Connect Copilot

"Copilot" is two products. Microsoft 365 Copilot, the one in Teams and Office, reaches Hiasynth through an agent that whoever looks after your Microsoft tenant sets up once for everybody. GitHub Copilot, the one developers use in VS Code, adds Hiasynth itself in a minute. Both are below.

Microsoft 365 Copilot, through Copilot Studio

There is no "add a server" button in Microsoft 365 Copilot itself. Instead, someone with access to Copilot Studio gives an agent the Hiasynth tools, and publishes that agent to Microsoft 365 Copilot and Teams for everyone else.

Add Hiasynth to an agent

  • In Copilot Studio, open your agent and go to Tools.
  • Select Add a tool, then New tool, then Model Context Protocol.
  • Fill in the three fields. The description matters: the agent reads it to decide when to call Hiasynth.
Field
What to enter
Server name
Hiasynth
Server description
Answers questions about people, places and markets in Europe from a synthetic population: market size, who lives in an area, comparing places, how to reach an audience.
Server URL
https://mcp.hiasynth.co

Choose how it signs in

Pick OAuth 2.0, then Dynamic discovery, and select Create. Hiasynth publishes its sign-in details at the standard locations, so Copilot Studio finds them by itself and there is nothing to type. Each person who uses the agent signs in to their own Hiasynth account the first time.

Connect and publish

On Add tool, select Create a new connection, sign in to Hiasynth and approve, then Add to agent. Publish the agent to Microsoft 365 Copilot or Teams the way you publish any other.

Want one shared account rather than a sign-in per person? Choose API key instead, type Header, header name Authorization, and when creating the connection enter Bearer followed by a key from your connector page. Every question then spends credits from that one account, so the larger credit pack is the one built for this.

Copilot Studio governs MCP servers with the same Power Platform data policies as any other connector, so your admin may need to allow it first.

GitHub Copilot in VS Code

For developers. You need VS Code 1.101 or later, which is when remote servers and sign-in arrived.

Add the server

  • Open the Command Palette and run MCP: Add Server.
  • Choose HTTP, paste the address below, and name it hiasynth.
  • Pick Global to have it everywhere, or Workspace for this project only.
https://mcp.hiasynth.co

Sign in

VS Code starts the server and opens the Hiasynth page in your browser. Sign in with Google, GitHub or Discord (new here? that just made your account), read what is being asked, and approve.

Ask

Open Copilot Chat in agent mode. The Configure Tools button in the chat box lists Hiasynth's tools; make sure they are ticked, then ask:

Compare Munich, Hamburg and Vienna for affluent 30 to 45 year olds.

Prefer the file? It is .vscode/mcp.json in a project, or run MCP: Open User Configuration for the global one. VS Code's top-level key is servers, not mcpServers, which is the one thing that trips people up when copying a config from another client.

{
  "servers": {
    "hiasynth": {
      "type": "http",
      "url": "https://mcp.hiasynth.co"
    }
  }
}

Visual Studio on Windows and the Copilot CLI read a server the same way; only the file location differs.

What next

  • What to ask: questions that show what Hiasynth is good at.
  • Pricing: one subscription, credits that meter what you ask.
  • Troubleshooting: the short list of things that go wrong, and the fix for each.
