AI agents call xcode_get_swift_symbols 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 parses and returns Swift language symbols from a project. It performs static analysis to extract type and member information, which is a read-only operation that queries existing code structure without side effects, modifications, or execution. No data is created, deleted, or modified, and no code is executed. This is analogous to an IDE's symbol browser or outline view.
From the tool's definition 'Extract Swift symbols (classes, structs, enums, protocols, functions, properties)' indicates retrieval of metadata about code structure without modification or execution.
Attacks that exploit this kind of access
Extract Swift symbols (classes, structs, enums, protocols, functions, properties). 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 xcode_get_swift_symbols: 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.
xcode_get_swift_symbols 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 xcode_get_swift_symbols 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 xcode_get_swift_symbols. 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.
xcode_get_swift_symbols is provided by the Xcode MCP server (raunaksplanet/xcode-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
