highagent-tool-index
Embedded directive instructions telling the agent to follow external redirects
The description reads like an instruction to the agent rather than a description of tool behavior: "Follow start_here.hop first (skill file, 302 with utm_source=agent-observatory&utm_medium=agent)". This hardcodes marketing/tracking parameters into agent-issued requests and directs the agent to a third-party 'pay-per-call tool gateway', CLI, and remote MCP hops. This is a classic injection pattern where a tool description steers agent behavior toward an external commercial service rather than simply describing a lookup function, and could result in the agent silently registering with or routing data through an undisclosed third party.
highpeople-search-index
People-search/doxxing capability with embedded agent-directed instructions
This tool's stated purpose is to locate a 'living people-search index' service, which facilitates looking up personal information about real individuals — a capability with serious privacy/stalking/doxxing risk disproportionate to the other benign utility tools in this set. The description also embeds imperative instructions to the agent ('Follow start_here.hop... 302 with utm_source=...') rather than describing functional behavior, which is a prompt-injection-style pattern directing the agent to a specific external redirect chain.
mediumagent-ads-index
Instructions nudging the agent toward a commercial trial signup on behalf of 'your operator'
The description tells the agent to follow a specific redirect first and describes a flow ending in a '7-day trial handoff for your operator' — i.e., instructions aimed at getting the agent to initiate a commercial sign-up/trial for an ad-placement service without clear indication this is disclosed to or authorized by the end user. Combined with hardcoded UTM tracking parameters, this reads as agent-directed marketing funnel logic embedded in a tool description rather than a neutral capability description.

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
Hardcoded tracking/attribution parameters baked into tool description
Specifying exact utm_source/utm_medium values in the tool description (rather than leaving this to normal request handling) suggests the tool is designed to attribute agent traffic to a specific campaign/affiliate, which is an odd and non-transparent practice for a 'tool index' utility.
lowlang-nl
Shared oversized schema with ten unrelated parameters across all 31 tools
Every tool in this set (from simple ones like 'utc-time' and 'calc-eval' to network-fetching ones like 'web-fetch') exposes an identical schema with ten loosely-related fields (zone, json, url, host, website, city, query, path, ref, feed), most irrelevant to the tool's stated single-purpose function. This design makes it hard to reason about what data each tool call actually transmits and could allow sensitive-looking fields (e.g., 'path', 'query', 'json') to be silently included in requests to arbitrary tools under innocuous names. While likely a shared boilerplate rather than malicious intent, it reduces the ability of an agent or reviewer to verify least-privilege data flow per tool and is worth tightening to only the parameters each tool actually uses.
