Fills a PostgreSQL database with relationally valid synthetic test data generated from its live schema, so an agent can seed a development or CI environment without production data. Plan a seed, run it and follow it to completion from the client. Runs as npx -y seedfast mcp and is published in the official MCP registry as st.seedfa/seedfast.

One MCP entry for every SQL Server you administer. Connections live in a single config file grouped by client or environment, hot-reloaded without restarting the agent, and every response says which server answered. Beyond running queries it returns execution plans, index layouts and stored-procedure source. Built for DBAs and consultants managing dozens of instances rather than a single database. Install with: npx -y @cevelas/mcp-sqlserver
