Cursor Dados B3 multiplos

How to: Cursor Dados B3 multiplos

client:Cursor transport:streamable-http tool:multiplos

Add Dados B3 to Cursor

  1. 01

    Open ~/.cursor/mcp.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "dados-b3": {
      "url": "https://dadosb3.com/mcp/"
    }
  }
}
  1. 02

    Save the file and restart Cursor.

  2. 03

    Ask for something multiplos does. Cursor lists the server's tools on connect and calls multiplos itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Dados B3's identifier in your config matches the one above exactly.

Use .cursor/mcp.json in a project root instead to scope it to that project. Cursor merges both. Cursor docs

Set these first

Dados B3 will not start until these are set, so multiplos never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
