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.

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.

Leaders are mechanical extrema, not recommendations. Currency and partial-holdings caveats are explicit. Read-only.

Generates a REVIEWABLE paper-portfolio draft for the signed-in Bullrun user from a natural-language brief (e.g. "a diversified European dividend portfolio"). Requires OAuth with the write:drafts scope and a Bullrun Pro account. This is DRAFT-ONLY and never changes any live position: the draft is saved to the user's account and appears in the Bullrun Portfolio tab under "Pending AI drafts", where the user reviews it and explicitly accepts it to create a new portfolio (or discards it). To suggest additions to an EXISTING portfolio instead, use create_position_draft. Tickers are chosen only from Bullrun's priced stock/ETF universe; pass instrumentUniverse for stocks only, ETFs only, or a mix. If the brief is vague, first ask ONE quick round of up to three multiple-choice questions (investing style, region focus, and size), each with a default the user can accept with "just pick for me", then build; skip any dimension the user already specified and do not interrogate across multiple turns.

Persist… Use when YOU (or the user) have ALREADY decided the exact holdings and want them saved as-is — e.g. after researching and settling on a specific basket with target weights. 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 basket lands exactly as given. It is NOT Pro-gated (it mirrors manual position entry, which is free) and needs only OAuth with the write:drafts scope. DRAFT-ONLY: the draft is saved to the user's Bullrun account and appears in the Portfolio tab under "Pending AI drafts", where the user reviews it and explicitly accepts it (creating a NEW portfolio) or discards it — it never changes any live position. Tickers must exist in Bullrun's priced stock/ETF universe; any that cannot be priced are returned in `unresolved` and skipped (use search_etfs / get_etf_snapshot / screen_stocks / get_stock_metrics to confirm exact tickers first). For a vague brief where the model should pick, use create_portfolio_draft instead.

Generates REVIEWABLE suggested additions for one existing Bullrun portfolio. Requires OAuth with the write:drafts scope and a Bullrun Pro account. This is DRAFT-ONLY: the suggested position(s) are saved to the user's account and appear in the Bullrun Portfolio tab under Pending AI drafts, where the user reviews and accepts them into the target portfolio or discards them. It never changes live holdings by itself. To draft a whole new portfolio from scratch use create_portfolio_draft; to test whether a specific named ticker fits, use get_portfolio_analytics with candidateTicker. Pass instrumentUniverse for stocks only, ETFs only, or a mix. If it is unclear, first confirm which portfolio (use list_portfolios when the user has more than one) and how many ideas (a single best idea or a few) in ONE quick step; otherwise just build.

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_portfolio_from_positions (free), create_portfolio_draft and create_position_draft (Pro-only), and whether another portfolio can be created now. Call this first when a draft/write tool might be gated, or to confirm which account a request will act on. Read-only.

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.

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 known to be valid. Read-only.

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 percentage points. Read-only.

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.

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 states how many funds publish no fee at all, so a "cheapest" claim is never made over silently omitted funds. Read-only.

Fetches portfolio-level relationship analytics for one signed-in user's portfolio: correlation and annualized covariance matrices across holdings, contribution-to-risk, concentration by weight and risk, currency/sector/country exposures, value/growth/momentum/quality/size proxy factor scores, scenario/stress tests (rates +100bp, oil -20%, USD +10%), and optional candidateTicker fit analysis showing correlation to the current portfolio plus pro-forma volatility (set candidateTicker when the user asks whether to add a specific stock). Pass a portfolioId from list_portfolios. The risk math only covers holdings with enough price history, dropping unpriced/unmatched ones (ETFs, funds, untracked tickers) and renormalizing all percentages over what remains; the response leads with a `coverage` banner (first text block) stating how many holdings were excluded, so never read these figures as the whole portfolio. For a plain holdings/value snapshot and the full matched/unmatched breakdown use get_portfolio_context instead. Requires OAuth (read:portfolios) and returns the caller's own data only. privacyMode defaults to "full"; "weights_only" hides absolute USD amounts while keeping weights, percentages, correlations and scores.

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 %, sector and return) and Bullrun's computed insights (benchmark comparison, concentration, diversification, dividend income). Pass a portfolioId from list_portfolios (call that first if the user hasn't named a portfolio). The response ALWAYS returns the complete holdings list with each position flagged matched/unmatched, plus a `coverage` summary: holdings that Bullrun can't link to its universe (ETFs, funds, untracked tickers) carry no weight, sector, insight or ML score, so weights/insights/ML below describe ONLY the matched subset. Read the coverage banner (the first text block) and never present matched-only figures as the whole portfolio. For risk/diversification math, correlations, factor exposure, or whether to add a specific stock, use get_portfolio_analytics instead. Requires OAuth (read:portfolios) and returns the caller's own data only. privacyMode defaults to "full" (absolute $ included); "weights_only" returns only relative figures. Read-only.

Use the exact ticker as listed on Bullrun - the native local-exchange symbol (e.g. AAPL, BMW, ABBN, NESN, or a numeric code like 005930), NOT Yahoo-style country suffixes like BMW.DE or ABBN.SW. If a ticker returns no data, use screen_stocks (by sector/country) to find the exact symbol. Read-only.

Lists the signed-in Bullrun user's virtual portfolios with computed summaries: name, base currency, total value (USD), day change, cost basis and total return, plus position counts. Start here when a portfolio question doesn't name a specific portfolio, then pass a portfolioId to get_portfolio_context or get_portfolio_analytics. Requires connecting this server to a Bullrun account (OAuth, read:portfolios scope) — it returns that user's own data only. privacyMode defaults to "full" (includes absolute $ amounts); pass "weights_only" to hide absolute money and return only relative figures (returns %, counts).

Prefer this over search_etfs for any "cheapest / largest / best performing / most liquid" question: search_etfs only filters a bounded candidate scan, while this evaluates the full universe and reports evaluatedCount and matchCount. Percentages are percentage points. This is the heaviest read in the API and is metered against a small per-day action budget, so build one well-specified screen rather than probing repeatedly.
