From the tool's definition Tool name is 'search_unified' and description states it performs 'Unified search across both HIG design guidelines and technical documentation' — purely a retrieval/query operation with no side effects.
Documented attack patterns abuse exactly the kind of access search_unified gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Apple Dev MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_unified:
{
"version": "1",
"default": "deny",
"tools": {
"search_unified": {}
}
}search_unified is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Unified search across both HIG design guidelines and technical documentation. It is categorised as a Read tool in the Apple Dev MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Apple Dev MCP Server MCP server in PolicyLayer and add a rule for search_unified: 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 Apple Dev MCP Server. Nothing to install.
search_unified 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_unified 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_unified. 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_unified is provided by the Apple Dev MCP Server MCP server (tmaasen/apple-dev-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Apple Dev MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
