Your AI assistant can now send messages to clients and assist with scheduling instead of just advising you about it. The Apptoto MCP server connects your account to Claude, ChatGPT, Gemini, or Codex, so you can check your calendar, send client messages, book appointments, and update contacts by asking for them in plain language.
What's new
- An MCP serverat https://api.apptoto.com/mcp that any MCP-compatible AI assistant can connect to. Paste the URL into your assistant's connector settings, sign in to Apptoto, and approve the access you want to grant. No code, no API keys to manage, about five minutes start to finish.
- 25+ toolscovering the parts of Apptoto you touch every day: events and calendars, contacts and address books, conversations and replies, booking pages and availability, and appointment auto messages.
- OAuth 2.1 authentication.Your Apptoto password and API keys stay at Apptoto. Your assistant receives a scoped access token instead, and you choose the scopes when you connect.
- Approval on actions.Reading your schedule happens freely. Anything that changes your account, such as sending a message, booking an appointment, or updating a contact, asks you first.
- Step-by-step setup guidesfor each AI assistant: Connect Claude to Apptoto and Connect ChatGPT to Apptoto. New to MCP entirely? Start with What Is MCP? What Appointment-Based Businesses Should Know.
- A free Prompt Packof ready-to-use prompts, and a downloadable Front Desk Skill for Claude that turns your assistant into a daily front-desk helper.
What you can ask for
- "What's on my schedule tomorrow, and who hasn't confirmed yet?"
- "The 2:00 canceled. Who has been asking for a sooner appointment?"
- "Find an opening Thursday afternoon and book Maria Chen in."
- "Which clients haven't been in for 60 days? Draft a win-back message for that list."
- "Mark the 10:00 as a no-show"
- "How did bookings this week compare to last week?"
- "Which appointment types were canceled the most over the last two weeks?"
Why we built it
Most of what fills the first hour of the day is not hard, it is just repetitive: open the calendar, scan for gaps, check who replied overnight, chase the people who did not, note yesterday's no-shows. Whether you run the front desk, the practice, the firm, or the whole crew, that work lands on someone, and it lands again tomorrow. Every one of those steps is a lookup or a small action, and an AI assistant is great at both.
MCP is the open standard that closes that gap. Rather than exporting a CSV and pasting the schedule into a chat window, your assistant communicates with Apptoto directly. Your calendar stays the single system of record, so nothing drifts out of sync.
Where it works
- Claude (web and Claude Code)
- ChatGPT (Plus, Pro, Business, Enterprise, and Edu, with Developer Mode turned on)
- Gemini CLI
- Codex CLI
- Any other client that supports remote MCP servers over HTTP
Is my data safe?
Yes, and you control the boundaries. The connection uses OAuth 2.1 with scoped permissions, so your assistant only sees what you approve. Write actions prompt you individually. The Apptoto side is the same SOC 2- and HIPAA-compliant platform you already use, and messages sent through your assistant are logged in Apptoto exactly like any other message.
One setting worth checking on your end: if you handle PHI or other sensitive client data, turn off model training in your AI assistant's privacy settings before you connect. The setup guides walk you through where to find it in each client.
Try it
Open your assistant's connector or plugin settings, add https://api.apptoto.com/mcp, and sign in to Apptoto. Then ask it something small to start, like "what's on my calendar tomorrow?" Full setup guides for each client are at https://api.apptoto.com/mcp.
