# Connect Claude

> Set up the Fyvel MCP server as a custom connector in Claude (claude.ai).

# Connect Claude

This guide is for **Claude on claude.ai** (Settings → Connectors → Add custom connector). For Claude Desktop and other MCP clients, use the same rules as in [Setup & authentication](https://docs.fyvel.io/en/mcp/setup-authentication.md): endpoint `https://www.fyvel.io/mcp` and a bearer token.

> [!NOTE]
>
> Create an [MCP credential in Fyvel](https://docs.fyvel.io/en/mcp/setup-authentication.md#create-an-mcp-credential-in-fyvel) first and copy the token. It is shown only once and starts with `fyv_mcp_`. It is not the API key for Excel or Google Sheets.

## Add the connector

In Claude, open **Settings → Connectors → Add custom connector** and fill in the fields as in the screenshot (red markers 1–4):

![Claude add custom connector dialog with name fyvel, URL, no login, and Authorization header](https://mintcdn.com/fynancegmbh/31XKJWoUtCtFY76r/images/mcp/claude-setup.png?fit=max\&auto=format\&n=31XKJWoUtCtFY76r\&q=85\&s=cd9e5e840077b9f6d93bc693cd977c73)

Custom connector for Fyvel in Claude

| Step | Area | Setting |
| - | - | - |
| **1** | Name and URL | **Name:** `fyvel` (any label you like). **URL:** `https://www.fyvel.io/mcp` |
| **2** | Authentication | **No login** — Fyvel does not use OAuth for MCP; it uses an API token in a header |
| **3** | Request headers | **Header name:** `authorization` (or `Authorization`) |
| **4** | Token | **Value:** `Bearer <your-mcp-token>` — enter exactly, including `Bearer ` and the space. Leave **Required** checked |

> [!WARNING]
>
> Claude may show **Sign in now** as detected when it probes the server, because unauthenticated access is rejected. Ignore OAuth and use **No login** plus the **Authorization** header as above.

Click **Add**. The connector should appear in your connector list.

## First test

1. Start a chat with the **fyvel** connector enabled.
2. Ask Claude to call `list_companies`.
3. Pick the right `companyUuid` for further tools — see [Companies & scoping](https://docs.fyvel.io/en/mcp/companies.md).

## Rotate the token

When you create a new MCP credential in Fyvel, existing MCP tokens for that organisation are revoked. Edit the connector and update the **Authorization** header with the new `Bearer` value.
