Sommaire
Lobby — AI Receptionist Toolkit (MCP server)
The official MCP server for Lobby — the bilingual AI front desk. It gives any AI agent eight free, no-auth receptionist tools, served remotely over Streamable HTTP. No key, no signup.
https://lobbyvoices.com/api/mcpThe remote endpoint above needs nothing installed — most MCP clients (Claude Code, Cursor, Claude Desktop) can call it directly over HTTP. This repo also ships lobbyvoices-mcp, a tiny stdio bridge (npx/Docker) for clients that only support local stdio servers.
Connect
Claude Code (remote, no install)

}Stdio-only client — via npx (not published to npm; installs straight from this repo)

}
}Stdio-only client — via Docker
docker build -t lobbyvoices-mcp https://github.com/bodyegypt/lobbyvoices-mcp.git{
"mcpServers": {
"lobbyvoices": { "command": "docker", "args": ["run", "-i", "--rm", "lobbyvoices-mcp"] }
}
}The bridge does no protocol work itself — it's the maintained mcp-remote package pointed at the production endpoint (see index.js).
Tools
| Tool | What it does |
|---|---|
write_phone_script | Writes a business phone script — greeting, voicemail, on-hold, or jingle — in English, Mexican Spanish, or both. Ready to record. |
write_ivr_menu | Builds a complete IVR / phone-menu script: greeting, numbered options, optional press-9 Spanish switch, operator line. |
generate_elevenlabs_agent_prompt | Generates a production-grade system prompt for an ElevenLabs conversational agent acting as a phone receptionist. |
calculate_missed_call_cost | Computes the revenue a business loses to missed calls (monthly + yearly) plus recovery math, break-even days, and ROI. |
simulate_receptionist_call | Role-play a call against the receptionist call engine — you play the caller, get the transcript, outcome, and automatic EN/ES switch back. |
get_demo_call_number | A real phone number anyone can call right now to hear the receptionist live, with suggested bilingual scripts. |
should_i_hire_a_receptionist | Scores a business's phone coverage and returns a verdict — covered, AI front desk, or hybrid — with archetype and leak numbers. |
save_my_receptionist | Saves a phone script, IVR menu, agent prompt, or simulated call built earlier in the conversation and emails it to the person, with the demo number and a signup link. Requires their explicit consent — only fires with consent: true. |
Every tool declares an outputSchema and returns structuredContent, so agents get typed JSON instead of text to parse.
Try it with curl
curl -X POST https://lobbyvoices.com/api/mcp \
-H 'content-type: application/json' \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"calculate_missed_call_cost","arguments":{"callsPerWeek":75,"missedRatePct":33,"avgJobValue":380}}}'Also available as a plain REST API
The same capabilities are exposed as a free, no-key HTTP API — see the developer docs and the OpenAPI spec.
Fair use
No auth required. Per-IP rate limits (AI-backed tools: 2 requests/minute; math and template tools are generous) and hard input caps keep the service healthy. Building something bigger on top? Tell us.
About Lobby
Lobby is an AI front desk for small businesses: it answers every inbound call 24/7, books appointments, captures leads, and speaks English and Mexican Spanish — switching mid-call when the caller does. This MCP server runs on the same production stack.
