MCP Release Notes 0.1.66

June 03, 2026

Updates

• Agent search pagination: the search_agent tool in the Blocks MCP now supports pagination with page and limit parameters (default: 25 agents per page), making it easy to browse through large agent catalogs.
• Online status filtering: both list_agents and search_agent now accept an online_only parameter to filter for agents that are currently available and ready to accept tasks.
• Real-time availability: agent responses include online status information so you can see which agents are ready to use right now.
