## Tool Routing

`MCPToolRouter` exposes 9 IDE-specific tools + all mcpbridge tools:
`MCPToolRouter` exposes exactly 9 IDE-specific tools (it does NOT expose all mcpbridge tools):

| IDE Tool | Implementation |
|----------|---------------|
| `openFile` | `xed --line N path` |
| `getDiagnostics` | Proxies to `XcodeListNavigatorIssues` with optional glob filter by file |
| `executeCode` | Proxies to `ExecuteSnippet` via mcpbridge |
| `getDiagnostics` | Wraps `XcodeListNavigatorIssues` mcpbridge tool with optional glob filter by file |
| `executeCode` | Wraps `ExecuteSnippet` mcpbridge tool |
| `getCurrentSelection` / `getLatestSelection` | Returns current editor selection from `EditorContext` |
| `getOpenEditors` | Lists open editors via AppleScript |
| `getWorkspaceFolders` | Returns detected workspace paths |
| `checkDocumentDirty` | Checks unsaved changes via AppleScript |
| `saveDocument` | Saves a document via AppleScript |

Diff tools (`openDiff`, `closeDiff`, `closeAllDiffTabs`) are intentionally not exposed — Claude Code falls back to its built-in terminal diff view, which gives the user proper accept/reject control.
Only these 9 tools are exposed to Claude Code clients. Tool calls for any other tool name will fail with "Unknown tool" error.

The `getDiagnostics` and `executeCode` tools internally call mcpbridge tools (`XcodeListNavigatorIssues` and `ExecuteSnippet` respectively) with `tabIdentifier` auto-injected, but no other mcpbridge tools are accessible.

All other tool calls are proxied to mcpbridge with `tabIdentifier` auto-injected.
