MCP server SharedMemory

@sharedmemory/mcp-server

Model Context Protocol server for SharedMemory. Gives Claude Code, Claude Desktop, Cursor, VS Code Copilot, and other MCP-compatible tools persistent memory.

Quick Install (Recommended)

The fastest way to set up SharedMemory — one command, no JSON editing:

# Interactive — picks your client, asks for your API key
npx -y @sharedmemory/mcp-server install

# Or specify everything inline
npx -y @sharedmemory/mcp-server install --cursor --api-key sm_live_... --volume your-volume-id

# Install for all supported clients at once
npx -y @sharedmemory/mcp-server install --all --api-key sm_live_...

Supported clients: --claude-code, --claude, --cursor, --vscode, --windsurf, --all

Manual Setup

If you prefer to edit config files yourself:

Claude Code

One command:

claude mcp add sharedmemory -- npx -y @sharedmemory/mcp-server

Or with env vars:

claude mcp add --env SHAREDMEMORY_API_KEY=sm_live_... \
  --env SHAREDMEMORY_VOLUME_ID=your-volume-id \
  sharedmemory -- npx -y @sharedmemory/mcp-server

Or create .mcp.json in your project root to share with your team:

{
  "mcpServers": {
    "sharedmemory": {
      "command": "npx",
      "args": ["-y", "@sharedmemory/mcp-server"],
      "env": {
        "SHAREDMEMORY_API_KEY": "${SHAREDMEMORY_API_KEY}",
        "SHAREDMEMORY_API_URL": "https://api.sharedmemory.ai",
        "SHAREDMEMORY_VOLUME_ID": "${SHAREDMEMORY_VOLUME_ID}"
      }
    }
  }
}

Tip: Copy the included CLAUDE.md into your project root to teach Claude Code when and how to use SharedMemory proactively.

Claude Desktop

~/Library/Application Support/Claude/claude_desktop_config.json:

{

        "SHAREDMEMORY_VOLUME_ID": "your-volume-id"
      }
    }
  }
}

Cursor

.cursor/mcp.json in your project root:

{
  "mcpServers": {
    "sharedmemory": {
      "command": "npx",
      "args": ["-y", "@sharedmemory/mcp-server"],
      "env": {
        "SHAREDMEMORY_API_KEY": "sm_live_...",
        "SHAREDMEMORY_API_URL": "https://api.sharedmemory.ai",
        "SHAREDMEMORY_VOLUME_ID": "your-volume-id"
      }
    }
  }
}

VS Code Copilot

.vscode/mcp.json:

{
  "servers": {
    "sharedmemory": {
      "command": "npx",
      "args": ["-y", "@sharedmemory/mcp-server"],
      "env": {
        "SHAREDMEMORY_API_KEY": "sm_live_...",
        "SHAREDMEMORY_API_URL": "https://api.sharedmemory.ai",
        "SHAREDMEMORY_VOLUME_ID": "your-volume-id"
      }
    }
  }
}

Windsurf

~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "sharedmemory": {
      "command": "npx",
      "args": ["-y", "@sharedmemory/mcp-server"],
      "env": {
        "SHAREDMEMORY_API_KEY": "sm_live_...",
        "SHAREDMEMORY_API_URL": "https://api.sharedmemory.ai",
        "SHAREDMEMORY_VOLUME_ID": "your-volume-id"
      }
    }
  }
}
