Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

calculate

calculate_missed_call_cost

Computes the revenue a business loses to missed phone calls (monthly and yearly), plus the recovery math: recoverable revenue, suggested answering plan, break-even days, and ROI multiple.

demo

get_demo_call_number

Returns a real phone number anyone can call right now to talk to Lobby's AI receptionist live — plus suggested things to say (English and Spanish) and what to listen for (the mid-call language switch, booking flow).

generate

generate_elevenlabs_agent_prompt

Generates a production-grade system prompt for an ElevenLabs conversational agent acting as a business phone receptionist: identity, job, voice style, booking flow, guardrails, and escalation rules.

ivr

write_ivr_menu

Builds a complete IVR (phone menu / auto-attendant) script for a business: greeting, numbered options, optional Spanish-language switch, and the operator line. English, Spanish, or bilingual.

phone

write_phone_script

Writes a professional phone script for a business — greeting, voicemail message, on-hold message, or jingle lines — in English, Mexican Spanish, or both. Returns ready-to-record text.

save

save_my_receptionist

Saves the phone script, IVR menu, agent prompt, or simulated call you just built for a real business and returns the live demo number plus signup link in this conversation. It does not send email. Offer this only after the human explicitly agrees to save their details, and only call it with consent: true.

should

should_i_hire_a_receptionist

Scores a business's phone coverage and returns a verdict — you're covered, get an AI front desk, or go hybrid — with the caller archetype, yearly leak, suggested plan, break-even days, and ROI.

simulate

simulate_receptionist_call

Role-play a phone call with Lobby's receptionist call engine — the same pipeline behind the product demo: greeting, booking flow, lead capture, and automatic English/Spanish detection (live calls add a full AI brain on top). You play the caller: pass each thing the caller says, get the full transcript and outcome back. Free, text-only, max 6 caller lines.

Is Receptionist Toolkit working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 89 of 91 checks got a reply (97.8%), average response time 208 ms. The bar chart above shows every period we have measured.

How do I connect Receptionist Toolkit?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Receptionist Toolkit need an API key?

No. Receptionist Toolkit completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Receptionist Toolkit?

It answers our handshake in 208 ms on average, which is faster than 71% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
