Agentline
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.
Overview
Agentline is an MCP server for the Build phase that lets AI agents use phone, SMS, voice, email, and 2FA capture through the Agentline API.
What is this MCP server?
- 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
- MCP server version 0.1.1
- Required secret: AGENTLINE_API_KEY
- Default API host: https://api.agentline.dev
What problem does it solve?
Building agent flows that need real SMS, calls, or OTP codes forces you to juggle multiple telecom APIs and manual phone testing.
Who is it for?
Solo builders shipping agent products, auth test harnesses, or notification backends that must touch real carriers during development.
Skip if: Builders who only need in-app chat or email through their own SMTP—Agentline is paid telecom infrastructure, not a generic SMTP helper.
What do I get? / Deliverables
After registration, your agent can allocate numbers, send messages, place calls, and capture 2FA via MCP tools backed by your Agentline key.
- MCP-accessible phone, SMS, voice, email, and 2FA operations for agent-driven workflows
- Configurable API base URL for staging or self-hosted Agentline deployments
Recommended MCP Servers
Journey fit
Build is where solo products need telephony and messaging wired into agent workflows, prototypes, and integration tests. Integrations is the right shelf because Agentline is an external comms API exposed as MCP tools, not a UI or docs artifact.
How it compares
Telecom and inbox MCP bridge, not a CRM skill or a local mock SMS server.
Common Questions / FAQ
Who is Agentline 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?
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 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.
