How would you restrict the MCP to only allow predefined safe SQL operations?

Restricting the MCP to predefined safe SQL operations involves a combination of design patterns and tooling. First, create a catalog of allowed SQL templates (e.g., SELECT * FROM table WHERE id = ?) and store them in a secure repository. The MCP should reference this catalog rather than building queries on the fly. Use parameterized statements to avoid injection. Second, enforce database roles that grant the MCP only read‑only or limited write permissions on specific schemas. Third, implement a query‑validation service that parses incoming SQL, checks it against the whitelist, and rejects any disallowed clauses. Fourth, consider using a database proxy that intercepts queries, applies the whitelist, and logs all activity. Finally, monitor the MCP’s activity with audit logs and set up alerts for any attempts to execute non‑whitelisted statements. This layered strategy ensures the MCP can perform its required tasks while preventing accidental or malicious data manipulation.
