v0.3.1 · Rust · MIT

Indonesian stocks and ownership, in your terminal and your agent.

Quotes, fundamentals, technicals and KSEI shareholder data for every IDX stock. Tables for you, JSON for scripts, and an MCP server for AI agents.

$ npm install -g idx-cli

Downloads the checksum-verified release binary. Or run once with npx idx-cli.

$ curl -fsSL https://raw.githubusercontent.com/0xrsydn/idx-cli/main/install.sh | sh

Linux and macOS. Installs to ~/.local/bin without sudo.

$ cargo install idx-cli

Builds from source. Requires Rust 1.89+.

$ nix profile install github:0xrsydn/idx-cli

Bundles curl-impersonate and MuPDF for the ownership importers.

Install idx-cli and its MCP server for me by following https://idx.rasyidanaf.com/agents/install.md, then show me that it works.

Paste into Claude Code, Codex, Cursor or any coding agent. It installs idx, registers idx-mcp with itself, and asks before changing global config.

Quotes, OHLC history, financial statements and a screener. Technical, growth, valuation and risk analysis, and side-by-side compare.

Ownership

Who holds more than 1% of every listed company, from the monthly KSEI register. Month-over-month changes, entity search, cross-holdings. Sync once, query offline.

idx ownership entity "ANTHONI SALIM"

Agents

JSON whenever output is piped, errors as one JSON object, meaningful exit codes. Plus idx-mcp: 11 tools for any MCP client.

npx -y idx-mcp

Add idx to your agent

idx-mcp serves the same data over stdio. Our agent smoke test runs the Claude Code, Codex, opencode, pi, and Hermes setups against the real agents.

Ask it

"Who are BBCA's largest holders, and what changed last month?"

get_shareholdersget_ownership_changes

Or let your agent set it up

Install idx-cli and its MCP server for me by following https://idx.rasyidanaf.com/agents/install.md, then show me that it works.

stdout carries only data. Errors go to stderr as one JSON object, with exit codes an agent can act on.

3: not found, or no cached data offline
4: upstream unavailable, retry later
