ChatGPT

ChatGPT on the web · Plus, Pro, Business, Enterprise and Edu plans

1. Turn on Settings → Security and login → Developer mode. In a Business, Enterprise or Edu workspace, an admin must allow this first. There, you'll find the switch under Settings → Apps → Advanced settings.
2. Open ChatGPT Plugins and select +.
3. Name it Fastweigh, paste the server URL under Connection, choose OAuth if asked, and create it.
4. Sign in to Fastweigh when prompted, then review the tools ChatGPT found.
5. In a new chat, select + and choose Fastweigh. You may find it under Developer mode or More.

Custom apps work on ChatGPT's website, not in the mobile apps. On Plus and Pro, ChatGPT may only let the app read data. Making changes can require a Business or Enterprise workspace. When Fastweigh adds features, open the app from Plugins, select Refresh and start a new chat. For published workspace apps, an admin does this.

Microsoft Copilot

Copilot Studio agents, which can be published to Microsoft 365 Copilot and Teams. An agent maker or IT admin does this setup.

1. Open your agent in Copilot Studio and go to Tools.
2. Select Add a tool → New tool → Model Context Protocol.
3. Enter Fastweigh as the server name and paste the server URL. For the description, try: Looks up Fastweigh tickets, customers, orders and products, and prepares changes for approval.
4. Under authentication, choose OAuth 2.0 → Dynamic discovery. Select Create, then Next.
5. Select Create a new connection, sign in to Fastweigh, then select Add to agent.
6. Try it in the test chat. Generative orchestration must be on for the agent to use Fastweigh.

Share it in Microsoft 365 Copilot and Teams

1. Select Publish, then open Channels → Teams and Microsoft 365 Copilot.
2. Check Make agent available in Microsoft 365 Copilot and select Add channel.
3. Select See agent in Teams to install it for yourself. To share it with everyone, use Availability options. Your admin may need to approve it.

Publishing needs a Copilot Studio license; trials can't publish. The Microsoft Copilot app for personal accounts can't add custom servers.

GitHub Copilot in VS Code

Scripts and other clients

Connect over Streamable HTTP with OAuth discovery and PKCE. For unattended scripts, send a tenant API key as Authorization: Bearer <api-key> and store it as a secret. Changes still need a person to approve them. MCP Inspector is handy for testing.
