create_table · SQLite MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_table does on SQLite MCP Server

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

WHY IT NEEDS A POLICY

Why create_table needs a policy

Creating a table is a reversible write operation—the table can be dropped and is not inherently destructive of existing data. It modifies database schema but does not delete or overwrite data. Severity is medium because uncontrolled table creation could exhaust storage or pollute the schema, but the operation is recoverable.

From the tool's definition Tool name 'create_table' and description '创建新表' (create new table in Chinese) directly indicate creation of a new database table. Sibling tools include 'execute_update' and 'execute_query', confirming this server performs database mutations.

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.
