BoltSchema - Turn any database into a hosted MCP server
by•
Connecting LLMs and AI agents to real-time production data shouldn't mean writing endless boilerplate middleware. BoltSchema automatically converts your PostgreSQL into secure, production-ready, and hosted Model Context Protocol (MCP) servers. Save days of engineering time, handle JSON-RPC schemas automatically, and let your AI securely query the exact data context it needs in under 60 seconds.

Hey Product Hunt 👋 Maker here.
I built BoltSchemabecause connecting an AI assistant to a real database is still way too painful — you write a custom MCP server, wrestle with config files, and end up handing your AI write access to production data and just hoping it behaves.
BoltSchema fixes that. Paste a Postgres connection string → get a hosted MCP endpoint in ~60 seconds. Point Claude Desktop, Cursor, or Continue at it and your assistant can explore schemas and run queries safely.
The whole thing is built around safety by default:
🔒 Credentials encrypted at rest with AES-256-GCM
🛡️ Every query runs inside a Postgres READ ONLY transaction — even if something slips past the SQL guard, the database itself refuses the write
🚫 A keyword guard that strips comments/string literals before blocking DROP, DELETE, INSERT, and friends
Don't want to connect your own DB yet? There's a zero-trust live sandbox — one click seeds a realistic e-commerce database and hands you a public token you can drop straight into Claude Desktop. No signup needed.
This is an early launch and I'd genuinely love your feedback — especially: which database would you want next after Postgres? (MySQL, Mongo, Snowflake…?)
I'll be around all day answering questions. 🙏
