Server Details

DummyJSON MCP.

The last two health checks of this connector failed. 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.

If you are the author, claim ownership, then add or update a test profile under Admin → Test Profile.

TDQS

A3.5/5.0

Scored across 49 tools

Disambiguation2/5

Multiple tools have overlapping answer/research purposes (ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, deep_research, validate_claim) and prediction-market tools cluster heavily (polymarket_edges, polymarket_arbitrage, polymarket_fill_risk, polymarket_edge_tracker, bet_research, polymarket_kalshi_spread). The descriptions provide routing guidance, but the set still requires long contextual reading to avoid misselection.

Naming Consistency3/5

All names use snake_case, which keeps them readable, but there is no consistent pattern: noun-only names (products, posts, recipes) are mixed with verb_noun names (validate_claim, resolve_entity, compare_entities), prefixed families (ask_pipeworx_*, polymarket_*, pipeworx_*), and singular/plural pairs. The mixed conventions are not chaotic, but they are not predictable.

Tool Count2/5

49 tools is far above the typical 3-15 range and feels heavy for a single MCP server, especially one named Dummyjson. The surface combines a small set of fake-data read tools with a large, unrelated Pipeworx data/research/prediction-market suite, so many tools do not obviously belong together.

Completeness2/5

For the apparent Dummyjson fake-data domain, the surface is mostly read-only and lacks create/update/delete operations for users, products, posts, comments, todos, quotes, and recipes, and it omits carts entirely. The Pipeworx additions are broad but do not resolve the Dummyjson coverage gaps, leaving a significant mismatch between server identity and tool surface.
