stripe/link-cli is a command-line tool that lets agents obtain temporary payment credentials from a Link wallet for approved purchases without exposing the user's real card details. It is used by agents to complete web checkouts or programmatic payments while requiring purchase approval. The catalogue entries provide components for integrating the CLI with agents.
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 | $0.00063 | $0.00626 |
| Opus 5.5 | $0.00025 | $0.00250 |
| Sonnet 5.5 | $0.00013 | $0.00125 |
| Haiku 4.5 | $0.00006 | $0.00063 |
Grade A, and why
check-link-wallet 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 2mo 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 — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Check a Link wallet
Read-only inspection of the connected Link account through the Link MCP server. Nothing here moves money or changes a spend request.
To actually buy something, use the complete-link-purchase skill instead.
Tools
| Question | Tool |
|---|---|
| Which account is connected? | get_userinfo |
| What cards and bank accounts are saved? | list_payment_methods |
| What shipping addresses are saved? | list_shipping_addresses |
| What purchases are pending or approved? | list_spend_requests |
| What is the status of one purchase? | get_spend_request |
Call only the tool that answers the question. Do not sweep all five to build a picture the user did not ask for.
Spend request status
list_spend_requests returns only active requests by default — those in
created, pending_approval, or approved. Pass includeHistory when the
user is asking about something that already finished or expired.
The statuses mean:
created— exists, but the user has not been asked to approve it yet.pending_approval— waiting on the user. They approve in the Link app.approved— ready to spend against.- Expired and terminal states are only visible with
includeHistory, and cannot be spent against. A user who still wants the purchase needs a fresh one, raised withrequest_virtual_card— but only if they ask for it. Do not offer to re-run a purchase off the back of a status question.
get_spend_request returns the status of a single request by id. Do not pass
the include parameter here. include: ["card"] and
include: ["shared_payment_token"] return live payment credentials, and they
belong only in the moment of paying, which is the other skill's job.
What to expose
- Summarize. Do not dump raw JSON or object ids unless the user asks.
- Payment methods: brand, type, and last four only. Never a full number.
- Shipping addresses: city and postcode by default. Give the full address only if the user asks for it.
- Never surface tokens, credentials, or internal identifiers as an aside.
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.

check-link-wallet is a skill published in the GitHub repository stripe/link-cli (882 stars, last pushed today), licensed MIT. It adds 63 tokens to every session and 626 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.
