Yoast API
Yoast ships four documented APIs: a read-only REST endpoint returning a URL's full meta tags and schema.org JSON-LD, plus PHP-only Surfaces, Metadata, and Schema APIs inside WordPress. Everything is free and self-serve, but nothing can be written via REST and there are no SDKs.

Yoast scores A on Supergood's API Report Card. Yoast ships four documented APIs: a read-only REST endpoint returning a URL's full meta tags and schema.org JSON-LD, plus PHP-only Surfaces, Metadata, and Schema APIs inside WordPress. Everything is free and self-serve, but nothing can be written via REST and there are no SDKs.

Yoast is the leading WordPress SEO plugin and a broader on-page SEO software company that helps website owners optimize content for search engines and, increasingly, for generative-AI surfaces.
Vertical: WordPress SEO plugin / on-page SEO software (horizontal SaaS layered on top of WordPress + Shopify). A site owner installs the Yoast SEO plugin in WordPress, picks a focus keyphrase per post/page, and works the green/orange/red checklist for SEO and readability.
9/10 within WordPress, 5/10 across the broader web.
Partially.
Founded 2010 in Wijchen, Netherlands by Joost de Valk as the 'WordPress SEO by Yoast' plugin.
REST API is read-only, no POST/PUT support means you cannot programmatically update SEO titles, descriptions, focus keyphrases, or redirects via the API; all writes must go through the WordPress admin or direct DB writes. Returns 404 for URLs without indexable data, requiring an admin-side 'Optimize SEO Data' run or post update to populate, confusing for developers building headless sites.

Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. As of August 2026 there is no official Yoast MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. Yoast doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
