Stripe — can an agent use it?
The reference implementation for agent commerce: Stripe co-authors both ACP and MPP, runs an official MCP server at mcp.stripe.com, and issues merchant- and amount-scoped payment credentials. The main friction is a read-request allocation that penalises poll-heavy agents.
Can an agent get correct information?
Machine-readable surface — 9.5/10
docs.stripe.com publishes /llms.txt with an explicit instructions block, a .md plain-text variant of every docs URL, and a machine-readable skills index at /.well-known/skills/index.json. source
Information retrieval quality — 9/10
Concrete, current numbers are public — 2.9% + 30c domestic cards, Billing from $620/mo or 0.7% of volume, Radar $0.02/screened transaction, Issuing $0.10 virtual / $3.50 physical — though the Agentic Commerce Suite still routes through a waitlist rather than published terms. source
Documentation for machines — 10/10
Industry benchmark: per-field API reference with runnable examples in 8 languages, a dated developer changelog per release train (Acacia/Basil/Clover), and a documented error-code taxonomy. source
Can an agent do the job?
Action coverage — 10/10
The API is the product — every dashboard action has an endpoint, and sandbox mode mirrors live behaviour including webhooks and disputes. source
Agent protocol support — 10/10
Official remote MCP server at mcp.stripe.com with OAuth or restricted-key auth and revocable sessions, plus installable Agent Skills discoverable at docs.stripe.com/.well-known/skills/index.json. source
Access & auth friction — 9.5/10
Self-serve keys in minutes with per-resource none/read/write restricted keys (rk_live_/rk_test_) that Stripe explicitly tells you to use when handing a key to an AI agent; live money movement still requires account activation and KYC. source
Agent payment capability — 10/10
Defines the category: co-author of ACP (Apache-2.0, spec version 2026-04-17, with OpenAI) and of MPP (launched 18/03/2026 with Tempo, HTTP 402 with WWW-Authenticate: Payment, GA on PaymentIntents), plus Shared Payment Tokens scoped by merchant, amount and currency and Issuing for agents behind Link's agent wallet. source
Cost & rate fairness — 8.5/10
No charge for API access and no agent-vs-human price discrimination, but reads are allocated at 500 GET requests per transaction on a 30-day rolling average (floor 10,000/month) and rate-limit increases above 100 req/s live / 25 req/s sandbox require contacting support rather than a self-serve tier. source
Will it still work next quarter?
Permission & ToS stance — 9/10
Programmatic use is the intended use and agents are explicitly catered for at docs.stripe.com/agents; the Services Agreement's restrictions (no circumventing technical limits, no reverse engineering, suspension if activity raises fraud rates) are compliance-driven rather than anti-automation. source
Reliability & continuity — 9/10
Date-versioned release trains with published per-train changelogs, a 72-hour rollback window after upgrading, and a public per-service status page; incidents in H1 2026 clustered on regional payment methods (SEPA Instant, BLIK, Swish, MobilePay) rather than the core API, and I could not verify a documented RSS/JSON status feed for programmatic consumers. source

Point-in-time assessment — services change terms, prices and APIs often. That volatility is itself scored under Reliability & continuity. Re-verified at least quarterly.
