data-ai MCP Server
Persistent local memory layer for AI. ArcRift uses a extension and a native MCP server to sync context and decisions from your browser chats (Claude, ChatGPT, DeepSeek) straight to your local IDE agents (Cursor, Claude Code, Windsurf) powered by a local SQLite knowledge graph.

ArcRift
What it does
Retrieves the top-N most relevant memory chunks for a prompt, scoped to a project. Includes knowledge graph facts.
Saves text or a transcript to ArcRift Memory. Auto-creates the project if it does not exist. Triggers full background indexing.
Cross-project global search. Useful for finding decisions made in a different project that apply to the current one.
Lists all saved projects with metadata — chunk count, triple count, last updated.
Returns a structured knowledge graph summary for a project as readable markdown.
Matches a folder path against saved project names. Lets the AI agent auto-detect which project it is working on from the CWD.
Surgically removes facts or chunks matching a description. Corrects outdated information without wiping an entire project.

--- ## What's New in v1.6.3 This release brings full cross-browser support to ArcRift and patches a critical context injection bug. - **Mozilla Firefox Support**: ArcRift is now fully compatible with Firefox! The extension build pipeline generates independent Chrome and Firefox packages, and we have fully automated the Mozilla Add-ons signing pipeline so signed `.xpi` extensions are attached to every release. - **RAG Hallucination Fix**: We caught a bug where out-of-context chats were injecting irrelevant project memory because the vector DB returned the top closest matches no matter how semantically distant they actually were. The retrieval pipeline now enforces a strict 50% relevance threshold. *(Note: If you were testing `v1.6.1` locally, all core desktop app updates remain the same in this release).* See [CHANGELOG.md](CHANGELOG.md) for the full history. --- ## Documentation
