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

Terminal

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

Cursor, Windsurf and other HTTP-capable clients

config.json

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

Claude Desktop (via mcp-remote)

config.json

{
  "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

Tool	What it does
`get_account`	Your business details, email-confirmation and payment status
`list_clients` / `create_client` / `update_client`	Find or add the people you invoice
`list_invoices` / `get_invoice`	Filter by status, client or overdue; full detail with line items and a shareable link
`create_invoice` / `update_invoice`	Draft invoices with line items, tax and late fees; totals are computed server-side
`send_invoice`	Emails the PDF to the client, with a Stripe payment link if connected
`mark_invoice_paid`	Record a payment received outside the app
`delete_invoice`	Remove an invoice

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.
