Invisible bot shield for HTML forms: the browser solves a proof of work and your server checks it.

What it does

Bot403 is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

From the publisher's description, Electra Index matched it to one capability: browser automation. That makes it a candidate for tasks such as fill web forms automatically or book appointments online.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

Live check

Electra Index connected to the hosted endpoint 2h ago

REACHABLE The endpoint answered but asks for an API key or a sign-in before connecting. Electra Index never sends credentials, so the tool list is not visible here.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
