create_table · Mcp Sqlite Manager MCP: Risk & Policy

WHAT IT DOES

What create_table does on Mcp Sqlite Manager

AI agents use create_table to create or update resources in Mcp Sqlite Manager — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Sqlite Manager environment.

WHY IT NEEDS A POLICY

Why create_table needs a policy

Creating a table is a Write operation: it modifies the database schema by adding a new table structure, but this action is reversible (the table can be dropped). While it has potential side effects if created in a production database or with unintended schema, it does not irreversibly destroy data (Destructive) or execute arbitrary computational operations (Execute).

From the tool's definition Tool description states 'Create a new table in the SQLite database using raw SQL' — this is a reversible data structure modification operation.

Verdict

create_table Rate-limited

create_table stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
