Receptionist Toolkit

com.lobbyvoices/receptionist-toolkit

Lobby's receptionist toolkit is a no-auth HTTP API wrapped in an MCP server that gives your agent seven tools for building phone systems. You get phone script generation in English and Mexican Spanish (greetings, voicemails, IVR menus), ElevenLabs agent prompt creation with booking flows and guardrails, and missed-call cost calculators that output monthly revenue leak and break-even math. There's also a call simulator that role-plays against Lobby's production engine and returns transcripts. Rate-limited to 2 requests per minute on the AI endpoints but otherwise free and immediate. Reach for this when prototyping voice workflows or building receptionist tooling without spinning up your own prompt library.
