# Commercial MCP Clients

Generic Configuration Guide for any client which supports connections through the MCP Protocol

An MCP client is any application capable of connecting to a remote MCP server on your behalf. This includes conversational AI assistants such as ChatGPT and Claude, as well as development environments such as Cursor and Visual Studio Code.

### The setup pattern

Although configuration screens and terminology vary between clients, the connection process follows three common steps:

1. **Add the remote MCP server:** Depending on the client, this option may be described as a custom connector, remote server, or HTTP server. Do not select a local or `stdio` server configuration, as Nichefire does not provide a local server binary.
2. **Enter the endpoint URL:** Use the Nichefire MCP endpoint assigned to your environment, including the `/mcp` path. See [**Environments & Access**](/overview/environments-and-access.md) for details.
3. **Authenticate the connection**: Sign in through your browser using OAuth 2.1 or provide an API key through the `x-api-key` request header. See [**Authentication**](/quick-start/authentication.md) for instructions for both methods.

### Verifying the Connection

After a successful connection, the client displays the Nichefire tools available to your organization. Reviewing this list is the quickest way to verify both the connection and your organization’s access.

* **Nichefire tools are listed:** The connection is working. The displayed tools represent the capabilities available to your organization.
* **The connector is present but no tools are listed:** Authentication succeeded, but no capability families may be enabled. Contact your Nichefire representative.
* **The connector cannot be added:** Verify the endpoint URL and authentication credentials. Refer to the troubleshooting section on the [**OAuth 2.1 Authentication**](/quick-start/authentication/authentication-through-oauth-2.1.md) or[ **API Key Authentication** page](/quick-start/authentication/authentication-through-api-key.md).

Once connected, you can submit requests in natural language, such as:

> What trends are emerging in specialty coffee?

The client determines which Nichefire tool to use and incorporates the result into its response.
