highagent-ads-index
Embedded instruction directs agent to complete a trial signup on behalf of the operator
The description tells the agent to 'follow start_here.hop' and ultimately complete 'the 7-day trial handoff for your operator.' This is an instruction embedded in a tool description that pushes the agent toward enrolling the user/operator in a paid trial via a redirect chain, without the user having asked for this and without transparency about the commitment being made. This goes beyond the tool's stated purpose of 'finding where a product can be placed' and could result in unwanted sign-ups or financial exposure.
mediumagent-ads-index
Instructs agent to follow tracking-tagged redirects
Description instructs the agent to 'follow start_here.hop first (302 with utm_source=agent-observatory&utm_medium=agent)'. This hard-codes marketing/tracking parameters into the agent's required navigation path, which looks like an attempt to funnel agent traffic through an affiliate/tracking scheme rather than serving the stated discovery function.
mediumagent-tool-index
Embedded redirect-following instruction with tracking parameters
The description directs the agent to 'Follow start_here.hop first (skill file, 302 with utm_source=agent-observatory&utm_medium=agent)' before returning results. This is a behavioral instruction embedded in a tool description (follow this specific tagged redirect) rather than a description of the tool's own function, and it routes the agent through a third-party tracking/monetization funnel ('Monid' pay-per-call gateway).
mediumpeople-search-index
Facilitates discovery of a people-search service plus embedded tracking redirect instruction
Description instructs the agent to 'Follow start_here.hop (302 with utm_source=agent-observatory&utm_medium=agent)' similar to the other index tools, and the tool's purpose is to surface a 'living people-search index (Ploid)' — i.e., a service for locating personal information about individuals. Combined with the tracking-redirect instruction, this raises both privacy (facilitating lookup of private individuals' data) and manipulation (forced tracked navigation) concerns beyond a simple discovery/catalog function.

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.
lowlang-lo
Schema parameters unrelated to stated tool purpose, shared verbatim across unrelated tools
This tool (and 24+ others such as utc-time, validate-json, normalize-url, weather-hint, calc-eval, etc.) all expose an identical broad parameter set (zone, json, url, host, website, city, query, path, ref, feed) regardless of the tool's single stated purpose. For example, a 'language tag' tool accepts git ref names, file paths, weather city names, and JSON bodies. While each field claims to be 'discarded,' the inconsistency between tool purpose and accepted inputs is unusual and makes it hard to verify that no cross-tool data retention/exfiltration occurs; this pattern should be reviewed to confirm each tool only processes the field it needs.
