Data privacy

  • Anthropic (Claude), only in the non-CI agent step your book highlights and matched notes (retention: per Anthropic's API/data policy)

Prerequisites

  • Claude Desktop, https://claude.ai/download
  • Node 20+ (MCPVault runs via npx)
  • Your highlights pasted into a Books/ note

Steps

  1. 1

    Validate config and scaffold a Books/ highlights note

    CI validates the MCPVault config and drops a sample highlights note in Books/ for the synthesis step to read.

    cat > claude_desktop_config.json <<'EOF'
    { "mcpServers": { "obsidian": { "command": "npx", "args": ["@bitbonsai/mcpvault@latest", "/Users/you/Documents/MyVault"] } } }
    EOF
    node -e 'const c=JSON.parse(require("fs").readFileSync("claude_desktop_config.json","utf8"));const o=c.mcpServers.obsidian;if(o.command==="npx"&&o.args.some(a=>a.indexOf("@bitbonsai/mcpvault")===0)){console.log("config OK: npx -> @bitbonsai/mcpvault")}else{console.log("BAD");process.exit(1)}'
    mkdir -p vault/Books
    printf '%s\n' '# Atomic Habits, highlights' 'Small habits compound over time.' > vault/Books/atomic-habits.md
    test -s vault/Books/atomic-habits.md && echo "books ready: vault/Books/atomic-habits.md"
  2. 2

    File the book (the Claude step, not checked by CI)

    Tell Claude to read Books/atomic-habits.md, search the vault for connected notes, and write Books/atomic-habits-synthesis.md with key ideas, links, project-tied takeaways, and next reads. Uses read_note + search_notes + write_note; runs a model, so CI doesn't run it.
