Intro

Setup time: 6-12 minutes

Key facts (verified)

  • GitHub: 922 stars · 61 forks · pushed 2026-05-09.
  • License: MIT · owner avatar + repo URL verified via GitHub API.
  • README-backed entrypoint: chatgpt --help.

Main

  • Start with history: creating ~/.chatgpt-cli enables per-thread message history and a sliding context window (README).

  • Use MCP for tool-augmented questions: inject tool results into the thread first, then ask follow-ups while the context stays local to the CLI.

  • Let the CLI manage MCP sessions: README explains it auto-handles servers that require mcp-session-id headers.

  • Prefer direct-download binaries for CI or locked-down machines: README shows curl -L -o chatgpt ... && chmod +x one-liners by OS/arch.

Source-backed notes

  • README documents MCP flags (--mcp, --mcp-tool, --mcp-params) and that results are injected as [MCP: <tool-name>] ... messages.
  • README includes Homebrew installation plus direct-download commands for multiple platforms/architectures.
  • README says creating ~/.chatgpt-cli enables history tracking stored under ~/.chatgpt-cli/history/.

FAQ

  • Do I need an API key?: Yes — README instructs setting OPENAI_API_KEY before running the CLI.
  • How do I keep conversation history?: Create ~/.chatgpt-cli; the CLI stores thread history under ~/.chatgpt-cli/history/ (README).
  • Does MCP work with servers requiring a session header?: README says the CLI automatically manages mcp-session-id for HTTP(S) MCP servers.
