Lago integration

Lago is an open-source usage-based billing platform, self-hosted or run on Lago's own US and EU clusters. Create and read customers, subscriptions and plans with their charges, charge filters, fixed charges, entitlements and metadata; ingest usage events one at a time or in batches and estimate the fees they would produce; define billable metrics and evaluate their expressions; issue, finalize, void, refresh, retry, preview and download invoices, credit notes, payments, payment requests and payment receipts; manage coupons and applied coupons, add-ons, taxes, features and privileges, wallets, wallet transactions with their consumptions and fundings, and wallet or subscription alerts; read current, past, projected and lifetime usage per customer or subscription; pull gross revenue, MRR, invoiced usage, invoice collection, overdue balance and usage analytics; and manage billing entities, the organization, webhook endpoints and the webhook signing public key, plus activity and API logs. The host is part of the credential: use your own domain when self-hosting, api.getlago.com for the US cluster or api.eu.getlago.com for the EU cluster. Authentication is a Lago API key, created under Developers, API keys, sent as a bearer token.

What you can do with Lago

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Use Lago from Claude Code, Cursor or Codex

Connect Lago in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Lago operations become tools the client can call, next to every other integration you connected.

Set up the MCP server step by step

How to connect Lago

  1. Create your workspace

    Sign up free. Nothing to install.

  2. Connect Lago once

    Add your Lago connection in Settings. Every tool from this integration reuses it, and secrets are encrypted at rest and visible only to you.

  3. Describe the job in chat

    The workflow builds itself in front of you and picks the endpoints it needs. Drag the steps yourself on the canvas whenever you would rather be explicit.
