Get the recording URL for a call by call ID.
AI agents call getCallRecordUrl to retrieve information from Lofty MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data (a recording URL) based on a call ID parameter. It performs a simple query/lookup operation without creating, modifying, deleting, or executing any actions. The blast radius of misuse is minimal—at worst, an unauthorized agent could access URLs for call recordings it shouldn't hear, which is a confidentiality issue but not destructive or operationally damaging.
From the tool's definition Tool name 'getCallRecordUrl' and description 'Get the recording URL for a call by call ID' indicate a retrieval operation with no modification or side effects. The verb 'Get' and the purpose of retrieving a URL confirm read-only access.
