Microsoft Bookings is Microsoft's shared scheduling service for businesses, appointments, customers, services, and staff. It helps teams manage availability and bookings in one place through Microsoft Graph.

35 Tools

Introduction

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows.

This guide explains the easiest and most robust way to connect your Microsoft Bookings account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

What is Composio Connect?

Composio Connect is a consumer offering that lets anyone plug 1,500+ applications directly into their agent harness — including Hermes. It can:

  • Search and load tools from relevant toolkits on-demand, reducing context usage.
  • Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
  • Manage app authentication end-to-end with zero manual overhead.

Integrating Microsoft Bookings with Hermes

Using Composio Connect CLI

1. Install the Composio CLI

Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

bash
curl -fsSL https://composio.dev/install | bash
Hermes authenticating with Composio

2. Authenticate

Once the CLI is installed, ask Hermes to authenticate with Composio.

3. Connect to Microsoft Bookings

Ask your agent to connect to Microsoft Bookings, or simply request any Microsoft Bookings-related task. Hermes will prompt you to authenticate and authorize access.

4. Done. You're all set with a new Microsoft Bookings connection.

Using Composio Connect MCP

1. Get your MCP URL and API Key

Go to dashboard.composio.dev and copy your Connect MCP URL and API key.

Copy MCP URL and API key from Composio dashboard

2. Open the Hermes config file

bash
nano ~/.hermes/config.yaml

3. Add the Composio Connect MCP server

bash
mcp_servers:
  composio:
    url: "https://connect.composio.dev/mcp"
    headers:
      x-consumer-api-key: "YOUR_COMPOSIO_API_KEY"
    connect_timeout: 60
    timeout: 180

Save with Ctrl + O, Enter, then exit with Ctrl + X.

4. Restart your Hermes agent

Once restarted, ask your agent to connect to Microsoft Bookings or request any Microsoft Bookings-related task. It will prompt you to authenticate and authorize access.

5. Done!

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.

Way Forward

With Microsoft Bookings connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.

From here, you can extend Hermes further:

  • Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
  • Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
  • Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

FAQ

Frequently asked questions

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.

Yes, you can. Hermes 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.

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.

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.
