Ghost.build gives Claude a database
- Ghost.build is pitching itself as a Postgres database for agents, with Claude Code able to create, fork, query, pause, and delete databases through MCP tools. - The free tier advertises 100 compute hours a month, 1 terabyte of storage, and unlimited databases and forks inside those limits. - The product turns database state into something agents can branch and discard like code. (ghost.build)
A database is where an app keeps its memory: users, orders, messages, and every change made over time. Ghost is selling that memory to agents as something they can create, fork, and throw away on command. (ghost.build) Ghost says Claude Code can connect through its Model Context Protocol server and then manage a Postgres database with tools like `ghost_create`, `ghost_fork`, `ghost_sql`, and `ghost_schema`. Its docs also list support for Cursor, Windsurf, Codex, Gemini, and Visual Studio Code. (ghost.build) The pitch is simple: let the model get its own database instead of pasting SQL into a chat window or wiring up credentials by hand. Ghost’s quick start says a user logs in with GitHub, runs `ghost mcp install`, creates a database, and starts working from there. (ghost.build) The part that stands out is forking. Ghost’s learn page says a fork copies schema and data, keeps the original untouched, and can be merged back later, turning database work into something closer to a Git branch. (ghost.build) That changes how an agent can test risky ideas. Ghost says an agent can work on an isolated copy of production, make schema changes, add tables, or even drop tables, while the original database stays intact. (ghost.build 1) (ghost.build 2) The company is also leaning hard on price certainty. Its homepage and docs advertise 100 compute hours per month, 1 terabyte of storage, and unlimited databases and forks on the free tier, with “hard spending caps” instead of open-ended usage billing. (ghost.build 1) (ghost.build 2) Ghost is not presenting this as a general cloud console for humans. Its learn page says there is “no dashboard,” “no UI,” and “CLI and MCP only,” which puts the product directly in the workflow of coding agents rather than traditional database administrators. (ghost.build) The product has been shipping quickly in April. Ghost’s changelog says it added cost reporting in `ghost status` on April 22, Homebrew install support on April 21, dedicated instances on April 20, and open-sourced the command-line interface on April 17. (ghost.build) A YouTube demo from Tech With Tim on April 29 showed the Claude Code setup and framed Ghost as a way to give Claude persistent memory and disposable databases. The broader bet is that agents need safe state, not just bigger context windows. (youtube.com) (ghost.build)
