Frequently asked questions
How do I securely pass the Stark Bank ECDSA Private Key to MCP?
Inside Stark Bank, when you generate your API project, the website will generate a Public/Private Keypair or ask you to provide one. You must grab the Private Key (often starting with -----BEGIN EC PRIVATE KEY-----) and paste that entire raw multiline text into the STARK_PRIVATE_KEY input inside the MCP client perfectly as it is.
Can the bot process Corporate Card requests automatically?
Yes! If you instruct the agent to orchestrate the generation using the tool stark_create_corporate_card, the API instantly spins up a valid, active Corporate Virtual Card attached to your Master Balance in real-time.
How does the Stark Bank transfer function differ from basic gateway Pix?
Stark Transfer allows hyper granular outbounds. Instead of just pushing a basic Pix key, the stark_create_transfer can route massive payrolls, TED systems tracking BankCode, ISPB nodes and branch validation—giving you raw underlying banking protocol access.
Will Stark API throttle the connection if the Agent lists too many historic Boletos?
StarkBank allows huge enterprise-grade API ceilings per second. Pulling hundreds of statements using stark_list_boletos naturally respects rate limits easily while functioning inside LLM chat turns.
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.
