## Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Microsoft Bookings.
This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Microsoft Bookings account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## Also integrate Microsoft Bookings with

- [ChatGPT](https://composio.dev/toolkits/microsoft_bookings/framework/chatgpt)
- [Claude Cowork](https://composio.dev/toolkits/microsoft_bookings/framework/claude-cowork)
- [Hermes](https://composio.dev/toolkits/microsoft_bookings/framework/hermes-agent)

## TL;DR

### How Atomic Agent connects to Microsoft Bookings
Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.
Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

## Connect Microsoft Bookings to Atomic Agent

### Connect Microsoft Bookings to Atomic Agent
- Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key.
- In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
- Ask Atomic Agent to do something in Microsoft Bookings. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your Microsoft Bookings account, then return to Atomic Agent to continue.
### Headless setup
Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

```bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY
```

## What is the Microsoft Bookings MCP server, and what's possible with it?

The Microsoft Bookings MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Microsoft Bookings account. It provides structured and secure access to booking businesses, appointments, customers, services, staff members, and currencies, so your agent can schedule appointments, manage services and staff, update customer details, and publish or manage booking pages on your behalf.
- Appointment scheduling and updates: Have your agent create appointments for specific services and times, assign staff and customers, update appointment details, or cancel and delete appointments.
- Booking business management: Let the agent create, update, and review booking businesses, then publish or unpublish their external scheduling pages.
- Service and availability setup: Direct your agent to create, update, and list bookable services, including their duration, location, pricing, staff assignments, reminders, and scheduling rules.
- Customer and staff administration: Instruct your agent to add, update, view, list, or remove customers and staff members, including contact details, roles, time zones, and working schedules.
- Booking questions and currencies: Have your agent manage custom intake questions and review the available Microsoft Bookings currency catalog for your scheduling business.

## Troubleshooting

### Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

### Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

### Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection.

## Complete Code

None listed.

## Conclusion

### Use Microsoft Bookings from Atomic Agent
With your account connected, ask Atomic Agent to work with Microsoft Bookings in natural language. You can connect more apps through the same Composio integration as you need them.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Microsoft Bookings MCP?

With a standalone Microsoft Bookings MCP server, the agents and LLMs can only access a fixed set of Microsoft Bookings tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Microsoft Bookings and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Atomic Agent?

Yes, you can. Atomic Agent fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Microsoft Bookings tools.

### Can I manage the permissions and scopes for Microsoft Bookings while using Tool Router?

Yes, absolutely. You can configure which Microsoft Bookings scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Microsoft Bookings data and credentials are handled as safely as possible.
