Works with your agents

  • Claude Code
  • claude.ai
  • Codex
  • Any MCP client

From session to sent invoice

Three steps, then billing happens inside the sessions you are already running.

  1. Install

    Add the Billr MCP server to your agent config. One entry, no SDK.

  2. Connect

    Paste a scoped API key from your settings. Revoke it whenever you want.

  3. Bill

    Ask for an invoice in plain language. It shows up in your dashboard.

Nothing happens off the books

Agents draft by default. Every action lands in your dashboard, and you decide what goes out to a client.

You see everything

Drafts, sends, payments, and logged hours all show up in the same place, whoever created them.
