Common questions

Is HippoDid MCP Server safe?

It passed 0 of 2 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 7 months ago, and the latest version (1.1.0) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.

What can I use instead?

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

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.

Environment Variables

Variable	Required	Default	Description
`HIPPODID_API_KEY`	Yes	—	Your HippoDid API key
`HIPPODID_CHARACTER_ID`	No	—	Default character UUID for background sync
`HIPPODID_BASE_URL`	No	`https://api.hippodid.com`	API base URL
`MCP_SYNC_INTERVAL`	No	`300`	Background sync interval in seconds

`MCP_AUTO_RECALL`	No	`false`	Disable background hydration (AI handles download)
`MCP_RECALL_CACHE_TTL`	No	`120`	Search result cache TTL in seconds

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.
