What problem does it solve? SEO decisions often rely on guessed metrics because agents lack access to measured data. This Skill connects to OpenSEO's MCP-over-HTTP endpoint to supply real keyword volume, difficulty, SERP results, backlinks, local rankings, Search Console, and GA4 evidence, and falls back to qualitative research with metrics marked unknown when OpenSEO is not configured. ## Core Features & Use Cases - Measured SEO Evidence: Retrieves keyword metrics, ranked keywords, SERP competitors, backlink profiles, local rank grids, and site audits through OpenSEO's v0.1.6 MCP tool map. - Readiness and Auth Handling: Distinguishes hosted OAuth, headless API-key, and self-hosted modes via mktg seo status, never writing keys into the repository. - Cost and Mutation Controls: Separates free reads from credit-consuming research and shared-state mutations, requiring estimates and explicit approval for rank tracker spend. - Use Case: Before writing a keyword plan, run the Skill to check readiness, read the project context to avoid duplicate spend, pull keyword difficulty and volume for target terms, and sync results into brand/keyword-plan.md. ## Quick Start Check my OpenSEO connection status and pull measured keyword difficulty and search volume for the terms in my keyword plan.
