+description: Privacy-first agent email inboxes and workspace automation through hosted Mermail MCP. Portable
+  Agent Plugins v1 package (mcp.json + skills/, seventeen skills bundled); authenticate with OAuth via
+  `hermes mcp login mermail`. No credentials are stored in mcp.json. Disclosure — the bundled skills also
+  expose Mermail's paybox wallet tools over the hosted MCP (x402 payments, xStocks trading, standing grants);
+  the skills allow the agent to move funds without a same-turn confirmation when your message already
+  states exact terms, so spending controls live on your Mermail account, not in Hermes.
