Implement MCP JSON-RPC handling and related I/O fixes: mcploader now handles initialize, tools/list and tools/call (implements add_both_numbers) and returns JSON-RPC responses; stdio-server.send serializes object messages before writing; console logging on WScript now writes muted messages to StdErr; bump jsonrpc2 version to 0.1.7 and reformat extract(). These changes enable proper MCP capability negotiation, tool discovery and invocation over stdio.
Change existsSync to resolve filenames relative to the current script directory by prepending require._getCurrentScriptDirectory() + "\\" to the provided filename before calling Scripting.FileSystemObject.FileExists. This ensures relative paths are correctly resolved when checking file existence (prevents false negatives when filenames are relative to the script).
Convert console._muted from a function to a boolean by invoking an IIFE during module initialization. This reads the WScript 'quiet' flag once and stores the result, and updates _echoCallback to reference the boolean (remove the function call). This simplifies usage and avoids repeated runtime checks.
Introduce a _muted() helper to check for a WScript "quiet" argument and avoid output when muted. Replace the old _echoDefault with a unified _echoCallback(params, type) that writes messages via WScript and respects the muted flag. Refactor _echo to build a params object (including params.message and scope), prepend the optional type, invoke _echoCallback, and push the composed message to _messages. Adjust callback invocation logic (remove the previous null check and inline handling).
Replace WScript.Echo with WScript.StdOut.WriteLine for WSH console output and reword provider comments to reflect requesting scripts (including LLM/AI services). Update core-js usage to app/assets/js/core-js-3.49.0.wsh and adjust related require paths (including squel), and remove the old core-js-3.26.1 minified file. Other minor changes include updates to bootstrap.bat and lib/http.js.
app.js: Add a _useStdin flag (via WScript.Arguments.Named.Exists("stdin")) and skip default echoing when stdin is in use; switch WScript.Echo to WScript.StdOut.WriteLine for proper stdout output. Remove separator comment lines before initializeConsole. bootstrap.js: Bump copyright year to 2026 and remove an obsolete/commented CORS-to-ADO registry tweak. These changes improve console output behavior for piped input and clean up bootstrap metadata and comments.
Introduces a TraceError class for enhanced stack tracing and logging, and adds a __export__ utility to wrap functions with error handling and naming. Also adds a console.trace method and updates bootstrap.js to use the new main function structure.
The UseObject function now accepts an optional fallback callback, which is invoked if the main callback throws an error. This improves error handling and allows custom recovery logic.
Corrects type checking for callback and position parameters in app.js and pipe-ipc.js, ensuring proper function behavior. Also updates the version string in pipe-ipc.js to 0.1.26.
Enhanced UseObject to accept a custom dispose function, improving resource management flexibility. Updated pipe-ipc.js to utilize this feature, preventing unintended disposal in repositionObject and ensuring correct stream handling. Bumped module version to 0.1.25.
