Standalone MCP server for jhabit — a habit and quit tracker. Connects to your jhabit instance via API key and exposes tracking tools to MCP clients like Claude Desktop and Claude Code.

Note: jhabit also has a built-in remote MCP server using OAuth 2.1 + Streamable HTTP, for cloud-based MCP clients. This standalone server is for local stdio-based clients.
