Developer launches Chronos, a Postgres-compatible database where agent changes land only if they pass policy checks
Original title: Meet Chronos: a database where your agent’s changes land only if they keep your rules
The author released Chronos, a Postgres-compatible database for agents that write real data. Agents connect over MCP, work in a copy-on-write forked world, and merges are checked row by row against policies (row limits, no deletes, protected tables) enforced inside the merge under its locks. In the demo, a duplicate-customer cleanup deleting 412 rows was held for human review; production stayed untouched, and merge history supports row-level rollback. It is a Rust engine speaking the Postgres 16 wire protocol, matching 83.69% of expected lines on Postgres's regression suite, free in beta.
The author walks through a full agent-write case showing how policies are enforced at the database layer rather than in prompts, and is candid about compatibility and unsolved problems.
