Openunfurl

Wraps a zero-signup link unfurl API as a single MCP tool. Give it any public URL and get back title, description, image, favicon, Open Graph, Twitter Card, and oembed metadata as structured JSON. No API key, no account, just a stateless HTTP call. Built specifically so autonomous agents can preview links without a human to handle signup flows. The underlying REST endpoint parses static HTML only in v0.1, so JavaScript-rendered SPAs will return whatever's in the initial payload. Rate limited per instance to prevent abuse, with SSRF guards against private IPs. Useful when you need an LLM to summarize or decide whether to follow a link before actually fetching it.
