Perplexity

Automate Comms in Your Deploy Scripts

Add communication steps directly into your CI/CD pipelines. After a successful deployment, use Claude Code to call `send_sms` or `send_email` to notify your team. It's a single command that integrates with any shell script. You can also build health checks. Have a cron job run `check_authkey_status` and `check_balance` periodically, piping the output to your monitoring system. If something's wrong, trigger an alert using the `send_voice` tool.

Headless User and System Management

This MCP server makes it easy to script interactions with the Authkey service. Write a simple bash script to `send_bulk_sms` to a list of users from a CSV file. No need to write custom API integration code. A server-side process can also use Claude Code to `send_otp` when a new user signs up and then call `verify_otp` once the user submits their code. It's all done headlessly.

A Full Communication API on the CLI

Get direct, command-line access to the entire Authkey feature set. Check the delivery status of a critical message with `get_sms_status` or `get_email_status`. You get a clean, parsable output you can pipe to `jq` or other tools. Need to debug something? Just run a command to `list_sms_history` and grep for the number you're looking for. This is way faster than logging into a web dashboard.

Common questions about Authkey MCP in Claude Code

Run `claude mcp add --transport http authkey-mcp -- ` in your terminal. Replace `` with the server endpoint from Vinkius. Use `claude mcp list` to confirm it's connected.

Yes, that's exactly what it's for. Set up your Vinkius Authkey for Claude Code as a secret and call the Authkey tools from Claude Code within your workflow YAML file to send notifications or run checks.

It doesn't. Your main Vinkius Authkey for Claude Code is all you need. The MCP server connection is managed through Vinkius, so you don't expose your actual Authkey service credentials in your scripts or config files.

Just run a prompt like `claude 'check my authkey balance'`. It will execute the `check_balance` tool and print the result directly to your terminal.

The server processes the specific data needed for each tool, like a phone number for `send_sms` or an email address for `send_email`. Vinkius ensures your Authkey credentials are never exposed, and each server instance is isolated and ephemeral.
