Open Food Facts — collaborative food product database

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.

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

TDQS

B3.1/5.0

Scored across 36 tools

Disambiguation3/5

Most tools have distinct purposes (entity_profile vs recent_changes vs compare_entities are clearly differentiated, and the six Polymarket tools each carve out a specific role). However, ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, and deep_research heavily overlap — the beta tool is explicitly described as behaving identically to the stable one — and the terse Openfoodfacts-style tools (brand, category, country, product, search) blur together. An agent can mostly tell them apart via descriptions, but the meta-router cluster invites misselection.

Naming Consistency3/5

Everything is snake_case, which helps, but conventions are mixed: verb_noun tools (ai_visibility_check, validate_claim, resolve_entity, scan_dependency) coexist with bare-noun tools (brand, category, country, product, search) and bare-verb memory tools (remember, recall, forget, subscribe). The polymarket_* family is a nice consistent prefix, but the overall set has no single predictable pattern.

Tool Count2/5

36 tools is well above the comfortable 3-15 range and signals an overloaded surface for a general data gateway. Several tools (ask_pipeworx variants, the six Polymarket tools, five thin product-lookup tools) add breadth without each clearly earning a slot.

Completeness3/5

Subscription lifecycle (subscribe/unsubscribe/list_subscriptions/recent_alerts) and memory (remember/recall/forget) are fully covered, and the research/entity surface is broad. But the terse Openfoodfacts-style tools (brand, category, country, product, search) have no visible create/update/delete path, and there is no way to enumerate or manage saved Polymarket subscriptions beyond the generic feed, leaving notable gaps for a server claiming this scope.

  2. 1 tool update
    • Changedresolve_entity1 field changed
      • changedInput schema / properties / value / description
        Previous value: -"For company: ticker (AAPL), CIK (0000320193), or name. For drug: brand or generic name (e.g., \"ozempic\", \"metformin\")."New value: +"For company: ticker (AAPL), CIK (0000320193), or name. For drug: brand or generic name (e.g., \"ozempic\", \"metformin\"). Pass the ENTITY NAME ONLY — for a bond that is the ISSUER exactly as printed (\"NEW YORK ST DORM AUTH\"), never the question's full noun phrase (\"NEW YORK ST DORM AUTH revenue bonds\"): the FIGI lookup matches instrument names, so trailing security-class words match nothing."
