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.

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 | $0.00087 | $0.01543 |
| Opus 5 | $0.00044 | $0.00772 |
| Sonnet 5 | $0.00017 | $0.00309 |
| Haiku 4.5 | $0.00009 | $0.00154 |
Grade A, and why
mcp-stripe 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 11d 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 — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stripe MCP Transaction Skill
Execute transaction operations via Stripe MCP server.
File-based Pipeline (Pass Paths Only)
When integrating billing operations into multi-step workflows, persist all context and artifacts to disk, passing only paths between agents/sub-agents.
Recommended directory structure (within project): runs/<workflow>/active/<run_id>/
- Input:
01-input/goal.md(requirements),01-input/context.json(known customer/invoice/subscription/payment_intent IDs, etc.) - Plan:
03-plans/stripe-actions.md(list of operations to execute; money/contracts must be written here and await confirmation first) - Output:
05-final/receipt.md+05-final/receipt.json(object type + ID + key fields + next steps) - Logs:
logs/events.jsonl(summary of each tool call; do not log sensitive information verbatim)
Connection Configuration
MCP Server: https://mcp.stripe.com
Claude Code Connection:
claude mcp add --transport http stripe https://mcp.stripe.com/
claude /mcp # authenticate
Authentication: OAuth preferred; if API key needed, use restricted key as Bearer token.
Mode: Test mode by default. Switching to live requires user to explicitly say "live" and double confirmation.
Three Hard Rules
- Read before write - Before creating customer/product/price, first use
list_*orsearch_stripe_resourcesto check if it already exists, avoid duplicate objects - Money and contracts require confirmation -
create_refund,cancel_subscription,update_subscription,update_disputemust display content and get explicit user confirmation before execution - When in doubt, search - If unsure about object ID, fields, or approach, first call
search_stripe_documentationorsearch_stripe_resources, don't guess parameters

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

mcp-stripe is a skill published in the GitHub repository Heyvhuang/ship-faster (339 stars, last pushed 27d ago), licensed MIT. It adds 87 tokens to every session and 1,543 once invoked, about $0.0004 per session on Opus 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.
