memory-hub-mcp 0.1.1

Local Memory Hub MCP Server with stdio transport for ZenCoder and MCP clients

Memory Hub MCP Server (UV/UVX)

A local memory hub for AI agents with MCP integration, designed for ZenCoder and other MCP clients using stdio transport.

Quick Start with UVX

Installation & Usage

# Install and run directly with uvx
uvx memory-hub-mcp

# Or install locally first
uv pip install memory-hub-mcp
memory-hub-mcp

For ZenCoder Integration

In ZenCoder's custom MCP server configuration:

Command: uvx memory-hub-mcp
Arguments: (leave empty for default stdio mode)

Development Setup

# Clone and setup
git clone <your-repo>
cd memory-hub
uv venv
source .venv/bin/activate
uv pip install -e .

# Run in development
memory-hub-mcp --log-level DEBUG

Publishing to PyPI

To publish a new version of the package to PyPI:

1. Update the Version: Increment the version number in pyproject.toml. PyPI does not allow re-uploading the same version.

   # pyproject.toml
   [project]
   name = "memory-hub-mcp"
   version = "0.1.2" # Increment this
   

2. Build the Distributions:

   uv build
   

   This command creates the necessary .whl and .tar.gz files in the dist/ directory.

3. Publish with an API Token:

   The recommended way to publish is to use a PyPI API token. You can provide it directly to the command via an environment variable for security.

   # Replace <your_pypi_token> with your actual token
   UV_PUBLISH_TOKEN=<your_pypi_token> uv publish dist/*
   

Available Tools

• add_memory: Store content with hierarchical metadata (app_id, project_id, ticket_id)
• search_memories: Semantic search with keyword enhancement and LLM synthesis
• list_app_ids: List all application IDs
• list_project_ids: List all project IDs
• list_ticket_ids: List all ticket IDs
• health_check: Server health status

Configuration

The server expects:

• Qdrant: Vector database running (see docker-compose.yml)
• LM Studio: For embeddings and chat completions
• Environment: Standard .env configuration

Key File & Directory Locations

• pyproject.toml: Defines project metadata, dependencies, and the memory-hub-mcp script entry point.
• src/memory_hub/: The main Python package source code.
• src/memory_hub/cli.py: The command-line interface logic that launches the server.
• src/memory_hub/mcp_server.py: Core stdio server implementation and tool registration.
• src/memory_hub/core/handlers/: Contains the implementation for each MCP tool (e.g., add_memory, search_memories).
• src/memory_hub/core/services.py: Handles communication with external services like Qdrant and LM Studio.
• src/memory_hub/core/models.py: Pydantic models defining the data structures used throughout the application.
• docker-compose.yml: Defines the Qdrant service dependency.

Architecture

• stdio transport: Direct MCP protocol communication
• No HTTP dependencies: Lightweight, focused on MCP clients
• Hierarchical memory: Flexible app/project/ticket organization
• Hybrid search: Vector similarity + keyword matching + LLM synthesis

Differences from HTTP Version

This UV/UVX version:

• ✅ Uses stdio transport (ZenCoder compatible)
• ✅ No FastAPI dependencies
• ✅ Lightweight packaging
• ✅ Direct MCP protocol
• ❌ No web interface
• ❌ No HTTP endpoints
