## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## Common questions

### What is the Zactonz MCP server?

Zactonz is an MCP server listed in the public MCP registry as io.github.zactonz/zactonz-mcp. Screenshots, page to Markdown, link previews, DNS, SSL, WHOIS, QR codes and more for AI agents. This page covers its npm package (@zactonz/mcp).

### Is the Zactonz MCP server safe to use?

Zactonz scores 79 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 17 October 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Zactonz MCP server expose?

Zactonz exposes 19 tools: capture_screenshot, render_html, read_webpage, convert_html_to_markdown, preview_link, and 14 more. Their descriptions and schemas cost roughly 2,996 tokens of context every time the server is loaded.

### Is the Zactonz MCP server still maintained?

Zactonz is still listed as active in the MCP registry. We last reached this channel on 17 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Zactonz MCP server under?

Zactonz declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
