"Gmail" matching MCP servers:

Enables sending transactional emails with text or HTML body, delivery status, and message ID via Resend. Pay-per-call using x402 micropayments (USDC on Base L2), no API key or signup required.

Enables billing automation via natural language by creating a Composio MCP server that connects to Gmail, Google Sheets, Xero, and more for invoice generation, expense tracking, and payment processing.

MCP server that lets AI agents create reviewable physical mail drafts, validate quotes, and pay for postage via MPP or x402 protocols.

Your AI agent can't touch Stripe, Gmail, Slack or more, without your tap. mild.run intercepts every sensitive action and sends you a notification to approve or block — before anything executes. Agent never holds credentials.

Enables AI agents to create and manage kankan.email mailboxes, send and receive emails, renew mailboxes, and handle order payments and status queries through MCP tools.

MCP server that gives AI agents read access to subscription/SaaS invoice history, ingested from Gmail and stored in Postgres and MongoDB, with tools for listing invoices, retrieving PDFs, and summarizing spend.
