Overview

Claude Session Coordinator provides a storage adapter-based MCP server that enables multiple Claude sessions to:

• Share state and coordinate work

• Avoid conflicts when working in parallel

• Track progress across sessions

• Support multiple workflow patterns

Core Philosophy: Flexible primitives over opinionated workflows. The server provides simple, universal building blocks that support any coordination pattern.

Project Structure

This is a monorepo containing:

• packages/mcp-server/ - Python MCP server with storage adapters

• packages/homepage/ - Public documentation site (for Phase 2+ launch)

• docs/ - Shared architectural and implementation documentation

Quick Start

For Contributors/Development

Prerequisites:

• Python 3.10+

• Node.js 18+

• npm (comes with Node.js)

Setup:

# 1. Clone the repository
git clone https://github.com/BANCS-Norway/claude_session_coordinator.git
cd claude_session_coordinator

# 2. Install git hooks (automatic linting on commit)
npm install

# 3. Install Python MCP server package
cd packages/mcp-server
pip install -e ".[dev]"

See CONTRIBUTING.md for detailed development guidelines.

For Users (Phase 1 - Development)

cd packages/mcp-server
pip install -e .

Quick Start with Claude Code

1. Install the MCP server:

   cd packages/mcp-server
   pip install -e ".[dev]"

2. Configure Claude Code:

   # Copy the template
   cp .mcp.json.template .mcp.json
   
   # Edit with your paths
   nano .mcp.json

3. Update .mcp.json with your actual paths:

   {
     "mcpServers": {
       "claude-session-coordinator": {
         "command": "/path/to/your/python3",
         "args": [
           "-m",
           "claude_session_coordinator"
         ],
         "env": {},
         "cwd": "/path/to/claude_session_coordinator"
       }
     }
   }

4. Restart Claude Code - the session coordinator will be available automatically!

Features

Storage Adapters

• Local File Adapter (Phase 1) - Simple JSON file storage

• Redis Adapter (Phase 2+) - Cross-machine coordination

• Custom Adapters - Implement your own backend

MCP Tools

• store_data() - Store data in scoped contexts

• retrieve_data() - Retrieve stored data

• list_keys() - Discover available keys in a scope

• list_scopes() - List all scopes with optional filtering

• delete_data() - Remove specific data

MCP Resources

• session://context - Current session state and available instances

• session://state/{id} - Read other sessions' state (coordination)

MCP Prompts

• startup - Guides Claude through sign-on process

• sign-off - Guides proper session release
