Server Details

NREL MCP — wraps the US National Renewable Energy Laboratory developer API

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

A3.6/5.0

Scored across 31 tools

Disambiguation2/5

Multiple tools have overlapping boundaries: ask_pipeworx and ask_pipeworx_beta are exact duplicates in practice, and ask_pipeworx_grounded, deep_research, entity_profile, validate_claim, and bet_research all serve query-driven research with fuzzily separated purposes. The polymarket_* cluster also spreads opportunity discovery, arbitrage, fill-risk, and edge decay across tools that an agent could easily misselect between. Detailed cross-referencing helps, but not enough to remove the clutter.

Naming Consistency3/5

All names use snake_case and are readable, but the pattern is mixed: verb-first tools like ask_pipeworx and compare_entities coexist with noun-first tools like entity_profile and pipeworx_trending, plus bare-verb tools like forget and recall. The pipeworx_ and polymarket_ prefixes provide some grouping, but there is no uniform verb_noun convention across the set.

Tool Count2/5

31 tools is heavy for the apparent purpose, especially because the set mixes unrelated utilities (generate_llms_txt, scan_dependency, memory trio) with a large prediction-market suite and multiple overlapping query entry points. Many of these could be consolidated into a handful of core data-lookup tools with parameters, and the beta duplicate inflates the count.

Completeness4/5

The research/data domain is quite thoroughly covered: universal routing, grounded hallucination-resistant answers, claim verification, entity profiles, comparisons, deep multi-source research, and prediction-market analytics are all present. Minor gaps remain—no dedicated tool for fetching a pipeworx:// citation directly, and no way to update/correct the data itself—but these work around via resources and MCP resource/read functionality.
