The MCP server now intelligently handles large datasets that would exceed Claude's token limits:
All list tools now support cursor-based pagination:
# First request
limitless_list_lifelogs_by_date(date="2025-07-24", limit=10)
# Returns: 10 items + cursor
# Next page
limitless_list_lifelogs_by_date(date="2025-07-24", limit=10, cursor="next_page_cursor")
For complete data without manual pagination:
limitless_get_full_transcript(date="2025-07-24", format="transcript_only")
Formats available:
-
summary: Key information only (default) -
full: Complete data including all fields -
transcript_only: Just the transcript text

This message comes from Claude Desktop's UI when responses are too long or the conversation context is filling up. It's NOT related to:
- The MCP server functionality
- Your Claude account tier (free/paid)
- Limitless API limits
Solution: Start a new conversation or ask for shorter responses.
This happens when non-JSON data is sent to the server. MCP servers use JSON-RPC over stdio, not HTTP.
Common mistake: Trying to connect with HTTP clients, browsers, or curl. Solution: Use Claude Desktop or a proper MCP client.
MCP servers are NOT HTTP servers. They communicate via JSON-RPC over stdin/stdout.
Wrong: curl http://localhost:8008
Right: Configure in Claude Desktop's MCP settings
As of March 2025, the Limitless API primarily surfaces data from the Limitless Pendant. Ensure:
- Your Pendant is actively recording
- You have recent conversation data
- Your API key has proper permissions
What MCP servers ARE:
- JSON-RPC services that communicate over stdio
- Designed for Claude Desktop and MCP-compatible clients
- Tools that extend AI assistant capabilities
What MCP servers are NOT:
- HTTP/REST APIs
- Web servers
- Browser-accessible services
- Standalone applications with UIs
If you need HTTP access to Limitless data:
- Use the Limitless API directly
- Create a separate HTTP wrapper service
- Use the official Limitless web interface
