Cline Dados B3 etf

How to: Cline Dados B3 etf

client:Cline transport:streamable-http tool:etf

Add Dados B3 to Cline

01
Open ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json and merge this in. Keep any servers already there.

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

02
Save the file and restart Cline.
03
Ask for something etf does. Cline lists the server's tools on connect and calls etf itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that Dados B3's identifier in your config matches the one above exactly.

Cline's MCP Servers pane edits this file for you if you would rather not find it. Cline docs

Set these first

Dados B3 will not start until these are set, so etf 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.
