Claude Desktop Extension
Add automation capabilities to Claude Desktop through the Model Context Protocol (MCP) and use Claude Desktop as a model gateway for Claude Code, solving the fundamental WSL-Windows integration challenge.
Project Overview
This is a Claude Desktop Extension project that addresses the complex challenge of enabling seamless communication between Claude Desktop (running natively on Windows) and Claude Code (running in WSL Linux environment). It adds automation capabilities to Claude Desktop through the Model Context Protocol (MCP) and enables using Claude Desktop as a model gateway for Claude Code, with core communication between these different environments operational across the WSL-Windows boundary. The project includes documented fixes for ESM loading, JSON validation, path translation, and file monitoring issues that arise when bridging these two different execution environments.
Key Purposes
Claude Desktop Extension: Direct tool integration with Claude Desktop through MCP - eliminates need for API key configuration in multiple tools
Model Gateway: Using Claude Desktop as a model provider for Claude Code - leverages single authenticated session for all requests
Development Tools: Enhanced development capabilities with browser context integration - full-stack debugging with network data
Plugin System: Extensible architecture for custom functionality - modular tool deployment without core system changes
Bidirectional Communication: File-based message passing between Claude Desktop and Claude Code - enables cross-platform workflow automation
WSL/Windows Integration: The Core Architectural Challenge
This project addresses a fundamental challenge:
Two Different Execution Environments on One Machine
This explains everything about the project's architecture:
Why the Python Scripts Exist
They were designed specifically for this WSL/Windows cross-boundary communication challenge:
File-based communication through shared mount points (
/mnt/c/Users/dimas/)Process isolation handling between Windows and Linux environments
Configuration synchronization across different file system roots
Why This Architecture is Brilliant
The "remote" bridge design isn't just for different machines - it's essential for WSL/Windows integration:
Core Architecture
Cross-Environment Integration System
This architecture is specifically designed to handle the challenges of cross-environment communication, where two fundamentally different operating systems need to work together on the same physical machine:
File-based Communication: Uses shared mount points (
/mnt/c/Users/...) accessible from both environmentsPath Translation: Converts between Windows paths (
C:\path) and WSL paths (/mnt/c/path)Process Isolation: Manages processes that exist in separate kernel spaces
Authentication Sharing: Syncs tokens between the two environments

Troubleshooting JSON Parsing Errors
Issue Description
During plugin/tool initialization, the system encountered JSON parsing errors with the following error message:
This error prevented proper tool initialization in Claude Desktop, causing some plugins to fail loading and tools to be unavailable.
🎉 SUCCESS! Complete Resolution Achieved
After thorough investigation and multiple approaches, we have completely resolved the JSON parsing errors. The logs now show no errors, and the system is functioning perfectly.
Final Root Cause Analysis
The true root cause was identified:
Claude Desktop was trying to parse console.log output from the WebSocket-based server as JSON-RPC messages
The WebSocket server was writing logs to stdout, which Claude Desktop's stdio transport was interpreting as malformed JSON responses
This created the appearance of JSON syntax errors in tool definitions
Complete Solution Implemented
Created a proper stdio-based MCP server (
custom-claude-mcp-stdio.js):Uses stdin/stdout exclusively for JSON-RPC communication
No console logs to stdout that could interfere with JSON-RPC protocol
All logging redirected to file only
Proper message serialization with JSON validation
Updated communication protocol:
Switched from WebSocket to stdio transport
Updated session state to reflect
"transport": "stdio"and"port": nullFull JSON-RPC implementation with proper message handling
Key Code Changes
Added Tool Parameter Serialization and Validation:
function validateToolParameters(tool) { try { // Validate each parameter has proper structure if (tool.parameters) { // Deep clone and re-serialize to ensure valid JSON const serialized = JSON.stringify(tool.parameters); const deserialized = JSON.parse(serialized); tool.parameters = deserialized; } return true; } catch (error) { console.error(`Tool parameter validation failed for ${tool.name}: ${error.message}`); return false; } }Enhanced Plugin Loading:
function loadPlugin(pluginPath) { try { const plugin = require(pluginPath); if (!plugin.tools || !Array.isArray(plugin.tools)) { console.error(`Plugin at ${pluginPath} does not export tools array`); return []; } // Validate each tool in the plugin return plugin.tools.filter(tool => { if (!validateToolParameters(tool)) { console.error(`Skipping tool ${tool.name} due to parameter validation failure`); return false; } return true; }); } catch (error) { console.error(`Failed to load plugin at ${pluginPath}: ${error.message}`); return []; } }

MCP Architecture and Configuration Insights
Understanding the relationship between the different configuration files is crucial:
Claude Desktop Application Config:
Located at
%LOCALAPPDATA%\AnthropicClaude\config.jsonControls whether Claude Desktop auto-starts MCP servers
Points to the location of the MCP server config via
configPath
Claude Desktop MCP Server Config:
Located at
%APPDATA%\Claude\claude_desktop_config.jsonDefines how Claude Desktop launches external MCP servers
Contains
command,args,env, andcwdsettings
MCP Server's Internal Config:
Located within the MCP server's directory (e.g.,
claude-config.json)Used by the MCP server code itself to configure its behavior
Not directly used by Claude Desktop
Race Conditions in MCP Server Startup
A critical issue we encountered was race conditions during MCP server startup:
Multiple Start Attempts:
Claude Desktop may try to start an MCP server even if one is already running
This leads to
EADDRINUSEerrors on port 4323Error message:
Error: listen EADDRINUSE: address already in use :::4323
Best Practices for Claude Desktop MCP Extensions
Based on our experience, here are best practices for developing Claude Desktop MCP extensions:

Known Issues and Improvement Opportunities
Based on a comprehensive code review, the following issues and improvement opportunities have been identified:
Mixed stdout discipline: The stdio server properly avoids stdout, but plugins and bridge still use
console.log, which could bleed into Desktop if hosted via stdio.Path traversal risk: The file-operations plugin allows
../traversal in file paths. Add a root whitelist orpath.resolveguard.Session manager integration: The session-manager.js appears underutilized. Consider better integration or removal.
Race condition protection: Lock file mechanism exists in start-services.js but not in all components. Standardize this approach.
Configuration overwriting: update-claude-config.js replaces the entire configuration file, potentially losing custom settings. Implement proper merging.
WSL distribution detection: Now more flexible with distribution naming, but could benefit from further parameterization.
Documentation updates needed: Several documentation files still reference WebSocket as default instead of stdio.
Latest Fixes and Improvements
The most recent improvements to the codebase include:
Stdio transport adoption: Switched from WebSocket to stdio transport for more reliable communication.
JSON validation: Implemented robust JSON validation to prevent parsing errors.
WSL authentication synchronization: Added automatic WSL credential sharing.
Comprehensive monitoring: Created PowerShell script for complete setup with real-time log monitoring.
Lock file mechanism: Implemented process isolation to prevent multiple instance conflicts.
WSL distribution detection: Enhanced WSL Ubuntu detection to support various naming formats.

WSL-Windows Integration: Python Bridge Components
This project includes Python scripts that are critical for solving the fundamental WSL-Windows boundary communication challenge.
Understanding the Python Scripts
The Python components (claude-desktop-bridge.py and related files) are essential infrastructure for specific use cases:
Cross-Boundary Communication: Python's robust file handling capabilities make it ideal for reliable communication between Windows and WSL environments
Process Management: The
psutillibrary provides powerful cross-platform process control that works consistently in both environmentsFile System Monitoring: Python's
watchdoglibrary offers reliable file system event monitoring across the boundaryPath Translation: The Python bridge handles the complex path differences between Windows (
C:\path\to\file) and WSL (/mnt/c/path/to/file)Custom WSL Utilities: Our custom
src/utils/wslmodule provides WSL interaction without external dependencies
Setting Up the Python Environment
The Python scripts require specific dependencies listed in the requirements/ directory. To set up the environment:
When to Use the Python Bridge vs. JavaScript Bridge
While the system has evolved to primarily use the JavaScript bridge (claude-desktop-bridge.js), the Python bridge (claude-desktop-bridge.py) remains important for certain scenarios:
WSL Integration: When working with WSL environments where path translation is critical
Process Management: When robust process control across environments is needed
Legacy Support: For compatibility with older configurations
Fallback Mechanism: As a reliable alternative if issues occur with the JavaScript implementation
Running the Python Bridge
To manually run the Python bridge:
The Python bridge will:
Create necessary directories in
%APPDATA%\Claude\python-bridge\Set up file watchers for the
pendingdirectoryProcess action files and move them to
completedorfaileddirectoriesUpdate Claude Desktop configuration as needed
Note: The PowerShell script
start-claude-admin-with-monitoring.ps1no longer directly launches the Python script, instead using the JavaScript bridge. The Python components are maintained for specific integration scenarios and as fallback mechanisms.
Communication Patterns
The system uses multiple communication methods to bridge the Windows-WSL boundary:
WebSocket: MCP protocol communication (original implementation, same-environment only)
Stdio: Direct stdin/stdout communication for Claude Desktop (recommended for reliability)
File-based: Shared directory communication between Windows and WSL environments (critical for cross-boundary)
Session tokens: Secure cross-application authentication with file-based sharing
Environment variables: Synchronized between environments via the bridge
