MCP Memory Server

A persistent vector memory server for Windsurf, VS Code, and other MCP-compliant editors.

🌟 Philosophy

• Privacy-first, local-first AI memory: Your data stays on your machine.
• No vendor lock-in: Uses open standards and local files.
• Built for MCP: Designed specifically to enhance Windsurf, Cursor, and other MCP-compatible IDEs.

ℹ️ Status (v0.1.0)

Stable:

• ✅ Local MCP memory with Windsurf/Cursor
• ✅ Multi-project isolation
• ✅ Ingestion of Markdown docs

Not stable yet:

• 🚧 Auto-ingest (file watching)
• 🚧 Memory pruning
• 🚧 Remote sync

Note: This server uses MCP stdio transport (not HTTP) to match Windsurf/Cursor’s native MCP integration. Do not try to connect via curl.

🏥 Health Check

To verify the server binary runs correctly:

# From within the virtual environment
python -m mcp_memory.server --help

✅ Quickstart (5-Minute Setup)

1. Clone and Setup

git clone https://github.com/iamjpsharma/MCPServer.git
cd MCPServer/mcp-memory-server

# Create and activate virtual environment
python3 -m venv .venv
source .venv/bin/activate

# Install dependencies
pip install -e .

2. Configure Windsurf / VS Code

Add this to your mcpServers configuration (e.g., ~/.codeium/windsurf/mcp_config.json):

Note: Replace /ABSOLUTE/PATH/TO/... with the actual full path to this directory.

{
  "mcpServers": {
    "memory": {
      "command": "/ABSOLUTE/PATH/TO/mcp-memory-server/.venv/bin/python",
      "args": ["-m", "mcp_memory.server"],
      "env": {
        "MCP_MEMORY_PATH": "/ABSOLUTE/PATH/TO/mcp-memory-server/mcp_memory_data"
      }
    }
  }
}

🚀 Usage

1. Ingestion (Adding Context)

Use the included helper script ingest.sh to add files to a specific project.

# ingest.sh <project_name> <file1> <file2> ...

# Example: Project "Thaama"
./ingest.sh project-thaama \
  docs/architecture.md \
  src/main.py

# Example: Project "OpenClaw"
./ingest.sh project-openclaw \
  README.md \
  CONTRIBUTING.md

💡 Project ID Naming Convention

It is recommended to use a consistent prefix for your project IDs to avoid collisions:

• project-thaama
• project-openclaw
• project-myapp

2. Connect in Editor

Once configured, the following tools will be available to the AI Assistant:

• memory_search(project_id, q): Semantic search for "project-thaama", "project-openclaw", etc.
• memory_add(project_id, id, text): Manual addition of memory fragments.

The AI will effectively have "long-term memory" of the files you ingested.

🛠 Troubleshooting

• "No MCP server found" or Connection errors:

  • Check the output of pwd to ensure your absolute paths in mcp_config.json are 100% correct.
  • Ensure the virtual environment (.venv) is created and dependencies are installed.

• "Wrong project_id used":

  • The AI sometimes guesses the project ID. You can explicitly tell it: "Use project_id 'project-thaama'".

• Embedding Model Downloads:

  • On the first run, the server downloads the all-MiniLM-L6-v2 model (approx 100MB). This may cause a slight delay on the first request.
