Install

Prebuilt binaries cover Linux x64/arm64 (static) and macOS arm64/x64. On Windows, use WSL.

Let your agent do it

Paste this into Claude Code, Codex, Cursor or another coding agent:

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

npm

npm install --global idx-cli
npx idx-cli --help            # or run without installing

The package downloads the checksum-verified release binary during postinstall. pnpm 10+ and bun skip install scripts by default; allow them with pnpm add --global --allow-build=idx-cli idx-cli or bun add --global --trust idx-cli.

Install script

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

Downloads the binary for your platform from GitHub Releases, verifies it against the release SHA256SUMS, and installs it into ~/.local/bin without sudo. Pin a version or change the directory:

curl -fsSL https://raw.githubusercontent.com/0xrsydn/idx-cli/main/install.sh | sh -s -- --version v0.3.1 --dir ~/bin

Cargo

cargo install idx-cli

Builds from source. Requires Rust 1.89 or newer.

Nix

nix profile install github:0xrsydn/idx-cli
nix run github:0xrsydn/idx-cli -- version   # or run without installing

The Nix package bundles the helper tools below.

Check it works:

idx version

Helper tools

Everyday use needs nothing else: stock data with the default MSN provider, price history, ownership sync and every local ownership query. A few commands call external tools:

Tool	Needed for
curl_chrome* from curl-impersonate, or IDX_CURL_IMPERSONATE_BIN	ownership discover and ownership import --url (IDX sits behind Cloudflare), and Yahoo fundamentals with IDX_PROVIDER=yahoo
mutool from MuPDF	importing legacy PDF ownership reports

The MCP server

idx-mcp installs the same ways (npx -y idx-mcp, cargo install idx-mcp, or nix profile install github:0xrsydn/idx-cli#idx-mcp). See MCP setup.

Shell completions

idx completions bash > ~/.local/share/bash-completion/completions/idx
