## Docs

- [Invx docs](https://invx.app/docs.md): Invx is invoicing for independent contractors and small studios who bill clients abroad. It is also an MCP server: your AI agent can create, find and repeat invoices for you.
- [Connect an AI agent](https://invx.app/docs/mcp.md): Invx is a remote MCP server. Once connected, your agent can issue invoices, look them up, repeat last month's invoice for a client and keep your client list current, using the same rules as the app.
- [Tool reference](https://invx.app/docs/mcp/tools.md): The Invx MCP server exposes 13 tools, always in this order. This page is generated from the same definitions the server publishes in tools/list, so it cannot fall out of date.
- [API keys](https://invx.app/docs/mcp/api-keys.md): An API key lets a command-line tool or an editor reach your Invx account over MCP. Create and revoke keys in Settings → MCP & API.
- [Limits and safety](https://invx.app/docs/mcp/limits.md): How Invx keeps a runaway agent in check, what your agent hears back when a call is refused, and how your data is protected.
