HippoDid MCP Server
Gives Claude persistent memory that survives across sessions and travels between AI tools. You get structured storage for preferences, decisions, and context via a cloud API, with tools to add memories, search semantically, sync local files, and configure your own OpenAI or Anthropic keys for extraction. HippoDid automatically categorizes facts and applies temporal decay so skills stick around while events fade. The Java server connects over stdio and talks to the HippoDid REST API. Useful when you're switching between Claude Desktop, Cursor, and ChatGPT but want the agent to remember what you told it last week without re-explaining your project setup every time.

HippoDid MCP Server — persistent cloud memory for AI agents
HippoDid MCP Server
Persistent, portable memory for AI agents. Your AI forgets everything between sessions. HippoDid remembers.
HippoDid MCP Server
MCP (Model Context Protocol) server for HippoDid — connects Claude Code, Claude Desktop, ChatGPT, Gemini CLI, Codex CLI, Cursor, and any MCP-compatible client to persistent AI character memory.
What is HippoDid?
HippoDid is a cloud memory infrastructure for AI agents. It stores structured memories (preferences, decisions, skills, relationships) in a searchable database and retrieves them across sessions, tools, and AI providers. Write a memory in Claude Code, recall it in ChatGPT. Switch from Cursor to Gemini — your agent's memory travels with it.
