Get concise help for Swift tools. Pass tool_name for specific help, or None for all tools.
AI agents call get_tool_help 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 fetches informational content (help documentation) about other tools in the SwiftLens server. It has no side effects, makes no modifications to code or system state, and performs no irreversible actions. It is purely a Read operation with minimal security risk.
From the tool's definition Tool description states 'Get concise help for Swift tools' — this retrieves documentation/help text about available tools without modifying code, executing commands, or triggering external operations. It is a lookup/query operation.
Documented attack patterns abuse exactly the kind of access get_tool_help 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 get_tool_help:
{
"version": "1",
"default": "deny",
"tools": {
"get_tool_help": {}
}
}get_tool_help is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get concise help for Swift tools. Pass tool_name for specific help, or None for all tools. 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 get_tool_help: 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.
get_tool_help 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_tool_help 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_tool_help. 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_tool_help 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.
