AI agents call dump_swift_package 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 reads and serializes the Package.swift manifest file into JSON format. It only retrieves/reads existing data with no side effects, modifications, or destructive actions.
From the tool's definition Dumps the Package.swift manifest as JSON
Documented attack patterns abuse exactly the kind of access dump_swift_package 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 dump_swift_package:
{
"version": "1",
"default": "deny",
"tools": {
"dump_swift_package": {}
}
}dump_swift_package is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Dumps the Package.swift manifest as JSON. 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 dump_swift_package: 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.
dump_swift_package 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 dump_swift_package 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 dump_swift_package. 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.
dump_swift_package 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.
