Server Details

Openverse MCP — Creative-Commons-licensed image + audio search.

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.

TDQS

A3.7/5.0

Scored across 42 tools

Disambiguation2/5

Several tools are near-duplicates: ask_pipeworx and ask_pipeworx_beta are explicitly identical today, and ask_pipeworx_grounded, deep_research, and validate_claim all route natural-language queries to the same underlying catalog. The multiple polymarket_* tools overlap heavily in detecting pricing edges, forcing agents to read long descriptions to pick correctly. The six Openverse media tools are distinct, but they are buried among 36 unrelated tools, compounding the confusion.

Naming Consistency3/5

The set mixes verb-first names like search_images, get_audio, remember, and validate_claim with noun-first names like company_facts, entity_profile, bet_research, and resolution_audit, plus domain-prefixed names like pipeworx_trending and kalshi_weather_edge. While consistently snake_case, there is no predictable verb_noun pattern, and near-synonyms like polymarket_edges, polymarket_edge_tracker, and polymarket_arbitrage do not disambiguate by name alone.

Tool Count2/5

At 42 tools, the set is well beyond the heavy 16-25 band, and the server named Openverse contains only 6 media-search tools. The remaining 36 tools cover unrelated domains such as financial data, prediction markets, memory, npm security, and subscriptions, making the count inappropriate for the apparent purpose.

Completeness2/5

The Openverse media sub-surface is complete with search, get, and related for both images and audio, but tool descriptions reference unlisted tools like get_company_financials, polymarket_market, and kalshi_market, creating dead ends for agents. The overall surface is a patchwork of several domains with no cohesive lifecycle coverage, leaving significant gaps in whatever singular domain the server claims to serve.
