WHAT IT DOES

What create_block_slot does on GoHighLevel MCP Server

AI agents use create_block_slot to create or update resources in GoHighLevel MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GoHighLevel MCP Server environment.

RISK

Why create_block_slot is rated Medium

This tool creates a new calendar block entry in the scheduling system, which is a reversible write operation. If misused by an agent, it could block legitimate business hours from accepting bookings, causing operational disruption. However, the impact is recoverable (blocks can be removed), and no financial transactions or irreversible data destruction occurs.

From the tool's definition Tool description states 'Create a blocked time slot' — the verb 'create' combined with the action of writing a calendar blocking rule to persistent storage indicates data creation.
