Frequently asked questions
How do I find my Authkey API Key?
Log in to your account at authkey.io, navigate to the dashboard, and copy your unique Authkey.
Can I verify OTPs via AI?
Yes! The verify_otp tool allows your agent to confirm security codes by providing the Log ID from the original request and the code entered by the user.
How do I check my remaining credits?
Use the check_balance tool to retrieve high-fidelity real-time credit status for SMS, Voice, and Email channels directly through your agent.
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.
