codeFileRead
Reads code files with line numbers to verify actual line counts for editing operations, helping users confirm file structure before making changes.
Instructions
讀取程式碼檔案並顯示行號，用於確認檔案實際行數以便編輯操作。(如果不影響編譯器的話，不需要針對縮排等小問題修改。提醒User就好了)

Implementation Reference
- tools/csFileReader.ts:14-39 (handler)Core handler logic: reads the specified file, checks existence, splits into lines, adds padded line numbers to each line, joins back, handles errors.
static async readFileWithLineNumbers(filePath: string): Promise<string> { try { // 檢查檔案是否存在 if (!existsSync(filePath)) { return `錯誤: 檔案 ${filePath} 不存在`; } // 讀取檔案內容 const content = await fs.readFile(filePath, 'utf8'); const lines = content.split(/\r?\n/); // 計算行號寬度 (最大行號的位數) const lineNumberWidth = lines.length.toString().length; // 為每行添加行號 const numberedLines = lines.map((line, index) => { const lineNumber = (index + 1).toString().padStart(lineNumberWidth, '0'); return `${lineNumber}: ${line}`; }); return numberedLines.join('\n'); } catch (error) { console.error(`讀取檔案時發生錯誤: ${error}`); return `讀取檔案時發生錯誤: ${error instanceof Error ? error.message : '未知錯誤'}`; } } - main.ts:70-85 (registration)Registers the 'codeFileRead' MCP tool with name, description, input schema (filePath: string), and thin async handler that delegates to myFileReader.readFileWithLineNumbers and formats MCP response.
server.tool("codeFileRead", "讀取程式碼檔案並顯示行號，用於確認檔案實際行數以便編輯操作。(如果不影響編譯器的話，不需要針對縮排等小問題修改。提醒User就好了)", { filePath: z.string() }, async ({ filePath }) => { try { const result = await myFileReader.readFileWithLineNumbers(filePath); return { content: [{ type: "text", text: result }] }; } catch (error) { return { content: [{ type: "text", text: `讀取檔案失敗: ${error instanceof Error ? error.message : "未知錯誤"}` }] }; } } ); - main.ts:72-72 (schema)Input schema validation using Zod for the tool: requires 'filePath' as string.
{ filePath: z.string() }, - main.ts:8-8 (helper)Import of the myFileReader class used by the tool handler.
