 This remote MCP server function will provide Tools to your LLM that provide access to your Twilio account. We recommend the following considerations when giving clients access to your server:
 
-- Always the requires_approval field to ensure that there are no unintended actions taken within your account.
+- Always set the `requires_approval` field to ensure that there are no unintended actions taken within your account.
 - Use scoped permissions for your Twilio API Key. Not all endpoints support scoped permissions, but some do. See https://www.twilio.com/docs/iam/api-keys/restricted-api-keys for more information about which actions are supported per API Service.
 - To ensure privacy, do not use other MCP servers in conjunction with your Twilio MCP server.
