what3words MCP — 3-word grid geocoding
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.

Scored across 35 tools
Multiple families of overlapping tools exist: ask_pipeworx, ask_pipeworx_beta (explicitly identical right now), ask_pipeworx_grounded, and deep_research all route questions to data sources; validate_claim overlaps with the grounded pipeline; and five polymarket tools (arbitrage, edges, edge_tracker, fill_risk, kalshi_spread) have blurred boundaries. The descriptions try hard to differentiate, but an agent can easily misselect.
Tool names are uniformly snake_case with no camelCase/PascalCase mixing, and domain prefixes (ask_pipeworx_, polymarket_, pipeworx_) create predictable groups. Minor deviations exist—single-verb tools like forget, remember, and autosuggest, plus noun-first names like recent_changes versus verb-first names like validate_claim—but the convention is readable and largely consistent.
35 tools is heavy for a single server, and several are near-duplicates or modes that could be parameters (ask_pipeworx_beta, scan_competitor_ai_presence, polymarket_edge_tracker). The what3words core needs only four tools, so the overall surface feels overgrown rather than tightly scoped.
For the combined data-gateway and what3words scope, coverage is broad: lookup/routing, grounding, entity resolution, comparison, validation, memory, subscriptions, Polymarket analytics, AI visibility, dependency scanning, and llms.txt generation are all present. Minor gaps include no subscription update operation, limited memory management beyond get/put/delete, and no generic tool-schema fetch beyond discover_tools.
