Overview

AI-generated overview

Generates Schema.org JSON-LD structured data for 12 schema types and validates existing markup, for SEO and rich-result work.

What you can do
Generate JSON-LD markup for 12 Schema.org types, including Person, Organization, Product, FAQ, Article, Event and VideoObject, through a general tool or type-specific shortcuts for Person, Product, FAQ, Article and Organization. List the supported schema types together with their fields. Validate existing JSON-LD markup and report errors and warnings.
When to use it
Useful when adding structured data to web pages for Google rich results, or when checking existing JSON-LD for problems, from an assistant instead of a separate web tool.
Requirements
Runs locally over stdio, typically launched with npx from the schema-gen-mcp npm package, so Node.js and network access for the package download are needed. No accounts, API keys or environment variables are declared.
Before you install
The server only generates and validates markup; the output still needs to be reviewed and placed on the page yourself. Validation results reflect the tool's own checks, not a guarantee of Google eligibility.

Installation

In SourceWeft

  1. Open Schema Gen in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
