Implementation Reference

• src/mcp/tools/retrieval.js:428-451 (handler)

  The handler for the 'localnest_read_file' tool is registered using `registerJsonTool` in `src/mcp/tools/retrieval.js`. It takes a file path, start line, and end line, then calls `workspace.readFileChunk` to retrieve the content, which is then formatted by `normalizeReadFileChunkResult`.

  registerJsonTool(
    'localnest_read_file',
    {
      title: 'Read File',
      description: 'Read a bounded chunk of a file with line numbers.',
      inputSchema: {
        path: z.string(),
        start_line: z.number().int().min(1).default(1),
        end_line: z.number().int().min(1).default(defaultMaxReadLines)
      },
      annotations: {
        readOnlyHint: true,
        destructiveHint: false,
        idempotentHint: true,
        openWorldHint: false
      }
    },
    async ({ path, start_line, end_line }) => normalizeReadFileChunkResult(
      await workspace.readFileChunk(path, start_line, end_line, 800),
      path,
      start_line,
      end_line
    )
  );
