Logseq MCP Server

Let AI read and write your Logseq graph directly via MCP

한국어 README

Talk to Claude and say "add this to today's journal", "find what I did last week", "show me all pages linked to this one" - and it just works.

Why This?

Problem: Logseq is a great PKM tool, but integrating with AI assistants requires constant copy-pasting.

Solution: With this MCP server:

• Claude directly writes to your journal (no copy-paste)
• Search and summarize past entries (maintain context)
• Navigate connections between pages (backlinks, graph)
• Auto-generate daily journals with templates

You: "Summarize today's meeting notes and add them to my journal"
Claude: [writes directly to Logseq via logseq-mcp]
        "Done! Added to today's journal. Anything else?"

Is This For You?

Good fit if you...

• Use Logseq as your primary PKM
• Use Claude Code or Claude Desktop regularly
• Want to delegate note management to AI
• Use local file-based Logseq (not Logseq Sync)

Not for you if...

• Using Logseq Sync (requires local file access)
• Obsidian user (different MCP server needed)
• Have sensitive info in notes and uncomfortable with AI access
• Use org-mode instead of Markdown (not yet supported)

Logseq Graph Structure

your-graph/
  journals/     # Daily journals (2024_01_15.md format)
  pages/        # Regular pages
  logseq/       # Logseq settings
  whiteboards/  # Whiteboards

Security

• Path traversal protection (graph-only access)
• Symlink/hardlink attack prevention
• Input validation and sanitization
• DoS protection (content size limits)
• Error message sanitization

Troubleshooting

"LOGSEQ_GRAPH_PATH environment variable is required"

Set LOGSEQ_GRAPH_PATH in your configuration file.

MCP server not recognized by Claude

1. Restart Claude Code/Desktop
2. Verify path is absolute (/Users/... format)
3. Ensure npm run build was executed

Pages not showing up

• Check if .md files exist in journals/ or pages/
• Verify you're using local graph (not Logseq Sync)

org-mode files not reading

Currently Markdown only. org-mode support planned for future.

Korean-Specific Features

This project includes features optimized for Korean users:

Daily Automation (Optional)

Auto-generate daily journal with weather (Korea only - uses Naver Weather) and diary template.

1. Copy and edit plist file:

cp com.logseq.daily-automation.plist.example ~/Library/LaunchAgents/com.logseq.daily-automation.plist
# Edit the file to replace /path/to/ with your actual paths

2. Load launchd agent:

launchctl load ~/Library/LaunchAgents/com.logseq.daily-automation.plist

3. Test manually:

./run-daily-automation.sh

Generated template structure:

- [[일기]]
  - [[날씨]]
    - {weather info}
  - [[오늘의 일기]]
    - [[행복도]]
      - [[오늘의 행복]]
    - [[오늘의 컨디션]]
      - [[수면]]
        - 취침:
        - 기상:
        - 질: /5
    - [[오늘의 생각]]
  - [[Tasks]]
    - TODO
    - [[오늘 잘 해낸 일]]
  - [[TIL]]

See Korean README for more details.

Cultural Content Structure

add_book, add_movie, add_exhibition tools use Korean wikilink structure ([[문화]]). Customize the templates in src/index.ts for your language.
