# ATI + Codex CLI: MCP Provider Example
#
# Codex already has a built-in shell — it runs commands directly.
# We just give it an AGENTS.md that explains ATI commands and let it work.
#
# Usage:
#   ./mcp_agent.sh
#   ./mcp_agent.sh "Research the rust-lang/rust repo and explain its module system"
#
# Requires:
#   OPENAI_API_KEY environment variable
#   @openai/codex installed (npm i -g @openai/codex)
#   ATI binary on PATH
