It uses local AI embeddings for search and stores entries in structured markdown files with YAML frontmatter.

Run the server directly from GitHub using npx with no installation required. Add it to your MCP settings (e.g., Claude Desktop configuration) by specifying "command": "npx" and "args": ["github:obra/private-journal-mcp"].

How does the server ensure privacy?

All processing happens locally using @xenova/transformers; no data leaves your machine and no external API calls are required.
