mails-agent
mails-agent is an open-source email API for AI agents. It is built for agent workflows that need inbox access, verification-code extraction, search, replies, and MCP tools, and it can run with self-hosted Cloudflare control.
Its API covers sending and receiving email, including CC and BCC, In-Reply-To threading, and attachments. Messages received through Cloudflare Email Routing are persisted to R2 before parsing or routing, and the service offers full-text search across an inbox. It also extracts verification codes automatically for English, Chinese, Japanese, and Korean, and can long-poll until a code arrives. Other supported functions include webhooks with HMAC-SHA256 signature verification, SSE streams for message.received events, auto-labeling for newsletter, notification, code, and personal mail, and deterministic extraction of orders, shipping details, calendar events, and receipts. A built-in console lets users inspect mailboxes, messages, and webhook deliveries.
The product is offered through a CLI, Python SDK, MCP server, and agent-native skill packs. The page shows command-line installation with npm, Python usage through mails_agent, and MCP configuration for tools such as Claude Desktop, Cursor, and Windsurf. It also mentions custom domains and walks through SPF, DKIM, and MX verification for deliverability on a user’s own Cloudflare account. The service is presented as open source and MIT licensed, with self-hosting on Cloudflare and a free self-hosted tier tied to Cloudflare’s free plan limits, while hosted alternatives use usage-based pricing.
