Discover priced APIs and pay per request (HTTP 402, x402, MPP) in stablecoins from a wallet on this machine, through the local `pay mcp` stdio server of the official Pay CLI, with the pay workflow skill bundled. Portable Agent Plugins v1 package (mcp.json + skills/), no Python or executables; the user installs the `pay` CLI (brew or npm) and runs `pay setup` first, and the server is offered only while `pay` is on PATH.

## Good to know before installing

Payments plugin for pay.sh: Hermes starts `pay mcp` as a long-running local process; the curl tool spends the local wallet's stablecoin balance; each payment is confirmed by the user through MCP elicitation (PAY_FORCE_ELICITATION=1, declined when nobody can answer) and the server is marked untrusted; every profile using the plugin shares the same local wallet.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install pay-cli
```

2. Said no? Turn it on later:

```bash
hermes plugins enable pay-cli
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
