session-buddy 0.10.1

MCP server for Claude session management and conversation memory

Session Buddy

A Session Management MCP Server for Claude Code

A dedicated MCP server that provides comprehensive session management functionality for Claude Code sessions across any project.

Features

• 🚀 Session Initialization: Complete setup with UV dependency management, project analysis, and automation tools
• 🔍 Quality Checkpoints: Mid-session quality monitoring with workflow analysis and optimization recommendations
• 🏁 Session Cleanup: Comprehensive cleanup with learning capture and handoff file creation
• 📊 Status Monitoring: Real-time session status and project context analysis
• ⚡ Auto-Generated Shortcuts: Automatically creates /start, /checkpoint, and /end Claude Code slash commands

🚀 Automatic Session Management (NEW!)

For Git Repositories:

• ✅ Automatic initialization when Claude Code connects
• ✅ Automatic cleanup when session ends (quit, crash, or network failure)
• ✅ Intelligent auto-compaction during checkpoints
• ✅ Zero manual intervention required

For Non-Git Projects:

• 📝 Use /start for manual initialization
• 📝 Use /end for manual cleanup
• 📝 Full session management features available on-demand

The server automatically detects git repositories and provides seamless session lifecycle management with crash resilience and network failure recovery. Non-git projects retain manual control for flexible workflow management.

Available MCP Tools

This server provides 79+ specialized tools organized into 11 functional categories. For a complete list of tools, see the MCP Tools Reference.

Core Session Management:

• start - Comprehensive session initialization with project analysis and memory setup
• checkpoint - Mid-session quality assessment with workflow analysis
• end - Complete session cleanup with learning capture
• status - Current session overview with health checks
• permissions - Manage trusted operations to reduce permission prompts

Memory & Conversation Search:

• reflect_on_past - Semantic search through past conversations using local AI embeddings
• store_reflection - Store insights with tagging and embeddings
• quick_search - Fast overview search with count and top results
• get_more_results - Pagination support for large result sets

Knowledge Graph (DuckPGQ):

• Entity and relationship management for project knowledge
• SQL/PGQ graph queries for complex relationship analysis
• See Knowledge Graph Integration Guide

All tools use local processing for privacy, with DuckDB vector storage (FLOAT[384] embeddings) and ONNX-based semantic search requiring no external API calls.

🚀 Integration with Crackerjack

Session-mgmt includes deep integration with Crackerjack, the AI-driven Python development platform:

Key Features:

• 📊 Quality Metrics Tracking: Automatically captures and tracks quality scores over time
• 🧪 Test Result Monitoring: Learns from test patterns, failures, and successful fixes
• 🔍 Error Pattern Recognition: Remembers how specific errors were resolved and suggests solutions

Example Workflow:

1. 🚀 Session-mgmt start - Sets up your session with accumulated context from previous work
2. 🔧 Crackerjack runs quality checks and applies AI agent fixes to resolve issues
3. 💾 Session-mgmt captures successful patterns and error resolutions
4. 🧠 Next session starts with all accumulated knowledge

For detailed information on Crackerjack integration, see Crackerjack Integration Guide.

Installation

From Source

# Clone the repository
git clone https://github.com/lesleslie/session-buddy.git
cd session-buddy

# Install with all dependencies (development + testing)
uv sync --group dev

# Or install minimal production dependencies only
uv sync

# Or use pip (for production only)
pip install session-buddy

MCP Configuration

Add to your project's .mcp.json file:

{
  "mcpServers": {
    "session-mgmt": {
      "command": "python",
      "args": ["-m", "session_buddy.server"],
      "cwd": "/path/to/session-buddy",
      "env": {
        "PYTHONPATH": "/path/to/session-buddy"
      }
    }
  }
}

Alternative: Use Script Entry Point

If installed with pip/uv, you can use the script entry point:

{
  "mcpServers": {
    "session-mgmt": {
      "command": "session-buddy",
      "args": [],
      "env": {}
    }
  }
}

Dependencies: Requires Python 3.13+. For a complete list of dependencies, see pyproject.toml. Recent changes include pinning FastAPI to <0.121.0 to prevent circular import bugs and removing sitecustomize.py for improved startup reliability.

Usage

Once configured, the following slash commands become available in Claude Code:

Primary Session Commands:

• /session-buddy:start - Full session initialization
• /session-buddy:checkpoint - Quality monitoring checkpoint with scoring
• /session-buddy:end - Complete session cleanup with learning capture
• /session-buddy:status - Current status overview with health checks

Auto-Generated Shortcuts: After running /session-buddy:start once, these shortcuts are automatically created:

• /start → /session-buddy:start
• /checkpoint [name] → /session-buddy:checkpoint
• /end → /session-buddy:end

These shortcuts are created in ~/.claude/commands/ and work across all projects

Memory & Search Commands:

• /session-buddy:reflect_on_past - Search past conversations with semantic similarity
• /session-buddy:store_reflection - Store important insights with tagging
• /session-buddy:quick_search - Fast search with overview results
• /session-buddy:permissions - Manage trusted operations

For running the server directly in development mode:

python -m session_buddy.server
# or
session-buddy

Memory System

Built-in Conversation Memory:

• Local Storage: DuckDB database at ~/.claude/data/reflection.duckdb
• Embeddings: Local ONNX models for semantic search (no external API needed)
• Privacy: Everything runs locally with no external dependencies
• Cross-Project: Conversations tagged by project context for organized retrieval

Search Capabilities:

• Semantic Search: Vector similarity matching with customizable thresholds
• Time Decay: Recent conversations prioritized in results
• Filtering: Search by project context or across all projects

Data Storage

This server manages its data locally in the user's home directory:

• Memory Storage: ~/.claude/data/reflection.duckdb
• Session Logs: ~/.claude/logs/
• Configuration: Uses pyproject.toml and environment variables

Recommended Session Workflow

1. Initialize Session: /session-buddy:start - Sets up project context, dependencies, and memory system
2. Monitor Progress: /session-buddy:checkpoint (every 30-45 minutes) - Quality scoring and optimization
3. Search Past Work: /session-buddy:reflect_on_past - Find relevant past conversations and solutions
4. Store Important Insights: /session-buddy:store_reflection - Capture key learnings for future sessions
5. End Session: /session-buddy:end - Final assessment, learning capture, and cleanup
