OpenMemory MCP Bridge

A Model Context Protocol (MCP) bridge for OpenMemory SSE endpoints that provides a direct connection between MCP clients (like Claude Desktop, Cursor, etc.) and OpenMemory servers without requiring intermediaries like supergateway.

Features

• Direct Connection: Connects directly to OpenMemory SSE endpoints without intermediaries
• Dynamic Parameters: Supports dynamic client and user ID parameters
• MCP Protocol: Implements the MCP protocol for seamless integration with MCP clients
• Tool Support: Provides access to OpenMemory's memory management tools
• CLI Interface: Easy-to-use command-line interface

Installation

No installation required! Use uvx to run directly:

uvx openmemory-mcp-bridge --sse http://localhost:8765/mcp/{client}/sse/{userid}

Usage

Basic Usage (Similar to supergateway)

openmemory-mcp-bridge --sse http://localhost:8765/mcp/claude/sse/moot

Using Explicit Parameters

openmemory-mcp-bridge --base-url http://localhost:8765 --client claude --user-id userid

Command Line Options

• --sse URL: SSE endpoint URL (e.g., http://localhost:8765/mcp/claude/sse/moot)
• --url URL: Alternative way to specify the URL
• --client NAME: Client name (e.g., claude, cursor) - explicit CLI args take precedence over URL parsing
• --user-id ID: User ID for the session - explicit CLI args take precedence over URL parsing
• --base-url URL: Base URL for OpenMemory API (e.g., http://localhost:8765)
• --verbose, -v: Enable verbose logging
• --help: Show help message

Note: Explicit CLI arguments (--client, --user-id) take precedence over values parsed from the SSE URL. This allows you to override the client and user ID even when using the --sse option.

Integration with MCP Clients

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "openmemory": {
      "command": "uvx",
      "args": [
        "openmemory-mcp-bridge",
        "--sse",
        "http://localhost:8765/mcp/claude/sse/moot"
      ]
    }
  }
}

Cursor

Add to your ~/.cursor/mcp.json:

{
  "mcpServers": {
    "openmemory": {
      "command": "uvx",
      "args": [
        "openmemory-mcp-bridge",
        "--sse",
        "http://localhost:8765/mcp/cursor/sse/moot"
      ]
    }
  }
}

Using Explicit Parameters

You can also use explicit parameters instead of the SSE URL:

{
  "mcpServers": {
    "openmemory": {
      "command": "uvx",
      "args": [
        "openmemory-mcp-bridge",
        "--base-url",
        "http://localhost:8765",
        "--client",
        "claude",
        "--user-id",
        "moot"
      ]
    }
  }
}

Available Tools

The bridge provides comprehensive access to OpenMemory's API through these tools:

Core Memory Operations

• add_memories: Add new memories to the user's memory store
• get_memories: Retrieve memories based on a search query
• delete_memories: Delete specific memories by ID
• delete_all_memories: Delete all memories for a user
• get_memory_history: Get the history of memory operations

Advanced Memory Management

• get_memory_by_id: Get a specific memory by its ID
• update_memory: Update the content of a specific memory
• archive_memories: Archive memories (hidden from normal searches but not deleted)
• get_related_memories: Get memories related to a specific memory
• search_memories: Advanced search with filtering, sorting, and date ranges

Organization & Discovery

• get_categories: Get all available memory categories for the user
• get_user_stats: Get user statistics including total memories and apps
• list_apps: List all apps associated with the user

URL Format

The SSE endpoint URL should follow this pattern:

http://localhost:8765/mcp/{client}/sse/{user_id}

Where:

• {client}: The client name (e.g., claude, cursor)
• {user_id}: The user identifier (e.g., moot)

Why Use This Instead of Supergateway?

• Direct Connection: No intermediary proxy reducing potential points of failure
• OpenMemory Specific: Optimized for OpenMemory's API endpoints
• Better Error Handling: Provides detailed error messages and logging
• Flexible Configuration: Multiple ways to specify connection parameters
• Maintained: Actively maintained as part of the OpenMemory ecosystem
• Comprehensive API Coverage: Supports all OpenMemory API endpoints (13 tools total)

API Coverage

This bridge provides complete coverage of the OpenMemory API:

✅ Memory Operations (/api/v1/memories/)

• Create, read, update, delete memories
• Advanced filtering and search
• Archive functionality
• Related memory discovery
• Category management

✅ App Management (/api/v1/apps/)

• List and filter apps
• App status management

✅ User Statistics (/api/v1/stats/)

• Memory and app statistics
• Usage analytics

🔄 Example Usage

// Add multiple memories
add_memories({"memories": ["User prefers dark mode", "Lives in San Francisco"]})

// Search with advanced filters
search_memories({
  "query": "preferences",
  "categories": ["user", "settings"],
  "from_date": 1704067200,
  "sort_by": "created_at",
  "sort_direction": "desc",
  "limit": 10
})

// Get related memories
get_related_memories({"memory_id": "uuid-here", "limit": 5})

// Archive old memories
archive_memories({"memory_ids": ["uuid1", "uuid2"]})
