Connect an assistant

Voorcast speaks MCP, so you can connect ChatGPT, Claude or another MCP client to your own data and ask it questions in plain language. Nothing to install. Both ChatGPT and Claude connect by signing in to Voorcast with this URL:

https://api.voorcast.com/api/v1/mcp

Connect ChatGPT

  1. On chatgpt.com, turn on Developer mode in Settings → Apps.
  2. Go to chatgpt.com/plugins, click + and choose Add custom MCP server.
  3. Name it Voorcast, paste the URL above, choose OAuth, accept the warning and click Create.
  4. ChatGPT opens Voorcast: sign in, pick the organisation if you belong to more than one, and click Allow.

Set it up on chatgpt.com in a browser. On Business and Enterprise plans an admin turns on developer mode and adds the app for the workspace; members then connect it.

Connect Claude

  1. In Claude, open Customize → Connectors, click + and choose Add custom connector.
  2. Give it a name such as Voorcast and paste the URL above.
  3. Click Connect. Claude opens Voorcast: sign in, pick the organisation if you belong to more than one, and click Allow.

Then ask ChatGPT or Claude to list Voorcast’s tools. You should see supplier, product, sales, purchase order and reordering tools. The connection shows in Voorcast under Settings → Connected apps, where Disconnect ends its access at once.

On Claude’s Team and Enterprise plans an owner first adds the connector under Organization settings → Connectors; members then connect it under Customize → Connectors.

Claude Code and other clients

These send the key in a header rather than signing in. Create one in Voorcast under Settings → API keys. Leave it read-only unless you have a reason not to. A read-only key can look at your data and cannot change it, and that is enforced by Voorcast rather than by the assistant.

For Claude Code:

claude mcp add --transport http voorcast https://api.voorcast.com/api/v1/mcp --header "Authorization: Bearer YOUR_API_KEY"

Other clients take the endpoint as the server URL and the key as a bearer token:

Authorization: Bearer YOUR_API_KEY

Where you enter those differs per client, so follow its own instructions for adding a remote MCP server.

What it can see

The organisation is the one you picked when you allowed the connector, or the one the key belongs to, so neither can be pointed at anyone else’s account. Disconnect a connector under Settings → Connected apps, or revoke a key under Settings → API keys; both take effect immediately.
