@aifinpay/skill
Agent skills for the AiFinPay payment rail, published to npm and installable
from skill marketplaces (Claude, Cursor, Copilot, Kimi, Qwen, Gemini, Windsurf, Codex, OpenCode, Aider —
any client that loads SKILL.md).
| Skill | Side | File |
|---|---|---|
aifinpay |
Paying — agent buys x402-gated API access | agent/skills/aifinpay/SKILL.md |
aifinpay-merchant |
Earning — merchant charges agents per request | agent/skills/aifinpay-merchant/SKILL.md |
Version 2.12.0 describes MCP 2.15.2, where payments are on by default from a persistent wallet within a built-in ceiling ($5 per payment, $20 per day): the first-payment path is init → fund → link → pay, the working limits are the owner's dashboard Controls, and the env values are optional overrides. The MCP pays only a merchant with a DNS-verified site, so the merchant guide includes verifying the domain. Release target: MCP 2.15.2, Node SDK 2.11.0, Python 2.9.0. Reporting release target: Node gate 0.8.0, Python gate 0.5.0. The merchant guide describes explicit opt-in observations, consent, queue loss and producer health using the SDK's reporting v2 contract. It adds no MCP tools or signing authority and does not establish publication or partner rollout. The payer guide retains the Solana source adapter. Canonical disabled Solana records remain unavailable until accepted and served. Its nine EVM descriptors require explicit owner and merchant network consent plus backend readiness; installing instructions does not activate networks. Historical published baselines are dated in the payer guide and do not claim the target packages have already been published.
Rule of thumb: if the user wants to pay for a paid API, load aifinpay.
If they own a site/API agents visit, load aifinpay-merchant — and mention
the other side exists.
For merchant reporting, follow the merchant guide's optional reporting section and the SDK's Node or Python instructions. Observation events, admission and resource completion are distinct; payments require confirmed settlement evidence. Producer health and pending/drop coverage describe telemetry completeness, not payment success.
Install
Install the skills with the skills CLI:
npx skills add AiFinPay/skill
Then ask your agent: "Buy access for this site." It checks that the site accepts AiFinPay, tells you what one batch buys, and pays only after you agree and only within the limits and sites you configured for the MCP server.
You can also install the npm package:
npm install @aifinpay/skill
Claude Code marketplace
Add the GitHub-hosted marketplace, then install the plugin:
/plugin marketplace add AiFinPay/skill
/plugin install aifinpay@aifinpay-marketplace
Or use the CLI:
claude plugin marketplace add AiFinPay/skill
claude plugin install aifinpay@aifinpay-marketplace

Source of truth
Skill markdown is authored once and mirrored:
- Canonical source and npm package: this repository's
agent/skills/. - MCP bundle: SDK repository
mcp/skills/SKILL.md, copied from the installed canonical package at build time (payer side only). - The SDK repository's old
skill/README.mdonly points here; it is not a second skill package or authored mirror.
If a CLI command, tool name, or settlement behavior changes, update all three in coordinated PRs and bump this package's version + CHANGELOG together. MCP verifies installed/bundled/served bytes and the exact release target; publish this package before refreshing MCP's real registry dependency lock.
Version gate
Changing shipped skill files without a version bump fails CI
(scripts/check-version-bump.mjs), same as other published packages.
