Titan

You can run and connect to a Titan-based MCP server that remembers context across conversations, enabling three-tier memory, continuous learning, and sequence-aware recall to deliver more personalized interactions over time.

How to use

You will install the MCP Titan server, start it, and then connect any MCP client (Cursor, Claude Desktop, or your own interface) to store, recall, and learn from memories. Use the server to persist user context, recall relevant past details during chats, and progressively improve responses through online learning. Start the server, initialize its memory and learner, and then issue store_memory and recall requests through your MCP client to keep track of what the user discussed, what should be remembered long term, and what should be kept in archive storage.

How to install

Prerequisites: Node.js 22 or newer, and npm, bun, or another compatible package manager.

1. Install the MCP Titan package using your preferred package manager.

# Install via npm
npm install @henryhawke/mcp-titan

# Or via bun
bun add @henryhawke/mcp-titan

2. Start the HOPE/MCP Titan server from the command line.

npx @henryhawke/mcp-titan

3. Verify the server creates a memory storage directory and begins listening for MCP tool calls.

# The server will initialize storage at ~/.hope_memory and start accepting MCP commands.
