Does Invoice Ninja have an MCP server?
Not an official one yet. A native MCP server has been proposed in Invoice Ninja's main repository and is still in review. Today you can connect Invoice Ninja to Claude through community servers, or use an invoicing app that ships its own 102-tool MCP server.
MCP / AI-agent integration
No official MCP server in a release yet. A native, opt-in server is an open pull request. Several community servers wrap the REST API; you run and maintain them yourself.
First-party, hosted MCP server with 102 tools. Public manifest at /api/mcp/manifest. Works with Claude Desktop, Claude Code, and Cursor with one API key.
Invoice Ninja and MCP: where things stand
Checked November 2026. This changes quickly, so check the links before you decide.
- Native MCP server: in review
A pull request opened in October 2026 adds an opt-in MCP endpoint to Invoice Ninja itself, at
/api/v1/mcp. It has not been merged, so it isn't in a release yet. Follow it on GitHub. - Community servers: available now
Independent developers publish MCP servers that call the Invoice Ninja v5 REST API with your API token. Two of the more complete ones are NightSquawk/invoiceninja-mcp-server (AGPL-3.0, asks before each write) and halviclabs/invoiceninja-mcp (MIT, read-only unless you turn writes on). Neither is made or supported by Invoice Ninja.
- What that means in practice
With a community server you install it locally, keep it updated, and give it an API token with access to your billing data. That works well if you're comfortable running developer tools. If you want Claude to create, send and chase invoices without running a server, use an app with a hosted MCP server.

Prompts you can run in InvoiceCave today

"Who owes me money, and how late is each invoice?"
get_aging_report, summarized by client.
Frequently asked questions
Is there an official Invoice Ninja MCP server?
Not in a release as of November 2026. A native MCP server has been proposed as a pull request in the main Invoice Ninja repository and is still being reviewed.
Can I connect Invoice Ninja to Claude today?
Yes, through a community MCP server. You run it on your own machine with an Invoice Ninja API token. These servers aren't made or supported by Invoice Ninja, so check each one's license and how it handles write access before you give it a token.
Can I move from Invoice Ninja to InvoiceCave?
Yes. Export your clients from Invoice Ninja as CSV, connect Claude with an InvoiceCave API key, and ask it to add each client with the create_customer tool. Then connect your Stripe account to take card payments. The free plan is enough to try it with a few clients first.
The verdict
Invoice Ninja is a strong choice if you want to self-host or need a gateway other than Stripe, and its native MCP server may arrive soon. If you want Claude or Cursor to run your invoicing today, without installing and maintaining a community server, InvoiceCave's hosted 102-tool MCP server is ready on every plan, including Free.
