For agents and assistants
Add Go Voltic as an MCP server
The same free scan the site itself runs, published as a Model Context Protocol server. One tool, one public endpoint, nothing to sign in to.
POST https://go-voltic.com/mcpWhat this is
Go Voltic scores a public web page for structure and content, AI visibility, speed signals, accessibility basics and trust, and counts how many of twenty-one published AI-agent standards the page meets. The endpoint above speaks the Model Context Protocol over streamable HTTP, protocol version 2025-06-18, with JSON-RPC methods initialize, ping, tools/list and tools/call. The server card is published at /.well-known/mcp/server-card.json and an OpenAPI description at /openapi.json.
The one tool
scan_site takes a single input, url: a public http or https address. Private and local hosts are refused. It returns:
| Field | What it holds |
|---|---|
| score | 0 to 100, weighted across five categories. |
| categories | Each of the five scored on its own. A category with nothing measurable reads null rather than zero. |
| findings | The first three open findings, each with its evidence and a specific fix. |
| locked | The rest of the findings, as a severity and a category only. |
| agent | How many of the twenty-one published AI-agent standards the page meets. |
| notMeasured | Checks that could not be run, and why. These are not presented as failures. |
A call takes roughly ten to thirty seconds, because it fetches the page, robots.txt, the sitemap and a few inner pages, then checks the published agent standards.
No account, and a limit stated plainly
There is no key, no token and no sign-in. A caller is limited by address rather than by credential: ten scans every five minutes, counted together across the free scan on the website, this endpoint and the agent-to-agent endpoint at /a2a. The eleventh call in a window answers with a wait time rather than a result.
What it reads, and what it keeps
A call reads the public pages of the site you point it at, the way an ordinary browser would: it identifies itself, obeys robots.txt, and does not submit a form or sign in. What is kept afterward is the same technical record the free scan on the website keeps: the address scanned, when it ran, its score and which checks did not pass. Nothing about who made the call is kept. See Legal for the full notice.
Adding it to an assistant
If your assistant supports adding a tool by a plain web address, often called a custom connector, add https://go-voltic.com/mcp. No key, token or sign-in step follows.
