SEOLint is a Model Context Protocol server that turns Claude into a persistent SEO agent — scanning your site, storing every issue it finds, and telling Claude what to prioritize fixing next. Unlike traditional SEO tools that require you to learn a separate dashboard, navigate reports, and manually translate findings into action items, SEOLint works entirely within the Claude interface you're already in. The setup takes roughly two minutes: connect SEOLint as an MCP server in Claude, point it at your site, and start asking questions. The server maintains a persistent store of site issues so Claude has longitudinal context across sessions — it knows what was found last week, what's been fixed, and what's deteriorated. Built by Daniel Smidstrup, with a free tier available. The positioning as "no separate dashboard" is smart and increasingly common: as Claude becomes a workflow hub rather than a chat interface, MCP servers that bring domain expertise directly into that context — rather than fragmenting attention across tools — will win adoption by reducing context switching. SEOLint is a clean early example of that pattern in a domain (SEO) where tool fatigue is real.

Reviewer scorecard
“Two-minute setup and it lives in Claude — that's the right distribution strategy for developer-side SEO. The persistent issue store giving Claude longitudinal context is the feature that makes this actually useful rather than a one-shot scanner.”
“No API to speak of. It's a publishing platform, not a developer tool. Built-in audience is the value proposition.”
“SEO is a domain full of shallow tools that produce impressive-looking scans and low-impact recommendations. 'No dashboard' is only an advantage if the underlying analysis is good — and Claude's SEO reasoning is only as strong as what SEOLint feeds it. The site scanner quality matters more than the interface choice.”
“10% revenue share is expensive at scale, but the built-in discovery and reader network provide real value.”
“Domain-specific MCP servers that make Claude the single interface for professional workflows will erode every category of B2B SaaS that competes on UI alone. SEOLint is an early signal: the product is the MCP context, not the dashboard.”
“For content creators who want to stay in Claude for writing and also get SEO feedback without switching apps, this is genuinely convenient. Being able to ask 'what SEO issues should I fix before publishing this?' inside the same tool where I'm writing is a real workflow improvement.”
“The simplest way to start writing and getting paid. The network effect brings readers you wouldn't find elsewhere.”
