Connect an AI assistant to WATS with MCP

Beta. The WATS MCP server is in beta. Access is granted through the Early Access Program. 

Connect an MCP client such as Claude, ChatGPT or a Copilot Studio agent to WATS, and the assistant can query your test data with your permissions and restrictions.

The MCP server address is shown under My settings > MCP and is your WATS URL plus /mcp:

Two ways to sign in

OAuth (recommended). Paste the MCP URL into the client, log in to WATS in the browser tab that opens, and approve the consent page. WATS OAuth uses Client ID Metadata Document (CIMD). Clients normally select this automatically; if yours asks, choose CIMD.

JWT token. For clients that cannot do OAuth or does not support CIMD. Create a token under My settings > MCP > JWT Tokens and paste it into the client as a bearer header:

Authorization: Bearer <token>

Both ways act as you, with your permissions and restrictions.

Setup guides for tested clients

These are the clients we have tested. Any other MCP client that supports OAuth or a bearer header should work the same way.

Claude

Works in Claude web, desktop and mobile.

1. Open Settings > Connectors > Add custom connector. 

2. Paste the MCP URL and click Add. 

3. Leave the advanced OAuth fields empty. 

4. Click Connect, log in to WATS and approve the consent page. In a chat, click + and enable the WATS connector.

ChatGPT

1. Open Settings > Apps & Connectors > Advanced settings and turn on Developer mode.
2. In Apps & Connectors, click Create. Enter a name, a description and the MCP URL. Choose OAuth as authentication.
3. Save, log in to WATS and approve the consent page.
4. In a chat, click + > More > Developer mode and pick the WATS connector.

Microsoft Copilot Studio

Copilot Studio does not support CIMD, so you must connect with an API key: a JWT token sent as a bearer header.

1. Create a token under My settings > MCP > JWT Tokens and copy it.
2. In your agent, open Tools > Add a tool > New tool > Model Context Protocol.
3. Enter a server name, a description and the MCP URL.
4. Under Authentication, select API key, set Type to Header and the header name to Authorization, then click Create.
5. Choose Create a new connection, enter Bearer <token> as the key, and click Add to agent.
6. Publish the agent and add channels on the Channels page.
