Stripe AI is a collection of SDKs, tools, an MCP server, and agent skills for building AI products and businesses with Stripe's billing infrastructure. Developers use it to connect Stripe payments and metering to language models and agent frameworks, while the catalogue entries provide Stripe-specific skills, commands, plugins, and agent integrations.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 46 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00084 | $0.01487 |
| Opus 5.5 | $0.00034 | $0.00595 |
| Sonnet 5.5 | $0.00017 | $0.00297 |
| Haiku 4.5 | $0.00008 | $0.00149 |
Grade A, and why
stripe-apps scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 23d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts
The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stripe Apps
Select and read the existing guidance for the user’s task. Product documentation describes what an extension can do; implementation guides describe how to build it. Before recommending an extension or writing code, load the applicable bundled reference files as well as the relevant product documentation. A link or filename in this skill isn’t a substitute for reading its contents.
For a capability question, check native Stripe features and the documented applicability and limitations of the extension. For an implementation request, create or modify working files using the selected guide. For an existing app, inspect its manifest, packages, installed SDK, and local agent instructions before deciding what to change.
Choose the relevant documentation
Use information already supplied by the user or existing app. Read <references/discovery.md> when you need to clarify the app’s requirements, and <references/extension-types.md> for an overview of app architectures. Ask only for missing information that affects the task.
Product capabilities
Use these existing product documents to determine which capability fits and whether the account has the required access. Don’t infer support from an extension’s name or the existence of a scaffold.
| Task | Read |
|---|---|
| Select an extension interface and its supported implementation types | Extension points and how extensions work |
| Change how items are included on subscription invoices | Item handling extensions |
| Customize prorations | Native proration behavior and prorations extensions |
| Apply customer balances | Customer balance extensions |
| Calculate discount amounts | Discount calculation extensions |
| Add an action to Stripe Workflows | Existing workflow actions, existing custom actions, and how custom actions work |
| Customize another product’s behavior | Follow the selected interface’s product documentation from the extension-point catalog |

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

stripe-apps is a skill published in the GitHub repository stripe/ai (2,045 stars, last pushed yesterday), licensed MIT. It adds 84 tokens to every session and 1,487 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
