WHAT IT DOES

What hello does on Supabase MCP Server - Self-Hosted Edition

AI agents call hello as a supporting operation in Supabase MCP Server - Self-Hosted Edition workflows.

RISK

Why hello is rated Low

The name and description ('Hello World') suggest this is a simple greeting/test endpoint with no meaningful side effects, data access, or operations. It appears to be a placeholder or connectivity test tool. Description is uninformative, lowering confidence.

From the tool's definition Tool name: 'hello', description: 'Hello World'

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs hello safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Supabase MCP Server - Self-Hosted Edition, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hello, this is the rule to start with:

hello Rate-limited

hello gets a rate cap, and everything else on the server is denied unless you say otherwise.
