Common questions

Is Invoice2go MCP Server and API by Cotlet safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

How to connect Invoice2go to Claude Code, ChatGPT and any AI agent

Yes, Claude, ChatGPT and other AI agents can work in your Invoice2go account. Invoice2go has no official app in ChatGPT or Claude yet, and its own Claude integration page still says "Request this integration." Cotlet.dev connects your own signed-in Invoice2go account to any AI agent, so you can ask in plain words and the AI creates invoices, sends estimates and follows up on payments for you.

What you can ask

Create an invoice for Mike Torres: 6 hours of electrical work at $85 an hour plus $140 in parts, due in 14 days, and email it to him.

Turn yesterday's estimate for the Patel kitchen remodel into an invoice and send it.

Which invoices are more than 30 days overdue? List the client, amount and due date.

Send a friendly payment reminder to every client with an unpaid invoice from October.

How much was paid to me this month, and how much is still owed in total?

Connect in 2 minutes

Get your API key at https://cotlet.dev/app and export it as COTLET_API_KEY.

Claude Code

claude mcp add --transport http cotlet https://cotlet.dev/mcp/v1 --header "Authorization: Bearer $COTLET_API_KEY"

ChatGPT

Settings → Apps → add connector URL https://cotlet.dev/mcp/v1, then sign in with Cotlet.dev. No API key needed.

Cursor

Copy .cursor/mcp.json from this repo into your project:

"mcpServers": { "cotlet": { "url": "https://cotlet.dev/mcp/v1", "headers": { "Authorization": "Bearer ${COTLET_API_KEY}" } } } }

Run it locally (stdio)

This repo is a real MCP server. It speaks MCP over stdio, lists its Invoice2go tools without any key, and forwards every tool call to the hosted Cotlet.dev server. The hosted URL above stays the recommended way. Use this when your client only starts local servers.

{"mcpServers":{"invoice2go":{"command":"uvx","args":["invoice2go-mcp"],"env":{"COTLET_API_KEY":"your-key"}}}}

Or with Docker:

docker build -t invoice2go-mcp .

docker run -i --rm -e COTLET_API_KEY invoice2go-mcp

Tools: invoice2go_guide, invoice2go_status, invoice2go_open, invoice2go_read, invoice2go_click, invoice2go_type, invoice2go_close. Without COTLET_API_KEY a tool call answers: "Set COTLET_API_KEY. Get a key at https://cotlet.dev/app".

Command line

Python 3.10+, nothing else to install. From PyPI:

pip install invoice2go-mcp        # or run it once: uvx invoice2go-mcp connect

invoice2go-mcp connect

Or straight from this repo:

export COTLET_API_KEY="your-key"

python3 invoice2go_agent.py connect # ready config for Claude Code, Cursor, ChatGPT python3 invoice2go_agent.py status # is Invoice2go ready in your Cotlet.dev account python3 invoice2go_agent.py guide # Invoice2go screens and sign-in link python3 invoice2go_agent.py read # open Invoice2go, read the page, close the browser python3 invoice2go_agent.py tools # list Cotlet.dev tools python3 invoice2go_agent.py serve # start the stdio MCP server (same as no argument)

Questions from Invoice2go users

Does Invoice2go have an API for developers?

Invoice2go publishes no public API or self-serve keys; it lists a REST API only as an integration you can request, and offers a Zapier app. Cotlet.dev works in your own signed-in Invoice2go account instead, so your AI agent can create invoices, send reminders and record payments.

How do I connect Invoice2go to ChatGPT?

Add Cotlet.dev as an app in ChatGPT (Settings → Apps, connector URL https://cotlet.dev/mcp/v1), sign in to Invoice2go once in your Cotlet.dev Cloud Browser, and ask ChatGPT in plain words. No code and no Invoice2go API key.

Is there a way to use Claude with Invoice2go?

Yes. In Claude Code run the one-line claude mcp add command above; in the Claude app add https://cotlet.dev/mcp/v1 as a custom connector. Claude then works in your own Invoice2go account.

Is there an Invoice2go MCP server?

Invoice2go has no official MCP server and no official app in ChatGPT or Claude (checked November 2026). Cotlet.dev is a hosted Invoice2go MCP server that works in your own account, with Claude, ChatGPT, Cursor, Codex, n8n, Make and Zapier.
