+# PyPI Query MCP Server
+
+A Model Context Protocol (MCP) server for querying PyPI package information, dependencies, and compatibility checking.
+
+## Features
+
+- 📦 Query PyPI package information (name, version, description, dependencies)
+- 🐍 Python version compatibility checking
+- 🔍 Dependency analysis and resolution
+- 🏢 Private PyPI repository support
+- ⚡ Fast async operations with caching
+- 🛠️ Easy integration with MCP clients
+
+## Quick Start
+
+### Installation
+
+```bash
+# Install from PyPI (coming soon)
+pip install pypi-query-mcp-server
+
+# Or install from source
+git clone https://github.com/loonghao/pypi-query-mcp-server.git
+cd pypi-query-mcp-server
+poetry install
+```
+
+### Usage
+
+```bash
+# Start the MCP server
+pypi-query-mcp
+
+# Or run directly with Python
+python -m pypi_query_mcp.server
+```
+
+### Available MCP Tools
+
+The server provides the following MCP tools:
+
+1. **get_package_info** - Get comprehensive package information
+2. **get_package_versions** - List all available versions for a package
+3. **get_package_dependencies** - Analyze package dependencies
+4. **check_package_python_compatibility** - Check Python version compatibility
+5. **get_package_compatible_python_versions** - Get all compatible Python versions
+
+### Example Usage with MCP Client
+
+```python
+# Example: Check if Django is compatible with Python 3.9
+result = await mcp_client.call_tool("check_package_python_compatibility", {
+    "package_name": "django",
+    "target_python_version": "3.9"
+})
+
+# Example: Get package information
+info = await mcp_client.call_tool("get_package_info", {
+    "package_name": "requests"
+})
+```
+
+## Development Status
+
+🎉 **Core functionality implemented and ready for use!**
+
+Current implementation status:
+- ✅ Basic project structure
+- ✅ PyPI API client with caching
+- ✅ MCP tools implementation (package info, versions, dependencies)
+- ✅ Python version compatibility checking
+- ✅ CI/CD pipeline with multi-platform testing
+- ⏳ Private repository support (planned)
+- ⏳ Advanced dependency analysis (planned)
