Please install the `fortnox` MCP server into my current AI client (that's you).

Optional prerequisites:
- Fortnox credentials (local mode) — If self-hosting, register at Fortnox Developer Portal, create an app, complete OAuth2 flow for a refresh token (https://developer.fortnox.se)

Canonical MCP server config (stdio transport):
- command: `npx`
- args: ["-y","fortnox-mcp-server"]
- required environment variables:
  - `FORTNOX_CLIENT_ID`: Fortnox app client ID (example: `<your-fortnox-client-id>`)
  - `FORTNOX_CLIENT_SECRET`: Fortnox app client secret (example: `<your-fortnox-client-secret>`)
  - `FORTNOX_REFRESH_TOKEN`: OAuth2 refresh token (auto-persisted after first use) (example: `<your-refresh-token>`)

Note: Two modes: Remote (recommended) uses hosted https://fortnox-mcp.vercel.app/mcp with browser OAuth — no credentials needed. Local mode requires Fortnox app credentials as env vars.

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.
