+# ChatGPT MCP Server
+
+A local MCP server that allows Claude Code to ask ChatGPT for focused second-opinion help.
+
+## Purpose
+
+ChatGPT acts as a reviewer, planner, debugging assistant, and architecture advisor.
+Claude Code remains the primary coding agent with full control over files, commands, and decisions.
+
+## Non-Goals
+
+The server must not:
+
+- Modify files
+- Run shell commands
+- Access Git automatically
+- Deploy anything
+- Send whole repositories by default
+- Send secrets
+- Make autonomous decisions
+
+## Status
+
+Phase 0 complete — repository skeleton created.
+Implementation in progress.
