Allows GitHub Copilot in VS Code to read and write project context, enabling continuity across different LLM agents.
Allows OpenAI Codex CLI to share project memory, so it can resume work where other LLMs left off.
This server does not currently have a deployable release on Glama. Follow the repository's setup instructions to install and configure it for your MCP client, including any required credentials and local dependencies.
MCP server that acts as a shared memory hub across multiple LLMs (Claude, Gemini, Copilot, Codex). Any agent entering a project immediately understands its architecture, patterns, and decisions — and can pick up exactly where the previous LLM left off.

| Initialize or retrieve a project |
| Save architecture overview and tech stack |
| Full project overview — perfect as first call |
| Save working state before handing off |
| Retrieve what the previous LLM was doing |
| List all saved sessions |
| Save reusable code patterns (JWT, FCM, etc.) |
| Retrieve patterns by category/language |
| Save an ADR (why a decision was made) |

No install needed. Just add the config below to your tool and it runs automatically via bunx.

"env": { "DB_PATH": "/Users/you/handoff.db" }
