chore: 重命名 Tools/godot-mcp-pro-v1.15.1 → Tools/godot-mcp-pro，更新 .mcp.json

- 去掉版本号后缀，路径更稳定（后续更新工具不必再改 .mcp.json）
- .mcp.json 指向新路径 server/build/index.js
- server 依赖已 npm install 就绪；node_modules 由 .gitignore 忽略，未入库

+# Installation Guide
+
+## Prerequisites
+
+- Godot 4.3+ (tested with 4.6)
+- Node.js 18+
+- An MCP-compatible AI client (Claude Code, Claude Desktop, etc.)
+
+## Step 1: Godot Plugin
+
+1. Copy the `addons/godot_mcp/` folder into your Godot project
+2. Open Project → Project Settings → Plugins
+3. Find "Godot MCP Pro" and click Enable
+4. You should see "MCP Server" appear in the bottom panel
+5. The status should show "Waiting for connection..."
+
+## Step 2: Node.js Server
+
+```bash
+cd server
+npm install
+npm run build
+```
+
+This creates the compiled server in `server/build/`.
+
+## Step 3: MCP Client Configuration
+
+### Claude Code (.mcp.json)
+
+```json
+{
+  "mcpServers": {
+    "godot-mcp-pro": {
+      "command": "node",
+      "args": ["/absolute/path/to/godot-mcp-pro/server/build/index.js"]
+    }
+  }
+}
+```
+
+### Custom Port
+
+Set the `GODOT_MCP_PORT` environment variable (default: 6505):
+
+```json
+{
+  "mcpServers": {
+    "godot-mcp-pro": {
+      "command": "node",
+      "args": ["/absolute/path/to/server/build/index.js"],
+      "env": { "GODOT_MCP_PORT": "6510" }
+    }
+  }
+}
+```
+
+Also update the port in `plugin.gd` (line 3: `const PORT := 6505`).
+
+## Troubleshooting
+
+### Plugin doesn't appear
+- Make sure the `addons/godot_mcp/` directory is inside your Godot project
+- Check that `plugin.cfg` exists in the directory
+
+### Connection fails
+- Verify the Godot editor is running with the plugin enabled
+- Check the bottom panel "MCP Server" tab for status
+- Ensure no firewall is blocking localhost port 6505
+
+### Tools timeout
+- Commands have a 30-second timeout
+- Large operations (full filesystem scan) may need the `max_depth` parameter
