Get started

Four steps to get an agent creating and sending invoices on your behalf, with you approving every send from the dashboard.

1
Create your account
Sign up at billr.cc (or sign in if you already have an account). Sign up in seconds.
2
Set up with your agent
Two ways to get Billr into your agent's hands:
- Install the billr pluginComing soon, launching with the agent release
  In Claude Code:
```
/plugin install billr
```
- Or create an API key manually
  Go to Settings → API in your Billr dashboard and generate a key. Use it with any MCP client or the REST API.
3
Connect
Coming soon, launching with the agent release
Billr exposes an MCP endpoint at https://mcp.billr.cc authenticated with a header:
```
Authorization: Bearer billr_sk_...
```
Claude Code
Add the server with one command, then replace YOUR_API_KEY with the key you created in Settings → API:
```
claude mcp add --transport http billr https://mcp.billr.cc --header "Authorization: Bearer YOUR_API_KEY"
```
claude.ai: add Billr under Settings → Connectors using the same MCP endpoint and API key once the connector is live.
4
Your first invoice
Try a prompt with your agent once it's connected:
```
Create a client called Test Co with my email, draft a $100 invoice for "Setup test", and send it to me.
```
The invoice lands as a draft in your dashboard first. You review and approve the send.
