About Drupal in SEOmatic
SEOmatic connects to your Drupal site over JSON:API using OAuth2. Agents write new nodes and improve existing ones, and hand you anything your site has no field for rather than failing the whole save.
Last Updated
October 2026
Requirements
A Drupal site with the JSON:API module enabled (it ships with core) and the Simple OAuth module installed. You create a Consumer under Configuration > Simple OAuth whose user has permission to write content, then paste its Client ID and Secret. Meta fields additionally need the Metatag module.
How to Fix Drupal SEO from Hermes Agent
Step 1: Connect Drupal to SEOmatic
SEOmatic connects to your Drupal site over JSON:API, then works on the nodes you already have.
Step 1: Enable the JSON:API module (it ships with core) and install Simple OAuth.
Step 2: In Drupal, go to Configuration, then Simple OAuth, and create a Consumer. Give it a user with permission to write content, then copy the Client ID and Secret.
Step 3: In SEOmatic, go to Connections and select Drupal. Paste your site URL and both credentials, then pick the content type to work in.
Step 4: Agents propose changes with the reasoning attached, you approve what you want, and approved work is written to your site as a diff you can read and undo.
Step 2: Connect SEOmatic to Hermes Agent
Run this in your terminal. Hermes registers the server, opens your browser to sign in to SEOmatic, and stores the token. Then run hermes mcp test seomatic.
hermes mcp add seomatic --url https://app.seomatic.ai/api/mcp --auth oauthOther ways to connect are on the Hermes Agent page.
Step 3: Ask Hermes Agent, Then Approve
Paste any of these. Hermes Agent answers from your data and stages the fix; you approve it before it reaches Drupal.
- “Which of my Drupal pages lost the most clicks this month, and why?”
- “Stage new titles for my Drupal pages with high impressions and low CTR.”
- “Find Drupal pages Google has not indexed and tell me what is blocking them.”
- “Audit my Drupal homepage and rank the fixes by impact.”
What Hermes Agent Can Change on Drupal
New nodes written from research, plus rewrites of the title and body content on ones already published.
Agents set the URL alias, so your pages keep readable addresses instead of falling back to /node/123.
The agent arrives switched off and starts in approval mode. It earns more rope only when you give it.
A before and after view with the reasoning attached, so you see what changed and why.
Any change rolls back to its previous value. Low-risk edits that cost you traffic revert on their own.
Meta is written through the Metatag module when your site runs it. When it does not, agents hand you that work rather than assuming it is there.
Everything goes through core JSON:API and Simple OAuth, so there is nothing bespoke to install or keep updated.
Articles, basic pages or a bundle your team defined. Agents work in whichever one you point them at.
Only field values change, so your templates, Twig and site configuration stay exactly as they are.
Drupal sites differ enormously in which contributed modules they run, so agents check what your content types and modules actually provide before they write, and tell you about the rest instead of guessing at your field set.

No. By default every change SEOmatic proposes waits for your approval before it touches your site, and your assistant is told never to approve on its own. Approved changes are stored with the page's previous state, so any edit to an existing page can be rolled back. If you later want low-risk fixes to go ahead on their own, you can turn that on in your autonomy settings; changes to your URLs or indexing, and new content, still wait for you.

Connecting is free with no card: 5 questions a month from your own data, plus 10 once you connect Search Console, and site audits of up to 30 pages. Staging and publishing fixes is part of paid plans, which start with a 14-day free trial.
