Access 5+ ATXP agent tools via MCP: web search, AI image generation, email, and music generation. Free tier with pay-per-use Pro tier via x402 micropayments (USDC on Base mainnet).

Enables MCP-compatible AI agents to create Gmail drafts, send Gmail email, and append text to Google Docs while keeping OAuth tokens inside the server.

Provides full access to Microsoft Outlook calendar and email through Claude Code by intercepting browser tokens from an existing signed-in Edge profile, eliminating the need for Azure app registration.

MCP server for corporate Exchange that provides access to email, calendar, and people directory via OWA JSON API.

Sendmux is an email inbox API and email API for AI agents. Use this MCP server to let authorised agents work with Sendmux mailboxes, inbound email, clean JSON parsing, webhooks, outbound sending, provider routing, logs, billing, and team controls.

Self-hosted email for AI agents: unlimited mailboxes on your own domain with docker compose, OTP/link extraction, mail_wait_for, web dashboard. v0.7.3: webhook wake example, reliable long waits (mail_wait_for), optional pending journal for task claims. Release: https://github.com/openagentemail/openagentemail/releases/tag/v0.7.3

An MCP server that exposes a mock email verification tool over stdio transport, providing structured JSON results with statuses valid, invalid, or risky.

Enables AI coding agents and LLMs to scrape web pages into clean Markdown, audit email deliverability and authentication records, and verify email signup fraud risk through MCP tools.

Enables interaction with Microsoft Outlook services (Tasks, Calendar, Email, Contacts, and Teams) via the Microsoft Graph API, providing 39 tools for Claude Desktop with natural language and JSON output.

Enables agentic administration of Infomaniak accounts via Claude, offering 169 tools for web hosting, mail, domains, DNS, and more, with a strict two-phase commit for safe mutations.

Full-stack email MCP server in Rust: IMAP, SMTP, Exchange Web Services, and Microsoft Graph in one binary, with OAuth2 and multi-account support. Read, search, send, reply, forward, bulk operations, and attachment download to disk.

A unified MCP server that lets AI agents (Claude Code, Codex, Cursor) deploy web apps and VPS instances, provision Supabase-compatible Postgres/Auth/Storage databases, register DNS domains, and send transactional email using a shared MONA Pass identity and VND wallet. It also embeds MONA Pay tooling for VietQR top-ups, checkout, webhooks and reconciliation, so agents can handle payment requests, budget approvals and resource lifecycles end to end.
