AI agents call swift_get_file_imports to retrieve information from SwiftLens without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs static analysis to extract and return import statements from Swift source files. It reads file content to identify imports but does not execute code, modify files, delete data, or trigger external operations. It is purely informational/analytical in nature, consistent with other Read-category tools on this server like get_hover_info and get_symbols_overview.
From the tool's definition Tool name 'swift_get_file_imports' and description 'Extract import statements from a Swift file' indicate retrieval of metadata from source code without modification or execution.
Documented attack patterns abuse exactly the kind of access swift_get_file_imports gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SwiftLens, and nothing reaches the server without passing your rules. This is the rule we recommend for swift_get_file_imports:
{
"version": "1",
"default": "deny",
"tools": {
"swift_get_file_imports": {}
}
}swift_get_file_imports 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.
Extract import statements from a Swift file. It is categorised as a Read tool in the SwiftLens MCP Server, which means it retrieves data without modifying state.
Register the SwiftLens MCP server in PolicyLayer and add a rule for swift_get_file_imports: 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 SwiftLens. Nothing to install.
swift_get_file_imports 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 swift_get_file_imports 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 swift_get_file_imports. 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.
swift_get_file_imports is provided by the SwiftLens MCP server (swiftlens/swiftlens). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
