A headless, disposable email inbox that an AI agent drives over MCP, enabling temporary email addresses and email receipt for testing signup flows.

An autonomous MCP agent that helps you apply to fully funded MS and PhD programs by discovering professors, verifying faculty status, matching projects, and drafting cold emails.

Enables AI agents to read and send email, handle attachments and manage calendar invitations through their own IMAP/SMTP mailboxes, with per-mailbox sender and recipient allow lists and automatic HTML-to-Markdown conversion. It runs as a single self-hosted Docker container, exposing the same tools over MCP and REST.

Agent-native cold-email infrastructure providing ~12 high-level tools for domain setup, mailbox provisioning, campaign launch, inbox management, and metrics, all operated via MCP or CLI.

MCP server for Yahoo Mail over IMAP+SMTP that enables AI assistants to manage emails fully—listing, reading, searching, threading, flagging, moving, archiving, handling attachments, and sending/reply/forward/draft—using an app-specific password.

Enables AI agents to read, send, and reply to GPG-encrypted email over IMAP/SMTP, manage a contact book with key provenance, and archive and search everything read. Key material and message bodies are kept out of the model's context window, with encryption enforced by default.

Enables AI agents to access 13 paid micro-tools over x402, paying per request in USDC on Base without API keys or signup. It covers email deliverability, grading, and templates, plus utilities like crypto prices, domain age, hashing, JSON conversion, JWT decoding, regex, slugs, UUIDs, and weather.

Provides temporary email inboxes for AI agents, enabling creation, inspection, and deletion of inboxes, retrieval of messages, and extraction of OTPs and verification links via MCP tools.

Provides context-aware cold outreach guidance for AI clients via a single tool, cold_email_guidance, helping draft personalized and effective emails.

Enables AI agents to manage email over JMAP, including inspecting mailboxes, searching and retrieving messages, navigating threads, downloading attachments, triaging inboxes, and sending emails atomically via HTTP.
