LogSeqBLOCK
MCP server to interact with LogSeq via its Local HTTP API - enabling AI assistants like Claude to seamlessly read, write, and manage your LogSeq graph.
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
MCP server for LogSeq Connect Claude to your LogSeq knowledge base. Read, create, and manage pages — with optional semantic vector search and DB-mode graph support.
✨ What You Can Do
Transform your LogSeq knowledge base into an AI-powered workspace! This MCP server enables Claude to seamlessly interact with your LogSeq graphs.
🎯 Real-World Examples
📊 Intelligent Knowledge Management
"Analyze all my project notes from the past month and create a status summary" "Find pages mentioning 'machine learning' and create a study roadmap" "Search for incomplete tasks across all my pages"
📝 Automated Content Creation
"Create a new page called 'Today's Standup' with my meeting notes" "Add today's progress update to my existing project timeline page" "Create a weekly review page from my recent notes"
🔍 Smart Research & Analysis
"Compare my notes on React vs Vue and highlight key differences" "Find all references to 'customer feedback' and summarize themes" "Create a knowledge map connecting related topics across pages"
🧠 Semantic Search (optional, requires vector setup)
"Find everything I wrote about burnout, even if I didn't use that word" "What notes relate to my thoughts on deep work?" "Search across my Dutch and English notes for ideas about productivity"
🤝 Meeting & Documentation Workflow
"Read my meeting notes and create individual task pages for each action item" "Get my journal entries from this week and create a summary page" "Search for 'Q4 planning' and organize all related content into a new overview page"
💡 Key Benefits
- Zero Context Switching: Claude works directly with your LogSeq data
- Preserve Your Workflow: No need to export or copy content manually
- Intelligent Organization: AI-powered page creation, linking, and search

Questions
What is the LogSeq MCP server?
MCP server to interact with LogSeq via its Local HTTP API - enabling AI assistants like Claude to seamlessly read, write, and manage your LogSeq graph.
What tools does LogSeq expose?
1 in total: 1 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is LogSeq safe to connect to an agent?
No — not without reading the findings first. The audit graded it D (69/100) and found 2 critical or high issues in the source. Each one is listed on this page with the file and line it is on.
What credentials does LogSeq need?
It reads LOGSEQ_API_TOKEN and MCP_HTTP_AUTH_TOKEN from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does LogSeq run?
It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on PyPI as mcp-logseq.
How current is this page?
The grade is for one exact copy of the source (6c8d8e488d89), read on 2026-10-07. The repository is watched and re-audited when it changes.
