WHAT IT DOES

What createWebhook does on AMOCA Solana MCP Server

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

WHY IT NEEDS A POLICY

Why createWebhook needs a policy

This tool creates a new webhook configuration, which is a reversible write operation. It establishes a monitoring endpoint but does not execute transactions, move funds, or permanently delete data. The severity is medium because misconfigured webhooks could cause monitoring of unintended addresses or trigger unintended notifications, with moderate blast radius if an agent creates malicious webhooks at scale.

From the tool's definition Tool name 'createWebhook' and description 'Create a new webhook for address activity monitoring' indicate a data creation operation that establishes a persistent monitoring configuration.
