F-sąskaita MCP by usefulapi

Use your F-sąskaita account from Claude, Cursor, or any MCP client. Read invoices, expenses and their PDFs, and create invoices and record expenses. Hosted, no local install: connect with your own credentials.

Live endpoint: https://f-saskaita.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://f-saskaita.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http f-saskaita https://f-saskaita.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "f-saskaita": {
      "url": "https://f-saskaita.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your F-sąskaita credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/f-saskaita/

On first connect you provide a business API token (F-sąskaita → Settings → Integrations → API). The server validates it and stores it per user. No keys go in config files.
