Frequently asked questions
Can I check the delivery status of a specific message via AI?
Yes! Use the get_message_details tool and provide the Message SID. Your agent will retrieve the real-time delivery status (e.g., sent, delivered, failed) and other metadata.
How do I find a new available phone number in the US?
Run the search_available_numbers query and set the countryCode parameter to 'US'. The agent will return a list of phone numbers available for purchase in that region.
Is it possible to see the costs associated with my messaging usage?
Absolutely. Use the get_usage_statistics tool to retrieve detailed usage records and associated costs for your SMS and voice services directly from TextGrid.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
