What is the Bling ERP MCP Server?
Connect your Bling ERP API token to any AI agent and integrate Brazil's leading cloud-based business management system directly into your conversational workflow.
What you can do
- Contact & Product Operations — Create and list deeply nested catalogs of Contacts (Suppliers/Clients) and Products, tracing correct SKUs, categories, and warehouses.
- Order Processing — List Sales Orders bridging eCommerce streams directly to inventory, and explore incoming Purchase Orders to suppliers.
- Tax Documents (Brasil) — Monitor SEFAZ legal endpoints querying arrays for issued Product Invoices (NF-e), Consumer Invoices (NFC-e), and Service Invoices (NFS-e).
- Financial Ledgering — Pull aggregated general ledgers analyzing Accounts Payable, Accounts Receivable (Boletos/PIX), and strictly mapped financial groupings.
How it works
1. Subscribe to this server
2. Enter your Bling Access Token
3. Start running ERP operational logic from Claude, Cursor, or any MCP-compatible environment
Who is this for?
- E-Commerce Operators — list incoming sales orders and sync product stock intelligently using text commands.
- Financial Managers — consult outstanding accounts receivable and evaluate incoming bills instantly.
- Logistics Teams — search warehouse logic and map client logistics strictly prior to issuing an NF-e.

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 Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Bling ERP MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
