Answers to common questions about connecting AI agents to Contentsquare through MCP.

## Why won't the AI agent connect to the MCP server?

Check that you're connecting to `https://api.contentsquare.com/mcp` and that your AI agent supports remote MCP servers. If the agent shows an error, remove the Contentsquare server from its settings and add it again. Also check that you have MCP access under **Account settings** > **Connected apps** > **User access**.

## What should I do if I get an "Access Denied" message or can't authenticate?

Your AI agent should refresh the token automatically. If it doesn't, sign in again from your agent's settings.

## Which AI agents are compatible?

The MCP server works with any MCP-compatible AI agent, including Claude Desktop, ChatGPT (with MCP support), Microsoft Copilot, Gemini Enterprise, and other tools that support the Model Context Protocol standard. Compatibility depends on your AI agent provider implementing MCP support. Check your agent's documentation for its MCP setup instructions.

## Does Contentsquare train third-party models with MCP data?

No. Contentsquare doesn't train any third-party models with data accessed through the MCP server. Contentsquare may review usage patterns and feedback to improve the quality of its services.

## How do I revoke access for an AI agent?

See [Revoke access](https://docs.contentsquare.com/en/mcp/manage-access/#revoke-access).

## Where can I see the Client secret of an application?

You can't view it again. The Client secret is shown only once, immediately after you create the application or rotate its secret. If you lose it, [rotate the secret](https://docs.contentsquare.com/en/mcp/applications/#rotate-a-client-secret) and enter the new secret in the external tool.

## Why did my external tool stop working after a year?

Client secrets are valid for one year. Check the **Status** column in **Connected apps** > **Applications**, then [rotate the secret](https://docs.contentsquare.com/en/mcp/applications/#rotate-a-client-secret) and enter the new value in the external tool.

## Why can't I click Create application?

Only Customer Admins can create and manage applications. Ask a Customer Admin on your account.

## I see an error when creating an application

An account can have up to 100 applications. Delete the ones you no longer use, then try again.
