Which one, for what

Lago B

Good for A team that wants usage metering, plans, wallets and invoicing under its own control and can run PostgreSQL and Redis.

Ahead on

  • Reliability, 86 against 63
  • Maintenance & community, 91 against 82

Watch for

The free edition has one organisation API key with full access. Creating more keys needs a Premium licence and per-resource permissions need an enterprise add-on

Stripe API + MCP A

Good for Sellers already on Stripe who want to charge agents per call over MPP or x402 with fiat settlement, refunds and reporting, and for agents doing account work on Stripe with human approval for risky writes. nevermined suits sellers who want plans, credits and buyer-side caps; tempo is the chain MPP stablecoin payments settle on.

Ahead on

  • Agent ergonomics, 94 against 71
  • Security & auth, 97 against 37
  • Payments & pricing, 65 against 50
  • Transparency & trust, 87 against 59

Also in its favour

  • Agent-ready, a grade of BB or better
  • A hosted endpoint, with nothing to install
  • Runs on your own machine
  • No incidents deducted, where Lago loses 3 points for them

Watch for

Card payments from agents have a 0.50 USD minimum, so per-call micropayments must use stablecoins

Verdicts

Lago

Lago's open-source edition runs usage metering, plans, wallets and invoicing on the owner's servers at no charge, with an OpenAPI 3.1 file of 217 operations and releases about every two weeks. The free edition has one unscoped API key and no audit logs, and Lago's llms.txt understates what its MCP server can change.

Stripe API + MCP

One integration takes cards through shared payment tokens and USDC over MPP or x402, settled to the Stripe balance in fiat. Card payments from agents have a 0.50 USD minimum, so per-call micropayments must use stablecoins.

Before you call either

Lago

  1. Call <your Lago API origin>/api/v1 with Authorization: Bearer <key>. On Lago Cloud the hosts are api.getlago.com and api.eu.getlago.com
  2. Send every usage event with a deterministic transaction_id and an explicit timestamp, and resend the same payload on retry. On the ClickHouse event store a changed timestamp is billed again
  3. Expect 422 value_already_exist for a repeated event on the Postgres event store. Treat it as success for a retry
  4. Page with page and per_page and read meta.next_page and meta.total_count. The default page size is 100 in most cases
  5. Treat the free edition's API key as full access. It can void invoices and terminate subscriptions, so keep it out of prompts and ask a person before financial changes
  6. Before giving an assistant the MCP server, note that it includes delete_invoice, void_invoice, delete_plan and create_payment and sets no read-only annotations

Stripe API + MCP

  1. Switch to an Agent-tagged restricted key or OAuth before 31 October 2026; other keys get a 401
  2. Call stripe_api_search and stripe_api_details before stripe_api_write to get the method and parameters right
  3. When a write needs approval, give the person the URL and retry only after they approve; approvals expire after 24 hours
  4. Send an Idempotency-Key on every create so a retry can't charge twice
  5. On 429, read Stripe-Rate-Limited-Reason and back off with jitter; a 429 without it is a lock timeout
