Heavy backend for Claude Skills MCP server with vector search (Streamable HTTP)

Claude Skills MCP Backend

Heavy backend server for Claude Skills MCP system with vector search capabilities.

Overview

This is the backend component of the Claude Skills MCP system. It provides:

• Vector-based semantic search using sentence-transformers
• Skill indexing and retrieval
• MCP protocol via Streamable HTTP transport
• Background skill loading from GitHub and local sources

Note: This package is typically auto-installed by the frontend (claude-skills-mcp). You only need to install it manually for:

• Remote deployment (hosting your own backend)
• Development and testing
• Standalone usage without the frontend proxy

# Via uv (recommended)
uv tool install claude-skills-mcp-backend
