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.

Key features:

  • Cross-platform memory — same memories accessible from any MCP client or ChatGPT via OAuth
  • Structured extraction — raw text is automatically parsed into categorized facts with salience scores
  • Temporal decay — memories fade naturally by category (skills are evergreen, events fade in 14 days)
  • Character scoping — each agent/project gets its own memory namespace
  • BYOK AI — bring your own OpenAI, Anthropic, or Gemini key for extraction

Quick Start

1. Get an API Key

Sign up at hippodid.com and create an API key from your dashboard.

2. Download the JAR

Download the latest release from GitHub Releases.

3. Configure Claude Desktop

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "hippodid": {
      "command": "java",
      "args": ["-jar", "/path/to/hippodid-mcp-server-1.1.0.jar"],
      "env": {
        "HIPPODID_API_KEY": "hd_key_your_key_here",
        "HIPPODID_CHARACTER_ID": "your-character-uuid"
      }
    }
  }
}
4. Start Using

Ask Claude to remember things, search memories, sync files, and more.

Architecture

Claude Desktop → stdio (JSON-RPC) → McpServerRunner → HippoDidClient → HTTP → HippoDid REST API

The MCP server uses the hippodid-spring-boot-starter to communicate with the HippoDid REST API over HTTP. All authentication and tenant isolation is handled server-side via Bearer tokens.

Building from Source

Requires Java 21+ and Maven 3.8+.

mvn clean package -DskipTests
java -jar target/hippodid-mcp-server-1.1.0.jar

Versioning

The MCP server version matches the hippodid-spring-boot-starter version. Both must be at the same version for compatibility.
