MCP server for LogSeq
MCP server to interact with LogSeq via its API. Enables Claude to read, create, and manage LogSeq pages through a comprehensive set of tools.
✨ 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"
🤝 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
- Enhanced Productivity: Automate repetitive knowledge work
🚀 Quick Start
Step 1: Enable LogSeq API
- Settings → Features → Check "Enable HTTP APIs server"
- Click the API button (🔌) in LogSeq → "Start server"
- Generate API token: API panel → "Authorization tokens" → Create new
Step 2: Add to Claude (No Installation Required!)
Claude Code
claude mcp add mcp-logseq \
--env LOGSEQ_API_TOKEN=your_token_here \
--env LOGSEQ_API_URL=http://localhost:12315 \
-- uv run --with mcp-logseq mcp-logseq
Claude Desktop
Add to your config file (Settings → Developer → Edit Config
):
{
"mcpServers": {
"mcp-logseq": {
"command": "uv",
"args": ["run", "--with", "mcp-logseq", "mcp-logseq"],
"env": {
"LOGSEQ_API_TOKEN": "your_token_here",
"LOGSEQ_API_URL": "http://localhost:12315"
}
}
}
}
Step 3: Start Using!
"Please help me organize my LogSeq notes. Show me what pages I have."
🛠️ Available Tools
The server provides 6 comprehensive tools:
Tool | Purpose | Example Use |

⚙️ Prerequisites
LogSeq Setup
- LogSeq installed and running
- HTTP APIs server enabled (Settings → Features)
- API server started (🔌 button → "Start server")
- API token generated (API panel → Authorization tokens)
System Requirements
- uv Python package manager
- MCP-compatible client (Claude Code, Claude Desktop, etc.)
🔧 Configuration
Environment Variables
LOGSEQ_API_TOKEN
(required): Your LogSeq API tokenLOGSEQ_API_URL
(optional): Server URL (default:http://localhost:12315
)
Alternative Setup Methods
Using .env file
# .env
LOGSEQ_API_TOKEN=your_token_here
LOGSEQ_API_URL=http://localhost:12315
System environment variables
export LOGSEQ_API_TOKEN=your_token_here
export LOGSEQ_API_URL=http://localhost:12315
🔍 Verification & Testing
Test LogSeq Connection
uv run --with mcp-logseq python -c "
from mcp_logseq.logseq import LogSeq
api = LogSeq(api_key='your_token')
print(f'Connected! Found {len(api.list_pages())} pages')
"
Verify MCP Registration
claude mcp list # Should show mcp-logseq
Debug with MCP Inspector
npx @modelcontextprotocol/inspector uv run --with mcp-logseq mcp-logseq
🐛 Troubleshooting
Common Issues
"LOGSEQ_API_TOKEN environment variable required"
- ✅ Enable HTTP APIs in Settings → Features
- ✅ Click 🔌 button → "Start server" in LogSeq
- ✅ Generate token in API panel → Authorization tokens
- ✅ Verify token in your configuration
"spawn uv ENOENT" (Claude Desktop)
Claude Desktop can't find uv
. Use the full path:
which uv # Find your uv location
Update config with full path:
{
"mcpServers": {
"mcp-logseq": {
"command": "/Users/username/.local/bin/uv",
"args": ["run", "--with", "mcp-logseq", "mcp-logseq"],
"env": { "LOGSEQ_API_TOKEN": "your_token_here" }
}
}
}
Common uv locations:
- Curl install:
~/.local/bin/uv
- Homebrew:
/opt/homebrew/bin/uv
- Pip install: Check with
which uv
Connection Issues
- ✅ Confirm LogSeq is running
- ✅ Verify API server is started (not just enabled)
- ✅ Check port 12315 is accessible
- ✅ Test with verification command above
