[MCP Store] Listing request: Twelve Data (remote MCP server, OAuth)

Google Antigravity

Hi Antigravity team,

We’d like Twelve Data to be listed in the Antigravity MCP Store (Add MCP Server).

Twelve Data is a market data provider. The MCP server gives agents real-time and historical prices, technical indicators, fundamentals and reference data for stocks, ETFs, forex and crypto. It has 25 read-only tools, including search_symbol, get_quote, get_time_series and get_technical_indicator.

  • Server name: twelvedata
  • Server URL: https://mcp.twelvedata.com/mcp
  • Transport: Streamable HTTP, nothing to install locally
  • Auth: OAuth. Antigravity is identified through its client ID metadata document (antigravity.google), and dynamic client registration is also supported. Users sign in with a Twelve Data account; a free plan is available.
  • Registry: com.twelvedata/mcp in the official MCP Registry
  • Repo: https://github.com/twelvedata/mcp

Config:

{
  "mcpServers": {
    "twelvedata": {
      "serverUrl": "https://mcp.twelvedata.com/mcp"
    }
  }
}

We tested it in Antigravity 2.0 on macOS on 2026-11-09: the server added through mcp_config.json, OAuth sign-in, 25 tools enabled, symbol search, quote, time series and RSI prompts all answered through the twelvedata tools, and the session survived an app restart without signing in again.

Happy to provide an icon, a test account or anything else you need.

Pavel Osetrov, Twelve Data
