VarynForge MCP server

Read your site. Forge your next ten articles. With briefs.

VarynForge is an SEO research SaaS that exposes its full workflow as MCP tools. Connect once from Claude Desktop, Cursor, Claude Code, Codex, or any MCP-compatible host — then ask your agent to set up a project, hand it your article ideas, and forge writer-ready briefs the host agent uses as its writing prompt.

• Free tier: forge briefs from your own ideas, 10/day
• Paid tier: run research to discover data-backed keyword opportunities and ranked competitor pages, then forge briefs from them. From $75/mo.
• 30+ tools across projects, research runs, keywords, clusters, competitors, content plans, briefs, and writer guidance
• OAuth-secured (Better Auth) — no API keys to manage

• get_account_status — Current plan, limits, locked tools, upgrade URL, plans summary.
• get_writer_system_prompt — Writer system prompt the host agent loads before drafting articles.

How walls work

Paywalled tools and rate limits never throw a generic error. They return a structured payload your agent reads directly:

{
  "error_code": "PAYMENT_REQUIRED",
  "reason": "Research runs require a paid plan",
  "remaining": 0,
  "reset_at": null,
  "upgrade_url": "https://app.varynforge.com/pricing?utm_source=mcp&utm_medium=tool_wall",
  "upgrade_rationale": "...",
  "what_unlocks": "Data-backed keyword opportunities, competitor pages, content plans",
  "alternative_free_actions": ["create_article_suggestion_with_input", "..."]
}

This lets your host agent surface the next step verbatim — including five alternative free actions when applicable.
