AI schema markup generator: let your coding agent write the JSON-LD

Seogeoaeo.ai launched an MCP server at https://seogeoaeo.ai/api/mcp that lets coding agents such as Claude Code, Cursor and Codex generate JSON-LD schema markup through a dedicated tool call at 3 credits per run. The generator builds 16 schema types, including Article, Product, SoftwareApplication and FAQPage, from fields the agent passes in rather than free-form model output, and each run returns prioritized validator tips that agents can apply and rerun. The company positions the tool as a way to keep markup limited to content visible on the page, since chat models otherwise fill gaps with plausible but unsupported values such as ratings and prices.

The most practical AI schema markup generator for a developer is your own coding agent calling a dedicated tool: Claude Code, Cursor or Codex gathers the facts from your codebase, and the seogeoaeo.ai Schema Markup Generator turns them into JSON-LD for 3 credits a run. You get the agent's speed with output built from fields, not free-form text. Why not just ask the model Any coding assistant will write a JSON-LD block if you ask. The trouble is that a chat model fills gaps with plausible values. A rating, a price or a publish date that the page does not show breaks Google's rule that markup must describe content visible to readers, and a misplaced property can cost you eligibility for the rich result you wanted. A tool call narrows the job. The agent's part is reading your templates and content and deciding what each field should hold. The generator's part is producing the structure for a known type from exactly those fields, then previewing it against validator rules. Nothing is fetched, so the output only contains what the agent passed in. Connect the tools seogeoaeo.ai runs an MCP server at https://seogeoaeo.ai/api/mcp https://seogeoaeo.ai/api/mcp . Create an API key in your workspace, then add the server. For Claude Code: claude mcp add --transport http --scope user seogeoaeo https://seogeoaeo.ai/api/mcp --header "Authorization: Bearer YOUR API KEY" Cursor, Windsurf and other clients that read an mcpServers file take the same URL and header. VS Code uses .vscode/mcp.json , and the site's reference has a Codex config too. If you prefer plain HTTP, the same tool runs over the REST API. Agent runs cost the same as runs in the browser, and the agent can set a price cap per run, which keeps an overeager loop from spending more than you meant. A prompt that works Give the agent a narrow task with the type already decided: Read the pricing page template. Call the seogeoaeo schema-markup-generator tool with type SoftwareApplication, using only the name, URL, category, operating system, price and currency the page actually shows. Put the JSON-LD in a script tag with type application/ld+json in the page head. Telling it "only what the page shows" matters. Point it at the rendered template or the data source behind it, not at a marketing brief, so the values match what a visitor reads. The generator accepts fields such as ratingValue and ratingCount, and an agent will happily fill them if you leave the door open. Supported types The generator builds sixteen types: | Use | Types | |---|---| | Posts and docs | Article, BlogPosting, NewsArticle, HowTo, VideoObject | | Products and apps | Product, SoftwareApplication | | Site structure | WebSite, WebPage, BreadcrumbList | | People, places, dates | Organization, Person, LocalBusiness, Event | | Other | Recipe, FAQPage | It does not choose the type. If you are unsure, have the agent run the Schema Markup Checker on the live page first; it reports the types a page is missing along with parse errors and absent properties. Close the loop Once the change is deployed, ask the agent to run the checker against the URL and fix what it reports. Each seogeoaeo.ai run returns prioritized tips, and the reference tells agents to apply them and rerun until the result is clean. Finish with Google's Rich Results Test or URL Inspection if you want Google's own view. Keep an eye on the spend A generator run is cheap, but agents repeat themselves. Ask for one call per template rather than one per page, and review the diff before the agent moves on to the next template. Since every run shows its credit price first and failed runs are refunded, the cost stays predictable as long as the loop stays small. When to skip the tool call If your framework already emits structured data from a content model, change the model, not the page. And if you are writing one block for a static page you know well, asking the model directly and pasting the result into a validator is fine. For everything else, the seogeoaeo.ai schema generator https://seogeoaeo.ai/tools/schema-markup-generator is the cleaner way to let AI write your markup, because the agent supplies the facts and the tool supplies the structure.
