🧠 Claude Thread Continuity MCP Server

Never lose context again! This MCP server automatically saves and restores project state when Claude threads hit token limits, ensuring seamless conversation continuity.

🚀 Features

🔄 Automatic State Persistence - Auto-saves project context during conversations
⚡ Seamless Restoration - Instantly restore full context when starting new threads
🛡️ Smart Validation - Prevents project fragmentation with intelligent name checking
🔒 Privacy First - All data stored locally on your machine
🎯 Zero Configuration - Works invisibly once set up
📊 Smart Triggers - Auto-saves on file changes, decisions, milestones
🗂️ Multi-Project Support - Manage multiple concurrent projects

✨ NEW: Anti-Fragmentation System

Version 1.1 introduces intelligent project validation to prevent the common issue of accidentally creating multiple similar projects:

🔍 Fuzzy Name Matching - Detects similar project names (70% similarity threshold)
⚠️ Validation Warnings - Suggests consolidation when similar projects exist
💪 Force Override - Bypass validation when genuinely different projects needed
🎯 Configurable Thresholds - Adjust sensitivity for your workflow

Example Validation in Action

❌ Project "Hebrew Speaking Evaluation MVP" blocked
✅ Similar project found: "Hebrew Evaluation MVP" (85% similar)
🎯 Recommendation: Update existing project or use force=true

⚡ Quick Start

# 1. Clone the repository
git clone https://github.com/peless/claude-thread-continuity.git
cd claude-thread-continuity

# 2. Install dependencies
pip install -r requirements.txt

# 3. Test the enhanced server
python3 test_server.py

# 4. Add to Claude Desktop config
# See setup instructions below

🛠️ Installation

1. Install the MCP Server

# Create permanent directory
mkdir -p ~/.mcp-servers/claude-continuity
cd ~/.mcp-servers/claude-continuity

# Copy files (or clone repo to this location)
# Place server.py and requirements.txt here

2. Configure Claude Desktop

Edit your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\\Claude\\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

Add this configuration:

{
  "mcpServers": {
    "claude-continuity": {
      "command": "python3",
      "args": ["~/.mcp-servers/claude-continuity/server.py"],
      "env": {}
    }
  }
}

3. Restart Claude Desktop

Close and reopen Claude Desktop. The continuity tools will now be available automatically.

🎯 How It Works

Automatic Context Saving

The server automatically saves project state when:

✅ Files are created or modified
✅ Technical decisions are made
✅ Project milestones are reached
✅ Every 10 messages (fallback)

Smart Validation Process

Before saving, the system:

Checks for Similar Names - Uses fuzzy matching to find existing projects
Calculates Similarity - Compares project names with 70% threshold
Provides Recommendations - Suggests consolidation or renaming
Allows Override - Use force: true for edge cases

Context Restoration

When starting a new thread:

Load Project: load_project_state: project_name="your-project"
Full Context Restored: All technical decisions, files, and progress restored
Continue Seamlessly: Pick up exactly where you left off

🔧 Available Commands

Command	Description	NEW in v1.1
`save_project_state`	Save current project state	✨ Now with validation
`load_project_state`	Restore full project context
`list_active_projects`	View all tracked projects
`get_project_summary`	Get quick project overview
`validate_project_name`	Check for similar project names	✨ NEW
`auto_save_checkpoint`	Triggered automatically

💡 Usage Examples

Starting a New Project (with Validation)

save_project_state: project_name="my-web-app", current_focus="Setting up React components", technical_decisions=["Using TypeScript", "Vite for bundling"], next_actions=["Create header component", "Set up routing"]

Checking Name Before Creating

validate_project_name: project_name="my-webapp", similarity_threshold=0.7

Force Override When Needed

save_project_state: project_name="my-web-app-v2", force=true, current_focus="Starting version 2"

Continuing After Token Limit

load_project_state: project_name="my-web-app"

Viewing All Projects

list_active_projects

🗂️ Data Storage

Project states are stored locally at:

~/.claude_states/
├── project-name-1/
│   ├── current_state.json
│   └── backup_*.json
└── project-name-2/
    ├── current_state.json
    └── backup_*.json

Privacy: Everything stays on your machine
Backups: Automatic backup rotation (keeps last 5)
Format: Human-readable JSON files
Validation: Metadata tracks validation bypass status

🏗️ Project State Structure

Each saved state includes:

{
  "project_name": "my-project",
  "current_focus": "What you're working on now",
  "technical_decisions": ["Key choices made"],
  "files_modified": ["List of files created/changed"],
  "next_actions": ["Planned next steps"],
  "conversation_summary": "Brief context summary",
  "last_updated": "2025-06-15T10:30:00Z",
  "version": "1.1",
  "validation_bypassed": false
}

🛡️ Validation Configuration

Default Settings

Similarity Threshold: 70% (0.7)
Comparison Method: Fuzzy string matching
Auto-save Behavior: Bypasses validation (uses force=true)

Customizing Validation

validate_project_name: project_name="test-project", similarity_threshold=0.8

Higher threshold = stricter matching (0.9 = 90% similar required) Lower threshold = looser matching (0.5 = 50% similar triggers warning)

🔍 Troubleshooting

Tools Not Appearing

Check Claude Desktop logs
Verify Python 3 is in your PATH: python3 --version
Validate JSON config syntax
Restart Claude Desktop completely

Testing the Enhanced Server

cd ~/.mcp-servers/claude-continuity
python3 test_server.py

The test suite now includes validation testing and will report:

✅ Basic functionality tests
✅ Project validation tests
✅ Fuzzy matching accuracy
✅ Force override functionality

Common Issues

Validation Too Strict: Lower the similarity threshold or use force=true

Permission Errors:

chmod +x ~/.mcp-servers/claude-continuity/server.py

Python Path Issues: Update the config to use full Python path:

{
  "command": "/usr/bin/python3",
  "args": ["~/.mcp-servers/claude-continuity/server.py"]
}

🧪 Development

🚀 Why This Matters

Before v1.1: 😫 Hit token limit → Lose all context → Re-explain everything → Lose momentum

Common Problem: 😤 Create "Hebrew MVP", then "Hebrew Evaluation MVP", then "Hebrew Speaking MVP" → Context scattered across multiple projects

After v1.1: 😎 Hit token limit → Start new thread → load_project_state → Continue seamlessly + Smart validation prevents fragmentation

Perfect for:

🏗️ Complex Development Projects - Keep track of architecture decisions without fragmentation
📚 Learning & Research - Maintain context across study sessions with consistent naming
✍️ Writing Projects - Remember plot points without creating duplicate character projects
🔧 Multi-session Debugging - Preserve debugging state with clear project organization
