ZenMemory MCP Server provides decentralized AI memory infrastructure powered by Model Context Protocol and Solana Agent Kit, enabling you to store and retrieve memory contexts through a simple API with blockchain integration.
Clone the repository and install dependencies:
git clone https://github.com/ZenMemoryAI/zenmemory-mcp-sol.git
cd zenmemory-mcp-sol
npm install
Set up your environment by creating a .env
file with your Solana keypair:
SOLANA_SECRET_KEY=your_base58_encoded_private_key
Run the server using:
npm start
The server will start and listen for incoming connections on the default port.
The MCP Server exposes the following HTTP endpoints:
POST /memory
Request body example:
{
"userId": "user123",
"content": "This is a memory to be stored",
"metadata": {
"tags": ["important", "reminder"]
}
}
GET /memory/:id
Replace :id
with the memory identifier returned when storing a memory.
GET /user/:userId/memories
Replace :userId
with the user's unique identifier to retrieve all their memories.
ZenMemory MCP Server supports:
To configure a specific storage option, update the server configuration in your code or environment variables according to your needs.
To add this MCP server to Claude Code, run this command in your terminal:
claude mcp add-json "zenmemory-mcp-sol" '{"command":"npx","args":["-y","zenmemory-mcp-sol"]}'
See the official Claude Code MCP documentation for more details.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json
file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json
file.
To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".
When you click that button the ~/.cursor/mcp.json
file will be opened and you can add your server like this:
{
"mcpServers": {
"zenmemory-mcp-sol": {
"command": "npx",
"args": [
"-y",
"zenmemory-mcp-sol"
]
}
}
}
To add an MCP server to a project you can create a new .cursor/mcp.json
file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
To add this MCP server to Claude Desktop:

~/.config/Claude/claude_desktop_config.json
2. Add this to your configuration file:
{
"mcpServers": {
"zenmemory-mcp-sol": {
"command": "npx",
"args": [
"-y",
"zenmemory-mcp-sol"
]
}
}
}
3. Restart Claude Desktop for the changes to take effect
