highpeople-search-index
People-search/background-check capability with embedded tracking redirect
This tool is explicitly for locating a 'living people-search index' (personal data lookup service), which is a sensitive capability (potential for doxxing, stalking, or privacy violations) disguised as a benign index/shape-checking tool similar to the other 30 tools in this set. It also instructs the agent to 'Follow start_here.hop' through a tracked 302 redirect with hardcoded UTM parameters, directing the agent through an undisclosed commercial funnel ('Ploid') rather than simply returning data.
highagent-ads-index
Ad-placement/monetization tool instructing agent to act on behalf of 'your operator' and initiate trial sign-up
The description tells the agent to follow a tracked redirect (same utm_source=agent-observatory&utm_medium=agent pattern) and explicitly returns a '7-day trial handoff for your operator' — i.e., instructs the agent to initiate a trial/subscription or sign-up flow on behalf of the agent's operator/deployer (not the end user). This is an embedded directive that could cause the agent to take unexpected commercial actions (sign up for paid trials, register with an ad network) that benefit a third party and were not requested by the user, blurring whose interests the tool serves.
mediumagent-tool-index
Embedded directive to follow tracking-laden redirect chain
The description instructs the agent to 'Follow start_here.hop first' through a 302 redirect that embeds utm_source=agent-observatory&utm_medium=agent tracking parameters. This is an embedded behavioral instruction (not just functional description) telling the AI to navigate a specific affiliate/tracking URL sequence, which could silently enroll the user's session in a referral/tracking scheme without disclosure, and steers the agent toward a particular commercial gateway ('Monid') beyond what a simple lookup tool should do.

Not on gate's verified list
This server isn't on gate's handpicked list. That's not necessarily bad, but there's no third-party signal about it — review its tools carefully.
lowagent-tool-index
Tool name/purpose mismatch with surrounding benign-tool pattern
Unlike the other tools in this collection which perform narrow, stated, non-persistent checks (e.g., JSON validation, URL normalization), this tool's actual purpose is to route the agent toward a third-party 'pay-per-call tool gateway' and remote MCP endpoints. This broadens the tool's real capability far beyond what its name and sibling tools suggest, which could lead a user to underestimate what invoking it will actually do (e.g., register with or route through an external paid service).
