Discover priced APIs and pay per request (HTTP 402, x402, MPP) in stablecoins through the official hosted Pay MCP server (Streamable HTTP at https://connect.pay.sh/mcp, OAuth sign-in, no keys or local wallet), with the pay workflow skill bundled. Portable Agent Plugins v1 package (mcp.json + skills/), no Python or executables. Disclosure — payments plugin for pay.sh: the curl tool spends the hosted Pay account's stablecoin balance; hosted Pay enforces the account's spending limits (none move until the user sets them) and confirms each payment through MCP elicitation, declined when nobody can answer; the plugin marks its server untrusted, but the documented OAuth setup (`hermes mcp add pay`) replaces that entry with a native one that runs at `trust: full` unless the user sets `mcp_servers.pay.trust: untrusted`; chats sharing a Hermes profile share its Pay account; the tool set is served by the remote MCP server at runtime and is not covered by the pinned sha.

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. Disclosure — 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.
