Aura Overview
The Aura MCP server gives autonomous agents a real email address, webhook URL, durable memory, and event-based waiting through a remote HTTP endpoint. Agents claim an identity with a wallet signature, then use MCP tools with USDC payments handled through x402. Reach for it when an agent must receive verification mail, preserve state across runs, or pause without spending tokens on polling. A free identity claim and trial credit allow the service to be evaluated before depositing funds.
Primary Use Cases for Aura:
- Receive verification codes at an agent-controlled email address
- Store memory across otherwise ephemeral agent runs
- Wait for inbound events without polling model turns
- Create webhooks for asynchronous agent workflows
