-## Recommendation
+## Claude Code Integration
 
-Install [Claude Code](https://code.claude.com/docs/en/setup) for AI-assisted LaTeX writing. Run it in the integrated terminal and let it edit your `.tex` files directly — changes sync to Overleaf in real-time.
+LatteX has built-in [Claude Code](https://docs.anthropic.com/en/docs/claude-code) integration via MCP (Model Context Protocol). When you open a project, LatteX automatically:
+
+1. Syncs all project files to a local temp directory
+2. Writes a `.mcp.json` config that registers the LatteX MCP server
+3. Writes `.claude/CLAUDE.md` with project context and tool documentation
+4. Pre-approves all MCP tool permissions in `.claude/settings.json`
+
+### Usage
+
+1. Open a project in LatteX
+2. Open the integrated terminal (Cmd+`)
+3. Run `claude` — Claude Code auto-discovers the MCP server and has full access to the project
+
+Claude Code can then:
+- **Edit `.tex` files** directly on disk — changes sync to Overleaf in real-time via bidirectional file sync
+- **Read and respond to comments** — `get_comments`, `reply_to_comment`, `resolve_comment`
+- **Compile and debug** — `compile_latex`, `get_compile_errors`, `get_compile_warnings`
+- **Use project chat** — `get_chat_messages`, `send_chat_message`
+- **List project files** — `list_project_files`
+
+### Available MCP Tools
+
+| Tool | Description |
+|------|-------------|
+| `get_comments` | Read comments, optionally filtered by file |
+| `resolve_comment` | Resolve a comment thread |
+| `reopen_comment` | Reopen a resolved comment |
+| `reply_to_comment` | Reply to a comment thread |
+| `delete_comment` | Permanently delete a comment thread |
+| `get_chat_messages` | Read project chat history |
+| `send_chat_message` | Send a message to project chat |
+| `list_project_files` | List all project files with sizes |
+| `compile_latex` | Trigger server-side LaTeX compilation |
+| `get_compile_errors` | Get parsed errors from last compile |
+| `get_compile_warnings` | Get parsed warnings from last compile |
+| `get_compile_log` | Get raw compile log output |
+
+### Example Workflow
+
+```
+> claude
+
+You: Review the comments on this paper and address the feedback
+
+Claude: [calls get_comments] I see 3 comments...
+        [edits sections/intro.tex to address feedback]
+        [calls reply_to_comment] "Revised the introduction as suggested."
+        [calls resolve_comment]
+        [calls compile_latex] Compilation successful, no errors.
+```
+
+No configuration needed — everything is set up automatically when you open a project.
