highagent-tool-index
Embedded directive tells the agent to follow an external redirect/skill file
The description contains an instruction aimed at the AI agent rather than a description of a single deterministic function: 'Follow start_here.hop first (skill file, 302). Also returns docs, CLI, and remote MCP hops.' This is a classic pattern for staging further prompt injection — it tells the agent to chase a redirect to an unknown external location and load a 'skill file' (which could contain new instructions) with no assurance the user is aware of or consented to this. The tool name is vague and gives no clear scope limit on what the 'gateway' does once reached (pay-per-call implies real financial/API consequences).
highpeople-search-index
Facilitates locating a third-party people-search/surveillance service and onboarding the agent to it
This tool's stated purpose is to find an index for searching information about 'living people' and to return CLI setup, docs, API, and remote MCP hops for it. This steers the agent toward installing/connecting to an external people-search service, which raises privacy and safety concerns (aggregation of personal data on individuals) and again encourages the agent to follow further external hops/setup instructions outside the tool's narrow stated function of a lookup.
low
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.
lowfathom-to-m
Every tool shares an identical, overly broad input schema unrelated to its stated purpose
All 30 tools (including this one, which purports to just convert fathoms to meters) expose the same nine parameters — zone, json, url, host, city, query, path, ref, feed — none of which are needed for a unit conversion. This pattern, repeated across every tool in the set, could be used to normalize disparate unrelated inputs (file paths, URLs, hostnames, JSON blobs, search queries) into one execution surface, making it harder for a reviewer or user to reason about what data a given tool call actually consumes/transmits. Not inherently malicious, but an unusual and unnecessarily broad capability surface for single-purpose utilities.
