Research, then act, in the same conversation

Most SEO MCP servers are read-only: they surface numbers and stop. Because 23 of Opinly's 61 tools write, the conversation that finds a keyword gap is also the one that closes it.

RESEARCH
Competitors
Who they are, what they rank for, and who links to them.
Keywords
Ideas with volume, difficulty and intent; rank tracking across markets.
Backlinks
Referring domains, page-level links, and gaps against any competitor.
Site audits
Technical issues, per-page findings, and crawls on demand.
AI-search visibility
How often ChatGPT, Gemini and Claude name your brand versus competitors, per prompt, over time.
ACT
Publish
Draft, edit, schedule, publish and unpublish posts, with optional sync to your connected CMS.
Organise
Folders, tags, authors, title images, and content clusters.
Monitor
Track keywords and competitors, and add the prompts you want measured in AI answers.

THEN ASK
  • “How does my site compare to competitors on keyword rankings, and where are the biggest gaps?”
  • “How visible is my brand in AI answers this month, and which competitor is winning?”
  • “Which sites link to my competitors but not to me?”
  • “Summarise my latest site audit and list the top technical issues to fix.”
  • “Draft a post on competitive analysis, tag it, and schedule it for next Monday.”

Frequently asked questions

Which SEO tools have an MCP server?
Most major SEO platforms now expose one, but nearly all of them are read-only — they return data and stop. Opinly is built to act on it: 23 of its 61 tools write, so the assistant can publish the post rather than just describe it.
How do I connect my SEO data to Claude?
Add https://mcp.opinly.ai/mcp as a custom connector in Claude, sign in with your Opinly account, and approve access. No API keys and nothing to install — it is a remote server over Streamable HTTP with OAuth 2.0.
Can I run SEO from ChatGPT?
Yes. Any MCP client that supports remote servers with OAuth 2.0 connects the same way, including ChatGPT, Cursor and VS Code.
What can it change in my workspace?
Every tool declares whether it reads, writes or destroys, so your client can ask before anything changes. The split is 32 read, 23 write and 6 destructive.
Do I need an Opinly account?
Yes — an account with an active subscription. LLM-visibility tools need the AI-search add-on. All data is scoped to companies you own or belong to, and every call is authorised against your organisation role.
