Idx

Idx is an open-source Indonesian stock market tool providing quotes, fundamentals, technicals, and news.

Idx is an open-source binary designed for the Indonesia Stock Exchange that delivers quotes, history, fundamentals, technicals, the KSEI register of holders above 1 percent, and news. It operates through three interfaces including a table for humans, JSON output for scripts, and an MCP server with 36 tools for AI agents like Claude Code, Cursor, and ChatGPT. The tool aggregates data from Yahoo Finance, MSN Money, IDX, Indo Premier, Kontan, and CNBC Indonesia without averaging conflicting sources. It also imports KSEI ownership files into a local SQLite database for historical tracking. The software is free, requires no API keys, includes an offline cache mode, and operates under an MIT license.
