How to Use the TeleSign MCP in Windsurf

Q: Does the MCP Server support telephony checks for Windsurf?

Yes. You can check number activation status using checkdeactivation, or run a full suite of checks by running checktelesignstatus to ensure your connection is solid.

Q: If I have an issue with TeleSign and Windsurf, what should I look for?

Start by checking the API connectivity using checktelesignstatus. If that looks good, then try running a simple test like getting phone identity data with getphoneid to isolate where the failure is happening.

Finish identity checks fast with Windsurf's autonomous chaining and TeleSign intelligence.

Score Phone Risk in Windsurf

The `score_phone` tool instantly gives you a risk rating for any phone number. You feed it the number, and it spits out a score that tells you how likely it is to be fraudulent. This lets your agent decide if the user needs extra checks or if they can pass through. It’s crucial context for making high-confidence decisions.

Manage Verification Status via MCP Server

Need to know what happened with a previous check? Use `check_verification` to get the current status of an identity attempt. This tells you if a verification code was sent, or if it failed for some reason. It's useful for building retry logic into your workflow. Your agent checks this before trying to call `send_verification` again.

Get Phone Identity Data

The `get_phone_id` tool retrieves specific identity data about a phone number. This goes beyond just knowing the number; it provides context you can use for deeper validation. You'll find this works with other checks, like using `get_phone_type` to understand if the number is VoIP or standard mobile.
