Claude sees no Sales tools

Area: Claude and MCP · Updated: 11 Nov 2026 · Auf Deutsch · All articles

Symptoms

  • Contacts, lists, call scripts and tasks of the Sales Engine are missing from the tool list of the X3 Growth Intelligence connector.
  • Claude gets „contacts_search gehört zur Sales Engine und ist hier nicht mehr verfügbar.“ with the hint to add the „X3 Sales Engine“ connector.
  • Answers of Sales tools in the X3 Growth Intelligence connector end with the same hint.

Cause

  • The Sales Engine is a product of its own: its tools are served by its own MCP server at https://api.crm.x3growth.io/mcp. X3 Growth Intelligence forwards calls of their old names there only for a transition period.
  • An open chat keeps its tool list: new tools appear in a new chat only.
  • You have no Sales role in this organization (Sales admins give one in the Sales Engine under Einstellungen › Team & Rollen).

How to fix it

1. Add the Sales Engine connector

  • In the dashboard: Claude › Einstellungen › Konnektoren › Benutzerdefinierten Konnektor hinzufügen
  • With Claude (MCP): No MCP tool (a connector is added by the person in Claude; it signs in with X3 Konto like the X3 Growth Intelligence connector)

Name „X3 Sales Engine“, URL https://api.crm.x3growth.io/mcp. The Claude plugin of X3 lists both servers.

2. Check your organizations and roles

auth_whoami of X3 Growth Intelligence lists every organization of the connection with your role and, where you have one, your Sales role (salesRole).

3. Start a new chat

  • In the dashboard: Claude › New chat
  • With Claude (MCP): No MCP tool (an open chat only knows the tools from when it started)

In Claude Desktop always open a new chat afterwards, and switch the X3 Sales Engine connector on in the plus menu.

4. Check your Sales role

  • In the dashboard: Sales Engine › Einstellungen › Team & Rollen
  • With Claude (MCP): No MCP tool (the Sales role is given in the Sales Engine; without it the Sales Engine's connector shows no tools of that organization either)

How to tell it worked

  • contacts_search, sales_lists_list and sales_scripts_list answer in Claude through the X3 Sales Engine connector.
  • The answers carry no hint about the connector any more.

The Sales Engine and X3 Growth Intelligence are separate products, each with its own MCP server and connector in Claude. Both sign in with your X3 Konto. Add „X3 Sales Engine“ with the URL https://api.crm.x3growth.io/mcp next to X3 Growth Intelligence and start a new chat; during a transition period X3 Growth Intelligence still forwards calls of the old Sales tool names and says so in every answer.
