Server Details

Alpaca MCP — real-time US stock market data via the Alpaca Market Data API

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

A3.6/5.0

Scored across 34 tools

Disambiguation3/5

Several meta-routing tools overlap heavily: ask_pipeworx, ask_pipeworx_beta (explicitly identical right now), ask_pipeworx_grounded, and deep_research all answer questions, while discover_tools/suggest_questions both serve discovery. Entity tools (entity_profile, recent_changes, compare_entities, resolve_entity, validate_claim) and Polymarket tools (edges, arbitrage, edge_tracker, fill_risk, bet_research) are more clearly separated by their verbose descriptions, but the entry points still require careful reading to choose correctly.

Naming Consistency4/5

All tool names use snake_case consistently, with predictable domain prefixes such as alpaca_, polymarket_, and ask_pipeworx_. The main deviation is that verb-first, noun-first, and single-word names are mixed (remember, recall, forget, entity_profile, recent_changes), but there is no camelCase or chaotic style mixing.

Tool Count2/5

34 tools is well above the typical 3-15 well-scoped range and includes redundant or low-value entries such as ask_pipeworx_beta (currently identical to ask_pipeworx) plus multiple discovery/onboarding tools. The count is also wildly disproportionate to the server name Alpaca, which accounts for only 3 of the 34 tools.

Completeness1/5

If the server is meant to expose Alpaca, it contains only three market-data tools (bars, intraday VWAP, snapshot) and lacks the core Alpaca surface: account, orders, positions, assets, market calendar, crypto, options, and news. The remaining 31 tools are unrelated Pipeworx meta-tools, leaving the apparent Alpaca domain severely incomplete.
