callbay: your AI agent makes phone calls for you

your coding agent (claude code, codex, claude desktop, chatgpt) gets one new tool: make a phone call. it calls the restaurant, the doctor's office, the airline, the hotel, sounds like a normal person, gets it done, and tells your agent what happened.

how it works

load credits (from $10.00, reloads monthly unless you untick it). calls cost $0.25/min of talk time, held up front and settled when the call ends.
you get a key and one prompt. paste the prompt into your agent. it installs callbay itself.
ask for things like normal. "book me a table for 4 at nopa tomorrow around 7."

add credits

top up anytime from my account or ask your agent (callbay_add_funds).

what it's good at

dinner reservations, including "anything between 6:30 and 8"
doctor, dentist, vet, and salon appointments
asking a dealership about a car, price, or service slot
home internet: new service, outages and credits, lowering the bill, moving, cancelling
flight rebooking after a cancellation or delay, date changes, refunds
store hours, stock checks, quotes, "do you do X"
sitting through phone menus and hold music

how it sounds

short, casual turns. no "certainly!", no support-bot voice.
no recap at the end. it says "perfect, thanks!" and hangs up. your agent gets the recap.
asks your agent mid-call when the business needs something it wasn't given.
it doesn't announce itself. if someone sincerely asks whether it's an AI, it says yes and carries on. see rules.

the prompt

this is what you paste into your agent after paying (your key goes where the placeholder is).

Set up callbay so you can make phone calls for me (book restaurants, doctor's appointments, call businesses for info).

1. Add the callbay MCP server and sign me in. Use whichever matches you:
   - Claude Code:  claude mcp add --scope user --transport http callbay https://call4.me/mcp  (then I run /mcp, pick callbay, and choose authenticate)
   - Codex:        codex mcp add callbay --url https://call4.me/mcp  then  codex mcp login callbay
   - Claude Desktop, claude.ai, or ChatGPT: I'll add a custom connector with the URL https://call4.me/mcp and sign in when it asks.
   I sign in with Google or X. If I have no credits yet, I load some at https://call4.me (from $10).

2. Restart or reload MCP servers if needed, then call callbay_get_balance to check it works.

3. Set up my calling profile now, so calls never stall on missing details: call callbay_get_profile, then ask me in ONE message for whatever is missing (full legal name as on my ID, date of birth, phone, email, home address, health insurance carrier + member ID + group number or self-pay, dental insurance, my car's year/make/model/mileage/VIN if I have one, frequent flyer numbers and status, and TSA PreCheck/Global Entry Known Traveler Number). Never ask for or save my Social Security number, card numbers, or passwords. Save my answers with callbay_save_profile. Skip anything I decline.

4. From now on, when I ask you to call somewhere:
   - Pick the category and call callbay_get_requirements. Ask me for every required detail you don't already have in one message before dialing (reason for the visit, new or existing patient, which days/times work, party size...). The caller can only say what you give it.
   - Find the number (web search if needed) and make sure it's the right location.
   - Place the call with callbay_place_call, then keep calling callbay_get_call until it finishes. If the caller asks a question mid-call, answer it quickly with callbay_answer_question; the business is waiting on the line.
   - Tell me the result in one or two lines.
