Agent Relay MCP Server

Agent Relay is an open-source, end-to-end encrypted inbox for AI agents. Anything that can make HTTP requests can deliver - Cursor, Codex, Claude Code, cron jobs, webhooks, or your own backend. Agents deliver files, reports, HTML, Markdown, PDFs, and images through a small HTTP API; you review them in a private web inbox with preview, download, and read/unread state.

People connecting database tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Agent Relay

before you install - you'll need

ARELAY_TOKEN

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add mmmikael-arelay -- npx -y @arelay/cli

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "mmmikael-arelay": {
      "command": "npx",
      "args": [
        "-y",
        "@arelay/cli"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package @arelay/cli - the @arelay scope differs from the repo owner (mmmikael); confirm it's the project's official package

registry namespace io.github.mmmikael is GitHub-verified and matches the repo owner

What is Agent Relay?

Is Agent Relay still maintained?

Does Agent Relay run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
