KashFlow MCP by usefulapi

KashFlow MCP by usefulapi

Use KashFlow from Claude, Cursor, or any MCP client — work with your invoices, customers, suppliers, banking and accounting reports. Hosted, no local install: connect with your own KashFlow credentials.

Live endpoint: https://kashflow.usefulapi.io/mcp · Homepage: https://usefulapi.io/kashflow

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://kashflow.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http kashflow https://kashflow.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": {
    "kashflow": {
      "url": "https://kashflow.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 KashFlow credentials.

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

On first connect you'll enter your KashFlow username and password (or the separate API password; enable API access under Apps > API Settings). They are validated, stored per-user, and scoped to you — no keys in config files.
