PerSQL

Provisions isolated SQLite databases on demand and exposes them as MCP tools your agent can query directly. Create a fresh database per agent run, per pull request, or per user with a single API call. The SDK includes `db.asTool()` to hand Claude or GPT a scoped database connection, plus branch leasing for sub-agents with roles and TTLs. Useful when you want agents to have their own sandbox for SQL operations without sharing state, or when CI needs schema-only preview databases that auto-expire. Ships with LangGraph checkpointer and OpenAI Agents session adapters. Pay per request and row scanned, not per database.
