Seedfast Claude Plugins

Official Claude Code plugins for Seedfast — realistic, relationally valid PostgreSQL test data generated from a live schema.

The Seedfast engine is closed source and runs as a hosted service. This marketplace is the open part: the plugin that wires the MCP server into Claude Code, plus the workflow knowledge that makes it useful. Installing a plugin is the entire setup — no config file to hand-edit, no environment variables to export.

Installation

/plugin marketplace add seedfast-ai/claude-plugins
/plugin install seedfast@seedfast

Claude Code prompts for anything the plugin needs during install. Then say what you want:

seed my local postgres with a few hundred orders across 50 customers

Non-interactively, for CI or a scripted team setup:

claude plugin marketplace add seedfast-ai/claude-plugins
claude plugin install seedfast@seedfast --config api_key=sfk_live_...

Team-wide setup (optional)

Add to a project's .claude/settings.json so teammates are prompted automatically:

{
  "extraKnownMarketplaces": {
    "seedfast": {
      "source": {
        "source": "github",
        "repo": "seedfast-ai/claude-plugins"
      }
    }
  }
}

Plugins

Plugin	Description
seedfast	Seeds a PostgreSQL database from a plain-English scope. Bundles the Seedfast MCP server and the plan-before-run workflow that keeps seeding safe

Requirements

Node.js 18 or newer. The MCP server ships inside the Seedfast CLI and runs from npx, so there is nothing to install separately.

Using Seedfast outside Claude Code

The MCP server works with any MCP client. Client-by-client configuration, the full tool reference, and a no-API-key smoke test live in seedfast-ai/seedfast-mcp.
