Beta

AutoUncle Data Services is in beta. The API, MCP tools and agent skill may change often, including breaking changes, until version 1.0. Read the changelog before you upgrade an integration.

Claude Desktop & claude.ai

Add AutoUncle Data Services to Claude as a custom connector. A connector added on claude.ai is also available in Claude Desktop for the same account.

Prerequisites

  • A Claude plan that allows custom connectors. Free plans can add one.
  • A verified AutoUncle account that is a member of the workspace you want to use.
  • On Team and Enterprise plans, an organization Owner adds the connector first.

Pro, Max and Free plans:

  1. Open Customize → Connectors and choose Add custom connector.
  2. Enter the URL https://data-services.autouncle.com/mcp.
  3. For authentication, choose to sign in. For the OAuth client, choose Register automatically. AutoUncle supports dynamic client registration; it does not publish a client ID metadata document, so "Claude's published identity" falls back to the same automatic registration.
  4. Sign in with your AutoUncle account, choose the organization and approve the scopes.

Team and Enterprise plans: an Owner adds the connector under Organization settings → Connectors → Add → Custom → Web with the same URL. Each member then chooses Connect and signs in as themselves.

OAuth valuations are live and use the chosen organization's credits. Claude requests the scope the server advertises in its 401 response; approve only the scopes you want the connector to have.

Authentication settings cannot be edited after the connector is created. To change them, remove the connector and add it again.

Connect with an API key (limited beta)

Claude offers request headers for connectors as a beta for a limited set of organizations. If your organization has it:

  1. Add the custom connector with the URL above and choose No sign-in.
  2. Under Request headers, add a header named authorization with the value Bearer au_test_.... Claude adds no prefix, so include Bearer.

You cannot set an Authorization header on a connector that also uses OAuth. If request headers are not available to you, use OAuth, or use Claude Code, which supports API key headers.

Claude Desktop configuration file

Claude's documentation routes remote servers through Connectors and describes claude_desktop_config.json as the mechanism for local servers. If you must use the file, run a local bridge such as mcp-remote; see other MCP clients.

Verify the connection

Start a new chat, make sure the connector is enabled for it, and ask:

Use AutoUncle Data Services to call get_account. Which organization is connected, what is the key mode, and how many credits are left?

Then ask for a valuation and check that Claude reports the price basis, currency, interval and precision grade.

Troubleshooting

Symptom Fix
Sign-in loops or fails Make sure your AutoUncle email is verified and that you are a member of the organization you choose.
"Wrong resource" or token rejected The URL must be exactly https://data-services.autouncle.com/mcp. Remove and re-add the connector.
Valuations use credits OAuth is always live. Use an API key header with a test key (if available to you) or Claude Code to test for free.
insufficient_scope Reconnect and approve the missing scope.
