fast-note-sync-service
High-performance, low-latency note synchronization, online management, and remote REST API service platform.
Fast Note Sync Service is an MCP-compliant server and note synchronization platform built with Go, WebSocket, and React that enables AI clients to manage personal notes and attachments. It provides native Model Context Protocol support through both SSE and StreamableHTTP transports, allowing AI assistants in Cherry Studio, Cursor, Claude Code, and hermes-agent to read, write, and sync notes in real-time. The platform combines an MCP server interface with a web admin panel, REST API, and multi-device synchronization capabilities for Obsidian vaults. Developers can integrate it as an MCP server to give AI assistants persistent memory and note-taking abilities, with all changes automatically synchronized across connected devices via WebSocket.
