Compatible with every major AI agent and IDE
What is the JSON-LD SEO Compiler MCP Server?
When a Martech AI Agent publishes an article or product to a CMS like WordPress, it often generates structured data (Rich Snippets). However, LLMs frequently hallucinate property names or forget mandatory attributes like @context and @type. Google rejects these invalid schemas. This MCP solves that perfectly.
The Superpowers
- Strict Construction: Takes a simple JSON payload and deterministically injects all required Schema.org boilerplate to ensure Google compliance.
- Zero Hallucination: Outputs a perfectly formatted `` block ready for direct HTML injection.
Built-in capabilities (1)
Pass the Schema.org type (Article, Product, FAQPage, etc.) and a JSON string of properties. The engine injects @context and @type automatically and returns a valid <script type="application/ld+json"> block. Compiles 100% compliant Google JSON-LD schema blocks for SEO. Prevents AI hallucination of invalid @context or @type attributes

Frequently asked questions
Why do I need an engine for this?
LLMs can easily break JSON syntax (missing quotes, trailing commas) which causes HTML parsers to crash. This engine parses and stringifies deterministically.
Does it support all Schema types?
Yes! You can pass any valid Schema.org type like Article, Product, FAQPage, or LocalBusiness.
Can it nest objects?
Yes, just pass a nested JSON payload and the engine will compile it correctly.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query JSON-LD SEO Compiler tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
