SEO MCP vs Keywords Everywhere: Browser Extension vs API-First Keyword Research

Keywords Everywhere has been around for years. If you’ve done any SEO work, you’ve probably had it installed in Chrome at some point – that little widget showing search volume and CPC right in your Google results. It’s genuinely handy for quick checks.

More recently, they added an MCP server, which is great. But there’s a difference between a tool that added MCP as a feature and a tool that was built around MCP from day one. If you’re looking for a keywords everywhere alternative mcp that was designed for developer workflows, SEO MCP by Delulu9 is that tool.

Keywords Everywhere: The Browser-First Approach

Keywords Everywhere gives you search volume, CPC, competition data, intent classification, and backlink metrics. The browser extension is still the core experience – you see keyword data overlaid on Google, YouTube, Amazon, and other search engines as you browse.

The MCP integration extends that data to Claude and Cursor. It works. The free tier gives you basic access, and paid plans run $10 to $50 per month depending on usage.

The strength here is the visual, browsing-oriented workflow. If you do a lot of manual SERP research in a browser, Keywords Everywhere meets you where you already are.

SEO MCP: Built for the Terminal

SEO MCP takes a fundamentally different approach. There’s no browser extension. Everything runs through a REST API and MCP server. You install it, connect it to Claude Code or Cursor, and start querying keywords from your editor or terminal.

It pulls from Google, Bing, and Reddit. The intent categorization and difficulty scoring are built in. And it ships with ready-made Claude and Cursor templates that handle common keyword research tasks out of the box.

The pricing is $12/mo flat. No credits to track, no usage tiers to think about.

Comparison Table

Different Tools for Different Workflows

In the seo mcp vs keywords everywhere comparison, the deciding factor is how you work.

If you spend your day in a browser, researching keywords manually, checking SERPs, and building spreadsheets, Keywords Everywhere fits that workflow perfectly. The visual overlay is something SEO MCP can’t replicate.

If you spend your day in a code editor or terminal, writing content, building sites, or scripting SEO workflows, SEO MCP fits better. It was designed for that context. The Claude and Cursor templates mean you can run keyword research without leaving your editor.

The Reddit Factor

One thing Keywords Everywhere doesn’t have is Reddit-sourced keyword data. That’s increasingly important. Google’s algorithm now heavily favors Reddit content for commercial and comparison queries. Understanding which keywords drive traffic through Reddit threads gives you a content strategy advantage that pure SERP data misses.

SEO MCP pulls Reddit data alongside Google and Bing, giving you a more complete picture of where keyword opportunities actually live.

Recommendation

If you’re a marketer who lives in the browser, Keywords Everywhere is a proven tool with years of refinement. If you’re a developer or technical founder who wants keyword research integrated into your AI-powered coding workflow, SEO MCP is the better fit. At $12/mo with Reddit data included, it’s purpose-built for the way developers actually work.
