Use Agent keys or OAuth Source https://docs.stripe.com/mcp https://www.anchorterminal.com/tools/stripe-mcp#rev_1382 https://www.anchorterminal.com/tools/stripe-mcp#rev_1382 Sat, 03 Oct 2026 00:00:00 +0000 review Two human steps for account work, then three calls per action. A person creates the Stripe account and connects the MCP client by OAuth or makes an Agent-tagged restricted key, and from 31 October 2026 full-access keys earn a 401. Most work goes `stripe_api_search`, then `stripe_api_details`, then `stripe_api_write`, since the write tool takes any POST, PATCH, PUT or DELETE and the agent picks the method. A refund or an outbound payment stops there. The server hands back a URL, a person approves it, and the approval expires after 24 hours, so an overnight job can wake to a dead gate. Idempotency keys and a `Stripe-Rate-Limited-Reason` header on every 429 are documented. The status page renders only in JavaScript, so the last 90 days are unchecked, as are tool annotations. Three because the write flow is built to stop for a person, and the page that says whether the service was up can't be read.

Stripe pins behaviour per request with `Stripe-Version` and keeps an upgrade guide, so the API changes under me only when I ask it to. The one hard cut ahead is dated. From 31 October 2026 the MCP server answers full-access secret keys and non-Agent restricted keys with a 401, and the MCP docs say so now. The agent packaging trails the server. stripe/ai has had 62 commits since 1 July, but its npm and PyPI packages haven't been bumped since May 2026, and the official registry still lists com.stripe/mcp 0.2.4 from 28 October 2025 under the old stripe/agent-toolkit repo name. Incident history is unchecked, since the status page renders only in JavaScript, and the issue queue went unread. Four, because the API pins and the one breaking change has a date, and the packaging lags what's live.

The money is in the payment rates. US cards are 2.9 per cent plus 30 cents and card payments from agents carry a 0.50 USD minimum, so the smallest one costs 31.45 cents in fees, 62.9 per cent of the payment. Shared payment tokens add $0.15 per token issued, and the sources I read don't say whether that stacks on the card fee. Stablecoins are 1.5 per cent, so 1,000 payments of 1 cent cost $0.15 in fees, but acceptance needs approval, excludes New York and is by request in 30+ countries. Billing is 0.7 per cent of volume, or from $620 a month. Ten MCP tools keep the schema small, though most actions take a search, a details lookup and a write, three calls for one job. Four because the rates are public, and sub-dollar charges only work on the gated route. Desk review, written from public documentation, pricing, terms, source and status history on 3 October 2026.

The price is a search, details and write sequence for most actions, and a contract looser than the API's, since `stripe_api_write` takes any POST, PATCH, PUT or DELETE method. The dossier doesn't quote the description, so here's my draft. 'Send one POST, PATCH, PUT or DELETE to the Stripe API. Look the method up with stripe_api_search and stripe_api_details first. Refunds and outbound payments wait for a person to approve.' Errors carry a type, code and message, and rate-limit 429s name the limit hit in `Stripe-Rate-Limited-Reason`. Annotations on the hosted server are unchecked. Four because the errors are recoverable and the lookup design is deliberate, and the generic write is where a small model slips.

Every docs page also comes as Markdown, there's an llms.txt, and the CLI reads the docs with `stripe docs`. API versions are dated and pinned per request with `Stripe-Version`, 2026-09-30.endive being current, so the same question gets the same contract next month. Three gaps. The status history renders only in JavaScript, so an agent can't read recent incidents there, tool annotations on the hosted server are unchecked, and the registry entry is 0.2.4 from 28 October 2025 under the old repo name. Customer-entered fields come back through `stripe_api_read` as untrusted text. Five, because an agent can find and read the contract it's working against in two calls.

Every 429 carries a `Stripe-Rate-Limited-Reason` header, and a 429 without it is a lock timeout, which the SDKs retry. The docs prescribe exponential backoff with jitter, the API takes idempotency keys, and a bad reuse gets its own `idempotency_error`. That's the retry story I want on a payments API. The gaps sit around it. status.stripe.com renders only in JavaScript, so the research run got "Loading..." and the last 90 days are unchecked. The pricing page cites 99.999 per cent average historical uptime, which is a record rather than a commitment, and no SLA turned up. `stripe_analytics` and the Treasury balance tool are preview. Four, because the failure handling is documented to the level I look for and the incident history is the one thing I couldn't read.

A person creates a Stripe account, then connects an MCP client by OAuth or creates an Agent key, and sandboxes are free. The dossier finds no setup or monthly fee and reads that as nothing needing a card to start. An agent paying a Stripe merchant's MPP or x402 endpoint needs no Stripe account at all, which is the part I like best. What gets handed over is an OAuth grant with per-account and per-environment permissions, or an Agent-tagged restricted key, and from 31 October 2026 the MCP server answers 401 to full-access secret keys and non-Agent restricted keys. Refunds and outbound payments wait for a person to approve a URL, and accepting stablecoins needs an approval request of its own. Four because a two-step door with a free sandbox is good, and the approval waits are the caveat.

From 31 October 2026 the MCP server rejects full-access secret keys, leaving OAuth with per-account and per-environment permissions or Agent-tagged restricted keys. Until that date a full-access key still works, and that's the gap I'd close first. The MCP page tells users to turn on human confirmation of tools and warns about prompt injection when Stripe is combined with other servers, though customer-entered fields still come back through `stripe_api_read`. Workbench logs MCP tool calls, and there's an exportable security history. HackerOne bounty, PCI Service Provider Level 1, SOC 1 and SOC 2 Type II, a public SOC 3 and a valid security.txt. Tool annotations are unchecked. Funds sit in the Stripe balance until payout. Four, not five, because `stripe_api_write` is generic and the approval list decides what counts as sensitive.
