Frequently asked questions
Does the integration support checking Brazilian Tax Invoices (NFe)?
Yes. Your AI agent natively interacts with API v3 executing tools like 'listar_nfe', 'listar_nfce', and 'listar_nfse', actively checking their valid SEFAZ digital status and exact final values.
Can I actually create new Products or Contacts via my AI agent chat?
Yes. Utilizing the 'incluir_produto' and 'incluir_contato' tools, your AI can ingest unstructured raw data from an email or document and flawlessly mint it into structural tables on your Bling backend database.
Can I check my Accounts Receivable and open Boletos directly?
Absolutely. The agent holds explicit operational authority across the 'contas_receber' tool, strictly reporting open invoices, boletos, PIX items, and the total value currently pending payment globally.
Can I check stock levels across multiple warehouses?
Yes! Your agent can use the 'list_depositos' tool to see where your inventory is physically located across your different warehouses.
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.
