Scored across 9 tools
Each tool has a clearly distinct purpose: describe_data for catalog, query_data for analysis, fetch_page for pagination, get_symbols for symbol lookup, get_account_status for account info, getting_started for onboarding, list_tickets/report_issue for support, recent_queries for history. No overlap.
Most tools follow a verb_noun pattern (describe_data, fetch_page, get_account_status, get_symbols, list_tickets, report_issue), but 'getting_started' uses a gerund and 'recent_queries' is adjective_noun, breaking the pattern. 'query_data' could be interpreted as a noun phrase. Minor inconsistency.
With 9 tools covering data catalog, query, pagination, symbol lookup, account status, onboarding, support, and query history, the count is well-scoped for the server's purpose. Each tool earns its place without redundancy.
The tool surface covers the full lifecycle from discovery (describe_data), analysis (query_data, fetch_page), identification (get_symbols), account management (get_account_status), onboarding (getting_started), to support (list_tickets, report_issue, recent_queries). No obvious gaps for the intended use case.

Set true when the user wants a chart or stat card: the link is then rendered with the chart type the engine picks from the data shape — a single-row result becomes a \"stat\" card, a multi-period series a line chart, etc. Does not change the JSON rows you receive, only how the view_url renders.", + "type": "boolean" +}

Input schema / properties / question / descriptionPrevious value: -"Full natural-language financial question. Not SQL. For complex multi-step workflows (backtests, Monte Carlo, multi-factor scoring), decompose into multiple calls — see mrmarket://capabilities resource."New value: +"ONE natural-language financial question, max 100 words (hard limit — longer is rejected as QUESTION_TOO_LONG, free of charge). Not SQL. Be precise, not redundant: metric(s) + universe/filters + time range is enough; the server picks columns and thresholds. Put ticker lists in `symbols`, never in this text. If 100 words feels tight, you are bundling multiple questions — split them into separate calls (see mrmarket://capabilities for the split test)." - added

Input schema / properties / symbolsAdded value: +{ + "description": "Explicit ticker universe for this question (e.g., a screening batch). STRONGLY preferred over pasting long ticker lists into `question`: the list is applied mechanically as a symbol filter (exact, order-independent), keeps the question readable, and is cheaper. Phrase the question generically (\"Find every golden cross event…\") and put the tickers here.", + "items": { + "type": "string" + }, + "maxItems": 2000, + "type": "array" +}
