What they did

falbala uses Claude with dash0, Linear and read-only production database access. Separately, they built an MCP on their GraphQL API in about 100 lines of code and config.

How it went

They debug user issues in minutes. The product MCP got heavy usage from day one and users flooded them with feature and data requests.

Worth knowing

Give agents read-only database credentials.
