description: 'ThetaData ships an official MCP (Model Context Protocol) server built into Theta Terminal
  v3, exposing the full v3 market-data API to LLM CLIs (documented for Claude CLI and Gemini CLI) over
  SSE at http://127.0.0.1:25503/mcp/sse. The server is local-only: it requires the Theta Terminal running
  on the user''s machine and a paid ThetaData subscription, so the live tools/list manifest cannot be
  introspected anonymously. The tool list below is a candidate list derived one-per-operationId from the
  published OpenAPI 3.1 spec, per the docs statement that the MCP server exposes the full v3 API; actual
  published tool names/schemas need authenticated local introspection. A community npm MCP server (thetadatadx-mcp-server,
  publisher userfrm) also exists.'
server:
