The plugin bundles the Sitearc MCP server with a set of skills. A skill turns a string of tool calls into a piece of work that ends somewhere useful.
The plugin is not public yet. Until it is, connect the MCP server directly. It gives your agent the same tools.

The skills
The plugin has 19 skills. Each one takes a site’s projectId. Ask your agent
to list your projects if you do not know it.
Setup and research
- seo-project-setup records a site’s goals, audience, competitors and key pages as shared context.
- keyword-research turns seed topics into a shortlist and saves the terms worth keeping.
- keyword-clustering groups keywords by intent and maps each group to a page.
- competitor-analysis works through one named competitor’s footprint and gaps.
- competitive-landscape maps the leaders in a market before you pick a rival.
- link-prospecting finds realistic link targets for a page worth linking to.
- local-seo audits a Business Profile and local rankings around a place.
- fanout-research studies the questions an assistant asks on a topic.
Reports and guidance
- seo-audit writes a one-page, plain-language report built around one action.
- seo-coach explains the workflows and suggests a next step.
- sitearc-site-brief reads what Sitearc knows about a site into context.
The review loop
- seo-loop runs the measured cycle, from brief to proposal to result.
- sitearc-apply-recommendation carries an accepted idea through to a pull request.
- sitearc-feedback-triage turns open review comments into work.
Writing
Sitearc runs no model, so your agent writes. These skills guide it.
- sitearc-write-content turns an approved brief into a draft.
- sitearc-review-content checks a draft before it goes to a person.
- sitearc-write-brand-copy suggests copy against the accepted brand.
- sitearc-brand-profile proposes changes to a site’s brand kit.
- sitearc-review-hero reviews the top section of a page.
The honesty rules
The seo-loop skill limits what your agent may claim. In short:
- Start each session with
get_project_brief. - Report no number a tool did not return.
- Do no arithmetic on measurements. Sitearc computes results.
- When a tool says inconclusive, stop there. No trend, no band.
- Approval belongs to a person. If a tool refuses, relay the refusal and stop.
- Every table names its source for each row.
