Session 35 - MCP Session Management System Refactor

Fix session tracking architecture - consolidate to single source of truth

Session 35: MCP Session Management System Refactor

Overview

Major refactor of the MCP session management system to address critical architectural issues:

Multiple sources of truth causing inconsistencies
Session numbers not auto-incrementing
Session state in .cursor/mcp-config.json (should be config only)
Missing session manifests (session-33.json didn't exist)
Concurrent session support issues

Session ID: editor2-35.1 Workspace: editor2 Platform: Cursor

Progress

Completed

✅ Created session-35.json manifest
✅ Updated history.json as source of truth
✅ Updated active.json cache
✅ Updated sessionID.json
✅ Removed session state writing from syncSessionToAllLocations() in MCP
✅ Removed session state writing from session-manager.js

Pending

Add auto-session creation to preflight
Implement file locking for concurrent access
Clean up schema version inconsistencies
Add automatic session number increment detection

Key Changes

1. Session State No Longer Written to mcp-config.json

Before: MCP and session-manager wrote session state to .cursor/mcp-config.json

After: Session state is managed ONLY via:

sessions/sessions-history/{workspace}/history.json - SOURCE OF TRUTH
sessions/sessions-history/{workspace}/active.json - Workspace cache
sessions/sessionID.json - Legacy support

2. File Changes

File	Change
`MCP/mcp-development-ai/src/storage/docs-data-integration.ts`	Removed mcp-config.json sync
`tools/scripts/database/session-manager.js`	Removed mcp-config.json sync
`sessions/sessions-history/editor2/session-35.json`	Created
`sessions/sessions-history/editor2/history.json`	Updated to session 35
`sessions/sessions-history/editor2/active.json`	Updated to session 35

Architecture Notes

Single Source of Truth

sessions/
└── sessions-history/
    └── {workspace}/
        └── history.json        ← ONLY source of truth

Everything else is derived/cached from history.json

Recommended Flow

MCP reads history.json directly
On write, only update history.json
Cache files regenerated lazily on read
Manifests created on first decision, archived on complete
