InvoiceBloom MCP server

Create, send and track invoices from Claude, Cursor, or any Model Context Protocol client.

InvoiceBloom is a free invoicing app for freelancers and small businesses. Its MCP server is hosted: there is nothing to install or run. Point your client at the endpoint with an API token and start invoicing.

• Endpoint: https://invoicebloom.io/mcp (Streamable HTTP, stateless)
• Auth: bearer API token, minted at Settings › Security (free account)
• Docs: https://invoicebloom.io/developers
• REST API: https://invoicebloom.io/api/v1 with the same token

Quick start

Claude Code

claude mcp add --transport http invoicebloom https://invoicebloom.io/mcp \
  --header "Authorization: Bearer ib_YOUR_TOKEN"

Cursor, Windsurf and other HTTP-capable clients

{
  "mcpServers": {
    "invoicebloom": {
      "url": "https://invoicebloom.io/mcp",
      "headers": { "Authorization": "Bearer ib_YOUR_TOKEN" }
    }
  }
}

Claude Desktop (via mcp-remote)

{
  "mcpServers": {
    "invoicebloom": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://invoicebloom.io/mcp",
               "--header", "Authorization: Bearer ib_YOUR_TOKEN"]
    }
  }
}

Then ask things like "Invoice Acme for 12 hours of consulting at $150 and send it" or "Which invoices are overdue?".

Tools

send_invoice and delete_invoice carry MCP annotations (openWorldHint, destructiveHint) so well-behaved assistants confirm with you before calling them.

Safety and limits

• A token has the same rights as your account. Revoke it from Settings › Security the moment you think it leaked.
• 120 requests per minute per token.
• The same anti-abuse rules as the web app apply to sending: a confirmed email, at least one line item, and a daily send cap.
• Unauthenticated requests get a JSON 401.

Registry metadata

server.json follows the official MCP Registry schema for remote servers.
