I built a read-only Postgres MCP server so I could point Claude at prod without fear
A developer has created BoltSchema, a read-only interface for PostgreSQL databases designed to allow AI models like Claude to query data without the risk of accidental modification. The system employs multiple layers of defense, including read-only transactions, a sophisticated SQL guard that strips comments and string literals before checking for forbidden keywords, encrypted connection strings, and query result limits. This setup enables AI assistants to safely access and query database schemas and execute read-only SQL commands, with a zero-trust sandbox available for testing. AI
IMPACT Enables safer integration of AI assistants with sensitive production databases, reducing risks of accidental data modification.
