Scored across 35 tools
Many tools have distinct purposes, but the set contains several overlapping meta-query/research tools (ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, deep_research, discover_tools, suggest_questions) and multiple Polymarket analytics tools whose boundaries require careful reading. Descriptions help, but misselection is plausible.
Almost all names use snake_case with a predictable verb_noun or noun_phrase pattern (resolve_entity, recent_changes, polymarket_fill_risk), with only a few single-word exceptions (ephemeris, lookup, remember). There is no chaotic mixing of conventions.
35 tools is heavy for a focused MCP server, and this set mixes a handful of astronomy helpers with dozens of unrelated Pipeworx data, research, memory, subscription, and prediction-market tools. The set is over-scoped rather than well-scoped.
If the domain is NASA Horizons, only ephemeris/observers/vectors/lookup are relevant and the surface is severely incomplete for that API. If treated as a broad Pipeworx platform, coverage is more complete, but the lack of a coherent domain makes the overall surface feel unfocused.
