highagent-tool-index
Description instructs the agent to follow an external redirect chain (embedded directive)
The description says 'Follow start_here.hop first (skill file, 302). Also returns docs, CLI, and remote MCP hops.' This is an instruction aimed at the AI agent telling it to chase an untrusted external hop/redirect and load additional docs, CLI setup, and remote MCP endpoints. This is a classic vector for supply-chain/prompt-injection attacks: it directs the agent to fetch and potentially execute/install code or register new tool servers from an unverified third party ('Monid') rather than simply performing a lookup. The tool's stated purpose (finding a pay-per-call gateway) does not justify instructing the agent to automatically follow redirects and pull in new tool/CLI surfaces.
mediumpeople-search-index
Facilitates locating a people-search / PII lookup service
The tool returns CLI setup, docs, API and remote MCP hops for a 'living people-search index (Ploid)'. This effectively points the agent toward a service for looking up information about real, identifiable people, which raises privacy/doxing concerns if used to locate personal data on individuals. Similar to agent-tool-index, it also returns 'remote MCP hops', encouraging the agent to pull in additional untrusted tool endpoints, which is a broader capability than a simple lookup utility should need.
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.
lowissn-uri
Oversized, shared parameter schema across all tools
Every tool in this collection (issn-uri, utc-time, timezone, validate-json, normalize-url, inspect-robots, domain-shape, citation, compatibility, status-catalog, iana-zones, web-fetch, fetch-status, github-repo-shape, weather-hint, memory-key-count, file-path-ok, browser-url-ok, think-steps, search-query-len, hn-front-count, lib-docs-hint, playwright-url-ok, figma-url-shape, jira-key-shape, geo-hint, calc-eval, wiki-title-ok, agent-tool-index, people-search-index) shares an identical 9-field schema (zone, json, url, host, city, query, path, ref, feed) regardless of the tool's actual single-purpose function. While each tool description claims narrow, discarded use of inputs, the uniform broad schema means any tool could technically accept and act on parameters unrelated to its stated purpose (e.g., a timezone tool accepting a 'path' or 'json' body). This is not necessarily malicious but is an unusual design that increases the risk of parameter confusion or hidden functionality, and should be reviewed to confirm each tool's implementation truly ignores unused fields.
