Agentline MCP
Agentline is an MCP server that lets AI agents use phone, SMS, voice, email, and 2FA capture through the Agentline API.
About
Agentline MCP connects AI agents to real-world communication channels: phone numbers, SMS, two-factor code capture, voice calls, and email. developers automating onboarding, smoke tests, or operator-style agents often stall on telecom APIs and OTP inboxes; this server centralizes those capabilities behind MCP so Claude Code or similar clients can rent numbers, send messages, and read verification codes in one integration. You need an Agentline API key from agentline.co, with test and live key prefixes documented in the server manifest. Staging or self-hosted deployments can override the default https://api.agentline.dev base URL. It fits products that are agents or APIs with human-notify loops, not static marketing sites that only need a contact form.
- Provision and use phone numbers, SMS, voice calls, and email from MCP tools
- 2FA capture flows for agents testing signup and login paths
- Requires AGENTLINE_API_KEY (ag_live_ or ag_test_ prefix); optional AGENTLINE_BASE_URL for staging or self-hosted API
- Python package via uvx (agentline-mcp on PyPI), stdio transport, version 0.1.1

What it does
Give your agent real phone numbers, SMS, voice, email, and 2FA capture through Agentline so automated flows can sign up, verify accounts, and notify users without you wiring Twilio by hand.
Who is it for?
Best when you're shipping agent products, auth test harnesses, or notification backends that must touch real carriers during development.
Skip if: Skip if you only need in-app chat or email through your own SMTP—Agentline is paid telecom infrastructure, not a generic SMTP helper.

FAQ
Who is Agentline MCP for?
Developers building AI agents or automated tests that must interact with real phone numbers, SMS, voice, email, or 2FA codes through MCP.
When should I use Agentline MCP?
Use it while building and integrating signup, verification, alerts, or voice workflows where mocks are not enough and you want the agent to drive live comms safely with test keys first.
How do I add Agentline MCP to my agent?
Set AGENTLINE_API_KEY in your environment, add the agentline-mcp stdio server (uvx) to MCP config, and optionally set AGENTLINE_BASE_URL for non-production API hosts.
