KeyID – Free email and phone infrastructure for AI agents (MCP)

In plain words

KeyID provides email and phone infrastructure designed specifically for AI agents through the Model Context Protocol (MCP). It enables AI systems to send and receive emails and make phone calls as part of their operations. The service is free to use. KeyID is built for developers and organizations deploying AI agents that require communication capabilities to interact with users or other systems.

From the sources

KeyID gives AI agents real email addresses, phone numbers, and verification handling in one API call. No human setup, no API keys. Agents self-provision via Ed25519 keypairs, then send/receive email, extract OTP codes, follow verification links, complete website signups with browser state persistence, and generate TOTP 2FA codes. Works as an MCP server (47 tools) with Claude, Cursor, and Windsurf — plus JS and Python SDKs. Shared domain pool keeps it free for 1,000 accounts.

One provision call and your agent operates on its own — real email inbox, phone number, web search, file storage, page hosting, 2FA codes, cron scheduling, encrypted vault, and a synthetic persona. All on domains and numbers reserved exclusively for your project. No human in the loop. https://keyid.ai/mcp ⧉ Add as remote MCP endpoint in Claude, Cursor, or any MCP client ext install keyid.keyid-agent-inbox ⧉ Or search "KeyID Agent Inbox" in the VS Code Marketplace npm install @keyid/sdk ⧉ Then: const agent = new KeyID(); await agent.provision(); pip install keyid ⧉ Then: agent = KeyID(); identity = agent.provision() POST https://keyid.ai/api/v1/provision ⧉ Requires a project key — use from…from keyid.ai

  Mcp-Agent – Build effective agents with Model Context Protocol2025 · github.com · ▲80

  Hey HN, I spent my xmas break building an agent framework called mcp-agent [1](https://github.com/lastmile-ai/mcp-agent) for Model Context Protocol [2]. It makes it easy to build AI apps with MCP servers, and implements every pattern from the popular Building Effective Agents blog [3] as well as OpenAI’s Swarm [4]. I’m sharing it early to get community feedback on where to take it from here, and to ask for contributions. For those who aren’t familiar with MCP, I think of it as a standardized interface to let AI communicate with software via tool calls, resources and…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
