Overview

AI-generated overview

Validates structured data by extracting JSON-LD, microdata and RDFa from a URL or raw HTML in a single call.

What you can do
This remote MCP server checks structured data markup on web pages. According to its registry description, it extracts JSON-LD, microdata and RDFa from either a URL or raw HTML in one call, so an assistant can inspect what machine-readable data a page exposes. No individual tools are listed in the manifest.
When to use it
Useful when an assistant needs to verify or inspect structured data markup on a page, for example during SEO or metadata checks, or when auditing whether JSON-LD, microdata or RDFa is present and parseable.
Requirements
Runs as a remote streamable HTTP endpoint; no package, environment variable or header is declared. The manifest declares no authentication, so no credentials appear to be needed. Network access to the endpoint and to any URL being checked is required.
Before you install
The server fetches the URL or HTML you give it, so page content is sent to a third-party endpoint; avoid submitting private or internal pages. No authentication is declared, so anyone who knows the endpoint may be able to use it. No tools are listed, so verify behavior before relying on it.

Installation

In SourceWeft

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

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Dawaxwx%2Fstructured-data-check/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Score

83% 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.
