FREQUENTLY ASKED QUESTIONS

What tools does the Twilio MCP server expose?

The Twilio MCP Server exposes 36 tools across 3 categories: Read, Write, Other. Each tool can be individually controlled with Intercept policies.

How do I enforce policies on Twilio?

Download the policy scaffold, add rules (rate limits, argument validation, deny rules), then run Intercept as a proxy in front of the Twilio MCP server. Every tool call is evaluated against your YAML policy before execution.

Is the Twilio policy free to use?

Yes. All Intercept policies are open source under the Apache 2.0 licence. Download, modify, and deploy without restrictions.
