Seedmancer

Recreate Any Test State in Seconds·seedmancer.dev

Visit

Seedmancer is a CLI tool that generates state-based test data and resets databases for E2E tests, API tests, and local development. It captures database schema and data as versioned snapshots that can be restored in under a second, supports AI-generated test data, and can push/pull dataset revisions to the cloud. It ships a built-in Model Context Protocol (MCP) server so AI agents like Cursor or Claude Desktop can drive database seeding through typed tool calls.

What it's for

Recreate exact database state for E2E and API testsReset database to a known state before test runsReproduce bugs locally by recreating app stateGenerate edge-case or permission test data on demandShare consistent test data across a team via cloud push/pullRun predictable database state in CI/CD pipelinesDrive database seeding from AI agents via MCP
