TDQS

A3.5/5.0

Scored across 46 tools

Disambiguation2/5

There is significant overlap among the core routing tools (ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, deep_research) and among the many Polymarket analysis tools (bet_research, polymarket_edges, polymarket_arbitrage, polymarket_edge_tracker, polymarket_fill_risk, polymarket_kalshi_spread). An agent would struggle to choose between these overlapping tools despite detailed descriptions. The WMATA tools are clearly distinct, but the Pipeworx meta-tools and prediction market tools create ambiguity.

Naming Consistency2/5

Naming is inconsistent. The WMATA tools follow a clean rail_/bus_ verb_noun pattern, but the rest mixes styles: ask_pipeworx variants, polymarket_arbitrage vs polymarket_edges vs polymarket_fill_risk vs polymarket_kalshi_spread (all different verb styles), plus single-word tools like forget, recall, subscribe, and multi-word ones like release_calendar_markets. No consistent verb_noun or prefix convention across the set.

Tool Count1/5

At 46 tools, the surface is far too large and heterogeneous. It bundles WMATA transit data, Pipeworx universal data routing, prediction-market arbitrage, memory, subscriptions, npm scanning, and llms.txt generation into one server. This exceeds any reasonable scope for a single MCP server and imposes a huge decision burden on agents.

Completeness2/5

The WMATA portion is complete for rail/bus (routes, stops, predictions, incidents, station info). However, the Pipeworx and prediction-market portions have severe gaps: the vast '6,402 tools' catalog is opaque (only meta-routers are exposed), memory tools lack a clear update mechanism, and there are no tools for managing the Kalshi side of the arb workflow. The set tries to cover too many domains and leaves each partially complete.
