WHAT IT DOES

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

AI agents invoke auto_create_indexes to trigger actions in Supabase MCP Server - Self-Hosted Edition. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why auto_create_indexes is rated High

The tool name suggests it automatically creates database indexes, which is a schema-modifying operation. Creating indexes can have significant performance and storage implications, and 'auto' implies it may do so without explicit per-index confirmation. This is most analogous to a Write/Execute operation (DDL schema modification). With no description to confirm behavior, confidence is reduced.

From the tool's definition Tool name: auto_create_indexes; description is empty.

RECOMMENDED RULE

The rule that runs auto_create_indexes safely

auto_create_indexes Rate-limited

auto_create_indexes stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
