Glama couldn't complete the latest health check. If this server requires authentication, missing or expired test credentials may be the cause. A test profile lets Glama authenticate for health checks and discover tools; it is separate from your personal connections.

Scored across 43 tools
Many tools have overlapping purposes, particularly the ask_pipeworx family (ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded) and other data-retrieval tools like deep_research, validate_claim, and suggest_questions. Company-oriented tools (entity_profile, company_facts, compare_entities, recent_changes, resolve_entity) also overlap heavily, making it difficult to select the right tool. The few genomics tools are distinct but are surrounded by unrelated financial, betting, and utility tools with unclear boundaries.
Tool names are wildly inconsistent: some are descriptive phrases (ai_visibility_check, ask_pipeworx), some use underscores in compound nouns (generate_llms_txt, kalshi_weather_edge), some are single verbs (forget, recall, remember), and others are noun phrases (entity_profile, company_facts). There is no consistent verb_noun or other predictable pattern, making the naming chaotic and hard to navigate.
With 43 tools, the count is far too high for a server named 'Ensembl' that should focus on genomics. The vast majority of tools are unrelated to that domain (finance, prediction markets, subscriptions, memory, etc.), inflating the count without serving the apparent purpose. The scope is unclear and the tool count feels bloated and unfocused.
For a server explicitly named 'Ensembl', the genomic tool surface is severely incomplete: only seven tools (lookup, lookup_symbol, sequence, variation, vep, homology, xrefs) actually serve that domain, missing core features like regulatory regions, comparative genomics, or batch queries. The remaining 36 tools are irrelevant to Ensembl, so the server fails to provide adequate coverage of its stated purpose and would cause agent failures for common Ensembl tasks.
