Gets detailed information about a Swift Package Manager package.
AI agents call get_package_info to retrieve information from Xcode without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries metadata about a Swift package without modifying, executing, or deleting any data. It has no side effects and poses minimal risk if misused by an AI agent, as the worst outcome would be gathering information about available packages.
From the tool's definition Tool name 'get_package_info' and description 'Gets detailed information about a Swift Package Manager package' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_package_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Xcode, and nothing reaches the server without passing your rules. This is the rule we recommend for get_package_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_package_info": {}
}
}get_package_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Gets detailed information about a Swift Package Manager package. It is categorised as a Read tool in the Xcode MCP Server, which means it retrieves data without modifying state.
Register the Xcode MCP server in PolicyLayer and add a rule for get_package_info: 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 Xcode. Nothing to install.
get_package_info 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 get_package_info 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 get_package_info. 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.
get_package_info is provided by the Xcode MCP server (xcode-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
