check_verification
Check a verification code
Part of the Twilio MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents call check_verification to perform operations in Twilio. While the risk category is not fully classified, applying a rate limit gives you visibility into how often the tool is called and prevents unexpected bursts of activity from autonomous agents.
WHY ENFORCE A POLICY ON CHECK_VERIFICATION
Applying a policy to check_verification gives you an audit trail of every call an AI agent makes. Even for low-risk tools, visibility into agent behaviour helps you debug issues, optimise workflows, and maintain compliance with your organisation's security requirements.
RECOMMENDED POLICY
Apply a rate limit to control usage and monitor for unexpected behaviour.

What does the check_verification tool do?
Check a verification code. It is categorised as a Other tool in the Twilio MCP Server, which means it performs auxiliary operations.
How do I enforce a policy on check_verification?
Add a rule in your Intercept YAML policy under the tools section for check_verification. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Twilio MCP server.
What risk level is check_verification?
check_verification is a Other tool with low risk. Read-only tools are generally safe to allow by default.
Can I rate-limit check_verification?
Yes. Add a rate_limit block to the check_verification rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
How do I block check_verification completely?
Set action: deny in the Intercept policy for check_verification. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
What MCP server provides check_verification?
