# MemoryPlugin > MemoryPlugin gives AI tools one shared, permanent memory. Users save memories, sync chat history, and upload files once; every connected AI tool (21+ of them, ChatGPT, Claude, Gemini, and Cursor included) can recall them. Integration surfaces: a browser extension, a remote MCP server, and a desktop sync app. Key facts: the remote MCP server lives at https://www.memoryplugin.com/api/mcp/mcp (streamable HTTP; SSE at https://www.memoryplugin.com/api/mcp/sse); authentication is OAuth 2.1 with dynamic client registration, no API keys. The server exposes 14 tools across memories, buckets, chat history, and files. ## Docs - [MCP server documentation](https://www.memoryplugin.com/mcp): Endpoints, OAuth flow, scopes, and a reference for every MCP tool - [MCP server reference (full text)](https://www.memoryplugin.com/llms-full.txt): The complete MCP tool reference as plain Markdown - [Help center](https://help.memoryplugin.com): Setup guides and troubleshooting for every supported platform ## Product - [Homepage](https://www.memoryplugin.com/): What MemoryPlugin is and how the shared memory works - [Memory features](https://www.memoryplugin.com/features/memory): Buckets, Smart Memory, and how memories stay clean - [Chat history](https://www.memoryplugin.com/features/chat-history): Sync and search past AI conversations from any tool - [Supported platforms](https://www.memoryplugin.com/platforms): Per-tool setup for the 21+ supported AI tools - [Pricing](https://www.memoryplugin.com/#pricing): Plans and the 7-day free trial ## Free tools - [AI chat viewer](https://www.memoryplugin.com/tools/ai-chat-viewer): Browse and search chat exports in the browser - [ChatGPT to Markdown](https://www.memoryplugin.com/tools/chatgpt-to-markdown): Convert a ChatGPT export to Markdown files - [AI chat to Markdown](https://www.memoryplugin.com/tools/ai-chat-to-markdown): Auto-detects ChatGPT, Claude, Grok, and TypingMind exports ## Optional - [AI memory wiki](https://www.memoryplugin.com/wiki/): Explainers on AI memory concepts - [Alternatives comparisons](https://www.memoryplugin.com/alternatives/supermemory): How MemoryPlugin compares to other memory tools - [Vision](https://www.memoryplugin.com/vision): Why one memory across every AI
