Connector for ChatGPT

Dados B3 inside ChatGPT

The connector brings public data from the CVM and B3 into ChatGPT. It returns data only: no recommendation to buy or sell.

Connector address

https://dadosb3.com/mcp/chatgpt/

Add this address as a connector in ChatGPT. It speaks MCP over Streamable HTTP and needs no key.

What it does

Every answer carries the link to the public page it came from. The data comes from CVM open data and from B3. It is descriptive data, not investment advice.

The same data is available in Claude and other MCP clients: connector page.

Sources: CVM (open data, ODbL) and B3 (COTAHIST). Not affiliated with B3 or the CVM. Not investment advice.
