How to Use the TeleSign MCP in Claude Code

Q: How does TeleSign help Claude Code with fraud detection?

Claude Code runs scorephone as part of the pipeline. You can enforce that no code deployment or record creation happens unless the phone number passes a minimum risk score, stopping bad data at the source.

Q: Can I use the MCP Server with multiple verification channels in Claude Code?

Yes. Your pipeline can call sendpushverification first, and if that fails, it can fall back to calling sendsms. It’s all about scripting robust failover logic.

Q: Does the MCP Server support checking number availability for Claude Code?

You can check activation status using checkdeactivation before trying any messaging tool. Running checktelesignstatus first confirms that your entire server connection is up for the job.

Programmatic Risk Scoring

The `score_phone` tool lets you programmatically check the risk of a phone number in your scripts. You pipe the number into this function, and it outputs an integer score. You can then use standard shell logic to fail a build or generate a record based on that score's threshold.

Automated Verification Status Checks

Use `check_verification` in your scripts to get the latest status of a verification attempt. This is key for job runners, as it confirms if an SMS was successfully processed or if the user never responded. It prevents jobs from hanging because they think a step succeeded when it actually timed out.

Execute Multi-Method Verification

Your scripts can trigger multiple checks using `send_sms` and `send_voice_verification`. This is perfect for setting up failover logic—if SMS fails, the script automatically tries voice. This level of control ensures your CI/CD jobs aren't blocked by a single failure point.

Common questions about TeleSign MCP in Claude Code

Claude Code runs `score_phone` as part of the pipeline. You can enforce that no code deployment or record creation happens unless the phone number passes a minimum risk score, stopping bad data at the source.

The server exposes raw identity metrics and numerical scores from tools like `score_phone`. This structured data is designed to be easily parsed and used in shell scripts or job runners.

Yes. Your pipeline can call `send_push_verification` first, and if that fails, it can fall back to calling `send_sms`. It’s all about scripting robust failover logic.

You can check activation status using `check_deactivation` before trying any messaging tool. Running `check_telesign_status` first confirms that your entire server connection is up for the job.

Check the logs of the specific API call. If you're dealing with phone numbers, running `get_phone_type` can tell you if the number format is the source of your pipeline failure.
