Built for headless automation

Six capabilities your agent needs to handle email — from inbox creation to OTP extraction — without touching a browser.

One line installs it in Claude, Claude Code, or any MCP-compatible agent: npx emptyinbox-mcp. No config file.

Import the spec directly into OpenAI GPTs, LangChain, CrewAI, or any OpenAPI-compatible framework — instant integration.

Wait for a verification email, then extract the code — one MCP call handles the full OTP flow. Your agent stays unblocked.

One static key works from CI, containers, and cloud functions — no browser session, no OAuth dance.

Buy inbox capacity with USDT via Blockonomics. No credit card, no KYC — pay and use immediately.

Messages purge automatically. Zero retention risk, no cleanup scripts — your agent can move on without looking back.

EmptyInbox works wherever you run code — shell scripts, browsers, or any HTTP client.
