Your business in a Copilot Studio agent

Copilot Studio agents connect to existing, publicly reachable MCP servers. Microsoft 365 Copilot's own federated connectors read today; writing comes later.

  • A customer's Microsoft Copilot Studio books with you

    Your inbox's public MCP server, at /mcp, lets any assistant see your services and free times, book, ask for a quote, order, and answer what you propose. No sign-in. Each request lands as a booking, quote request, order or message, and your rules answer it.

  • Your own Microsoft Copilot Studio runs your inbox

    The owner MCP server, at /mcp/owner, shows what needs a person, tells an item's whole story, replies to customers, moves items on and edits your services and hours. OAuth 2.1 with dynamic client registration, which your inbox runs itself, or an owner API key in the Authorization header.

Add it in Microsoft Copilot Studio

  1. In Copilot Studio, open your agent, add a tool, and choose an existing Model Context Protocol server.
  2. Give it https://inbox.yourdomain.com/mcp/owner (or /mcp for the customer's side) and its sign-in: OAuth, or an API key header.
  3. Publish the agent to the channels your team uses.

Plans. Copilot Studio. Microsoft 365 Copilot federated connectors are read-only today; Microsoft says writes start rolling out in October 2026.

Checked 30 September 2026 against Microsoft Learn: connect an agent to an existing MCP server. Your inbox speaks every MCP revision from March 2025 to the current one (2026-07-28), so older and newer clients both connect.

Being found

A customer's assistant has to know where you are. Put your inbox's address on your website and in your profiles, and join the Surfing Dog network: a directory assistants search through their own MCP connector, https://network.surfingdog.ai/mcp, which answers with verified businesses near a place or by what they do.

People with no assistant get your page at the same address: book a time, ask for a quote, send a message.

Try it first

Point Microsoft Copilot Studio at the demo bike workshop and ask for a booking: surfingdog.ai/try. When it works, install your own inbox with one line to your AI, and see Connect your AI for every tool the owner server gives it.
