Analyze Swift files and extract symbol structures (supports single or multiple files).
AI agents call swift_analyze_files 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.
The tool performs static analysis and extraction of semantic information from Swift source files without modifying code, executing operations, or triggering side effects. It aligns with other read-only tools on the server (get_hover_info, get_symbol_definition, get_symbols_overview) that provide code understanding through compiler-grade introspection.
From the tool's definition Tool description states it 'Analyze Swift files and extract symbol structures' with no mention of modification, deletion, or execution capabilities. This is purely a querying/analysis operation on source code.
Documented attack patterns abuse exactly the kind of access swift_analyze_files 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_analyze_files:
{
"version": "1",
"default": "deny",
"tools": {
"swift_analyze_files": {}
}
}swift_analyze_files is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Analyze Swift files and extract symbol structures (supports single or multiple files). 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_analyze_files: 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_analyze_files 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_analyze_files 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_analyze_files. 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_analyze_files 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.
