screen_stocksread-only

Screen the global Bullrun stock universe with the same rule engine as the app screener. Filter by sector, industry, country/countries, primary vs secondary listings, active vs inactive listings, lookback mode, AND/OR rule groups, comparison operators, money units, growth metrics and latest-value metrics. Returns a compact table of matching stocks. Read-only. Successful results include an optional

search_etfsread-only

Look up ETFs by name, ticker or ISIN, with classification, listing, index, distribution-policy, AUM, expense-ratio and yield filters. Best for finding a known fund. For ranking questions ("cheapest", "largest", "best performing", "most liquid") prefer screen_etfs, which evaluates the whole universe: here minAum and minYieldTtmPct are applied only to a bounded profile-enriched candidate scan, so do

screen_etfsread-only

Screen the WHOLE ETF universe by numeric rules and fund attributes in one pass — expense ratio, AUM, yield, trailing returns, volatility, liquidity, top-10 concentration, fund age and holdings count — combined with issuer, index, domicile, UCITS status, distribution policy, currency hedging and constituent look-through (holdingSearch finds funds by what they hold). Prefer this over search_etfs

get_etf_index_groupread-only

Answer "what is the cheapest way to track <index>?". Returns every fund tracking one index ordered cheapest fee first, deduplicated to one row per FUND rather than per venue listing (a five-venue UCITS fund is one choice, not five) with its listingCount and venues. Defaults to UCITS-buyable domiciles. Omit indexKey to list the available index families. Fees are percentage points and the response s

get_etf_fundread-only

Resolve one FUND rather than one listing. Given an ISIN (or any venue ticker of the fund) it returns the fund's identity, costs, index, distribution policy, wrapper type and every venue it is listed on with exchange and trading currency. Use this when the user quotes an ISIN, asks "which ticker do I buy on my exchange?", or when several tickers may be the same underlying fund. Ratios are percentag

get_etf_filter_optionsread-only

List the exact values accepted by the categorical filters on search_etfs and screen_etfs — asset classes, categories, index keys, product/wrapper types, regions, domiciles, currencies, exchanges, and (on request) issuers and focus strings. Those filters match exactly, so a guessed string returns zero rows and looks like "no such ETF exists"; call this first whenever a filter value is not already

get_etf_snapshotread-only

Fetch a modular snapshot for one exact ETF listing. The include array controls which of identity, classification, market, fund_data (NAV/AUM), costs, income, and benchmark are fetched and returned. Unrequested modules are omitted; requested-but-unavailable modules are named explicitly. Ratios use percentage points. Read-only. Successful results include an optional platformLink for continuing this

get_etf_holdingsread-only

Return the latest stored ETF holdings snapshot with opaque cursor pagination. The response reports the provider's stated holdings count, stored row count, covered weight, and whether the stored rows appear complete. Treat isComplete=false or null as partial look-through data. Historical as-of selection will be added when the upstream API exposes it. Read-only. Successful results include an optiona

get_etf_timeseriesread-only

Fetch ETF price or price-return history at daily, weekly, or monthly intervals. NAV, true total-return, benchmark, and premium/discount series are returned only when their required source data or an explicit benchmark ticker exists; unavailable requested series are named explicitly and never approximated with price returns. Read-only. Successful results include an optional platformLink for continu

get_etf_exposuresread-only

Calculate sector, country, currency, and broad asset exposure from the latest stored ETF holdings and Bullrun instrument mappings. Factor and thematic look-through are reported unavailable until dedicated source data exists. Coverage states how much fund weight and how many holding symbols were resolved, so partial top-holdings data is never presented as full exposure. Read-only. Successful result

get_etf_riskread-only

Calculate drawdown, annualized volatility, downside volatility, historical VaR, Sharpe, Sortino and Calmar ratios from stored daily close prices. With benchmarkTicker, also calculates beta, correlation, tracking error, active return and information ratio on aligned dates. Results are price-return risk, not distribution-adjusted total-return risk. Read-only. Successful results include an optional p

compare_etfsread-only

Return a normalized side-by-side comparison of two to ten ETFs across selected classification, market, fund-data, cost, income, benchmark, price-performance, price-risk, and holdings modules. Leaders are mechanical extrema, not recommendations. Currency and partial-holdings caveats are explicit. Read-only. Successful results include an optional platformLink for continuing this research or reviewin

analyze_etf_overlapread-only

Compare two to ten ETFs using their latest stored holdings. Returns pairwise shared holdings, weighted overlap (sum of the smaller weight for each shared holding), each fund's weight in shared names, and the largest duplicate exposures. Coverage is explicit because provider holdings may be partial top-holdings samples. Read-only. Successful results include an optional platformLink for continuing t

analyze_portfolio_fitread-only

Analyze an ETF candidate against one signed-in user's portfolio. Combines Bullrun's price-history candidate fit (correlation, beta and pro-forma volatility) with latest-holdings look-through that identifies direct and ETF-contained duplicate underlying positions. Coverage is explicit and partial provider holdings make duplicate exposure a lower bound. Requires OAuth read:portfolios. Read-only. Suc

simulate_etf_costread-only

Simulate expense-ratio, assumed bid/ask spread, commissions, and recurring contributions over a holding period. Compares the same gross-return path with and without costs and reports direct charges plus ending-value drag. Taxes, FX, market impact and brokerage-specific fees are excluded unless represented by the inputs. Read-only. Successful results include an optional platformLink for continuing

query_etfsread-only

Compatibility tool for older clients: search the Bullrun ETF universe and optionally bundle profile, recent prices, and latest holdings for an exact ticker. New clients should use search_etfs, get_etf_snapshot, and get_etf_holdings for smaller responses, structured output, quantitative filters, and explicit coverage metadata. Read-only. Successful results include an optional platformLink for conti

get_stock_metricsread-only

Fetch a consolidated metrics snapshot for a single stock by ticker: identity (company, exchange, currency, sector, industry, country, ISIN), latest daily price (OHLCV), latest valuation (market cap, P/E, dividend yield, annual dividend per share), the most recent reported financials (revenue, gross/operating income, EBITDA, net income, diluted EPS, free & operating cash flow, total debt, cash, tot

get_financial_historyread-only

Fetch 1-15 years of historical financial statements for one exact Bullrun ticker. Returns annual and/or quarterly rows grouped into income statement, balance sheet, cash flow, per-share metrics, margins, source currency, and annual growth/CAGR consistency checks.

get_quality_moat_metricsread-only

Compute annual quality, moat, earnings-quality, and capital-allocation metrics for one exact Bullrun ticker from existing financial statements: ROIC, ROE/ROA, ROIC-vs-supplied-WACC, accruals, cash conversion, capex intensity, dividend payout/growth, diluted share-count changes, and a buyback proxy. Read-only. Successful results include an optional platformLink for continuing this research or revie

get_forward_estimatesread-only

Fetch forward consensus revenue/EPS/EBITDA estimates, management guidance ranges, and estimate-revision percentages for one exact Bullrun ticker. Also derives simple forward P/E and PEG-style context from the latest close when EPS estimates are available. Read-only.

get_operating_kpisread-only

get_revenue_breakdownread-only

Fetch segment, geography, product, customer, or other revenue breakdown rows for one exact Bullrun ticker.

get_earnings_call_transcriptread-only

Fetch speaker-tagged earnings-call transcript chunks for one exact Bullrun ticker, optionally filtered by fiscal period or search text. Use this for management guidance language, analyst Q&A, and qualitative judgment that is not visible in financial statements. Read-only. Successful results include an optional platformLink for continuing this research or reviewing the exact saved draft in Bullrun.

list_portfoliosread-only

Start here when a portfolio question d

get_portfolio_contextread-only

Use when the user asks to look at, review, or analyze THEIR portfolio / holdings / positions — e.g. "analyze my portfolio", "how is my portfolio doing", "what's in my portfolio", "review my holdings", "how am I invested", "what should I improve". Fetches a deep snapshot of ONE of the signed-in user's portfolios: the summary (value, day change, total return), every holding (with position weight %

get_portfolio_analyticsread-only

Use when the user asks about THEIR portfolio's risk, diversification, or concentration, or whether to add a stock — e.g. "is my portfolio diversified", "how risky is my portfolio", "am I too concentrated", "what's my exposure to X", "should I add NVDA", "would AAPL improve my diversification". Fetches portfolio-level relationship analytics for one signed-in user's portfolio: correlation and annu

create_portfolio_draft

Use when the user wants you to BUILD or PROPOSE a brand-new portfolio for them — e.g. "build me a portfolio", "put together a dividend portfolio", "draft a portfolio of AI stocks", "create a new portfolio for $10k".

create_portfolio_from_positions

Persists a REVIEWABLE paper-portfolio draft built from the tickers you supply, sized by weight (percent) or by explicit USD amount. Unlike create_portfolio_draft this does NOT use the LLM and NEVER re-selects tickers: your ba

get_capabilitiesread-only

Discover what the connected Bullrun account can do BEFORE attempting an action, so you can plan instead of learning by hitting a 403. Reports whether you are authenticated and as WHICH identity (email + userId), whether the account has Bullrun Pro and why (subscription / trial / admin), the granted OAuth scopes, portfolio usage vs the free/max limits, and a per-tool entitlement map: create_portfol
