Enhanced Tool Display System

Bibble v1.4.0 introduces a completely overhauled tool display system featuring:

• Dynamic Status Badges: Visual indicators showing tool execution status (running, completed, error)
• Boxed Parameter/Output Sections: Clearly delineated tool input/output for better readability
• Syntax Highlighted JSON: Beautiful formatting for JSON parameters and results
• Clickable URLs: Terminal hyperlinks for any URLs found in tool outputs
• Clipboard Support: Copy tool results directly to clipboard with interactive buttons
• Keyboard Shortcuts: Intuitive keyboard navigation for tool output exploration

These enhancements make working with MCP tools more intuitive and visually appealing. The new display system can be toggled using environment variables if compatibility issues arise.

Environment Variables

• BIBBLE_DISABLE_ENHANCED_TOOLS: Set to true to disable enhanced tool displays
• BIBBLE_TOOL_DISPLAY_MODE: Set to basic, compact, or full (default)

Configuration

Bibble stores its configuration in a .bibble directory in your home directory. The configuration includes:

• API keys
• Default model settings
• UI preferences
• MCP server configurations
• User guidelines (additional instructions for the AI)

MCP Integration

Bibble functions as an MCP client, allowing it to connect to MCP-compatible servers and use their tools. MCP (Model Context Protocol) is a protocol for connecting language models to external tools and services.

To configure MCP servers, use:

bibble config mcp-servers

Troubleshooting

Environment Diagnostics

Bibble includes built-in diagnostic tools to help troubleshoot common issues:

# Basic diagnostic information
bibble diagnose

# Detailed system analysis
bibble diagnose --verbose

The diagnostic command will check:

• Platform and terminal information
• Node.js, npm, and npx executable paths and versions
• Environment variables and PATH configuration
• MCP server connectivity issues

Common Issues

MCP Server Connection Failures

Problem: You see "Connection closed" errors when starting Bibble, especially in terminals other than Warp.

Solution:

1. Run bibble diagnose to check your environment
2. Ensure Node.js and npm are properly installed and accessible
3. Check that your PATH includes Node.js and npm directories
4. Try running from a different terminal (Command Prompt, PowerShell, or Git Bash on Windows)

Symptoms:

Failed to connect to MCP server "server-name": Connection closed

Advanced Troubleshooting:

• Run bibble diagnose --verbose for detailed information
• Try running node --version and npx --version in your terminal
• If using Windows, try running your terminal as Administrator
• Check if antivirus software is blocking Node.js processes

Terminal Compatibility

Problem: Bibble works in one terminal but not others.

Solution: Bibble v1.3.9+ includes multi-tier fallback systems for cross-terminal compatibility:

• Primary Strategy: Uses resolved executable paths
• Fallback Strategies: Direct commands, corepack, and bundled npm approaches
• Graceful Degradation: Continues working even if some servers fail

Supported Terminals:

• ✅ Warp Terminal
• ✅ Windows Terminal
• ✅ Hyper
• ✅ Command Prompt
• ✅ PowerShell
• ✅ Git Bash
• ✅ Most Unix terminals

System Prompt Visibility

Problem: Tools not appearing in the system prompt or model not recognizing available tools.

Solution:

1. Ensure you're using Bibble v1.4.0+ which fixes the tool visibility issue
2. Check that all MCP servers are properly connected with bibble diagnose
3. View the full system prompt with bibble system-prompt to confirm tools are listed
4. If tools are missing, try restarting Bibble or reconnecting to MCP servers

Node.js Installation Issues

Problem: Bibble can't find Node.js, npm, or npx.

Solutions:

1. Install Node.js: Download from nodejs.org
2. Check Installation:

   node --version
   npm --version
   npx --version

3. Path Issues: Add Node.js to your PATH environment variable
4. NVM Users: Make sure your Node.js version is activated
5. Windows Users: Try reinstalling Node.js with "Add to PATH" option checked

API Key Issues

Problem: API key errors or authentication failures.

Solutions:

1. Run the setup wizard: bibble setup
2. Manually set API keys: bibble config api-key
3. Check your API key is valid and has sufficient credits
4. Verify the correct API endpoint is configured

Performance Issues

Problem: Slow startup or response times.

Solutions:

1. Check your internet connection
2. Try a different model or provider
3. Reduce the number of enabled MCP servers
4. Clear chat history if it's very large: bibble history clear

Getting Help

If you're still experiencing issues:

1. Run Diagnostics: bibble diagnose --verbose
2. Check Logs: Look for error messages in the terminal output
3. Update Bibble: npm install -g @pinkpixel/bibble@latest
4. Check GitHub Issues: Visit the GitHub repository
5. Report Bugs: Create a new issue with:
   • Your operating system and terminal
   • Output from bibble diagnose --verbose
   • Steps to reproduce the issue
   • Error messages or unexpected behavior

Version Compatibility
