Überblick

Beschreibung vom Entwickler (englisches Original)

Free, no sign-up: global stocks, UCITS ETF costs and overlap, company risk and macro, all dated.

Die drei Säulen von PopNx MCP

Diese drei werden nie zu einer Punktzahl zusammengefasst: Meinungen, Messungen und Beliebtheit sind verschiedene Dinge.

Was du damit machen kannst

Für diesen Server haben wir noch keine Zusammenfassung in einfacher Sprache geschrieben. Unten stehen die Fakten, die wir aus der Registry gelesen haben.

  • Verbindung: Läuft in der Cloud

  • get_etf_index_group

    Answer "what is the cheapest way to track ?". 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-buy

  • get_etf_fund

    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, ask

Bullrun: Global Stock & UCITS ETF Research

An MCP server for researching stocks and ETFs beyond the US. Find global stock candidates, compare UCITS ETF costs and overlap, and inspect company risks from your MCP client. Every figure shows its date, reporting period and native currency, and missing data is reported as unknown. Public research needs no API key or Bullrun account. Connect your free Bullrun account when you want to save research, read your portfolios or create a reviewable paper-portfolio draft.

Free: 700 successful MCP tool calls per rolling 30 days. Pro and active trials: 1,000 successful tool calls per rolling 5 hours. Bullrun Pro costs CHF 5/month or CHF 50/year. See plans and subscription details, then connect the account endpoint through OAuth to use your Pro allowance. Website screening and manual research have separate allowances.

Connect

Add the hosted endpoint as a remote MCP server in your client. Public market research is anonymous. To save a research shortlist or work with your portfolios, add the account endpoint above and authorize the requested OAuth scopes. These features, including AI-generated drafts, are available to signed-in free accounts. Free use includes 700 successful MCP tool calls per rolling 30 days, per free account or anonymous network, shared across the official public, research and OAuth endpoints. Connected Pro and active-trial accounts get 1,000 successful tool calls per rolling 5 hours. Each successful call counts once, regardless of how much data it loads; failed calls use no allowance. Allowances refill automatically as earlier calls leave the rolling window. Temporary capacity limits and tool pacing may ask you to wait; follow the reply's retry guidance. Website and marketplace allowances are unchanged. Your shortlist persists in Research Shortlist, and paper drafts remain pending until you review and accept them. Saving never enables monitoring or email.

{

"mcpServers": { "bullrun": { "url": "https://mcp.bull-run.org/mcp" } } }

Configuration formats vary by client. See the connection guide.

Start with a research question

  • “Find Nestlé's stock listing and show the available company data.”
  • “List your preset stock screens, then find European companies with positive earnings and free cash flow.”
  • “Show six months of Apple's daily prices, RSI and moving averages.”
  • “Find peers for Microsoft and compare their fundamentals.”
  • “Show recent company news for NVIDIA, with publication dates and freshness.”
  • “Which UCITS funds track the S&P 500 at the lowest ongoing cost?”
  • “Compare the underlying overlap of these two ETFs.”
  • “Which companies share suppliers or customers with Apple?”

Use the prompt menu for find_ml_candidates (compare model candidates with business fundamentals), compare_ucits_costs (fund-level cost comparison) and research_shortlist_briefing (review your saved queue). These workflows retrieve research; saving requires your instruction.

Tools

Version 0.9.0 exposes 48 focused tools in both hosted and local builds (39 research tools on the research-only and marketplace connections). The exact tools and parameters are available through MCP tools/list.

The hosted server and local stdio build support MCP 2026-07-28 and older initialization-based clients. Existing server URLs and OAuth requirements stay the same; reconnect if your client caches the catalog. Server guidance is shorter, and get_financial_history defaults to five fiscal years of annual statements. Request years (1-15) and periodType: "quarterly" or "both" explicitly when you need more detail. Responses retain dates, currencies, coverage and growth summaries.

The consolidated tools preserve existing defaults and fetch extra analysis only when requested:

  • screen_stocks({action: "list_presets"}) lists transparent rules without running a screen. Pass a preset such as profitable_value to run it, or supply custom rules; do not combine preset and custom rule inputs.
  • compare_etfs({tickers: [...], include: ["overlap"]}) returns pairwise shared holdings, weighted overlap, snapshot dates and partial-coverage warnings. Other comparison modules can be requested alongside overlap.
  • get_portfolio_analytics({portfolioId, candidateTicker, includeLookThrough: true}) adds ETF/direct-holding duplicate exposure. It requires portfolio access and retains the selected privacyMode; ordinary analytics does not fetch holdings look-through.
Migrating older clients

The four retired names remain available in the opt-in compatibility catalog at https://mcp.bull-run.org/legacy/mcp. OAuth clients that need a login challenge can use https://mcp.bull-run.org/account/legacy/mcp. Both retain the existing authentication rules. The modern endpoints omit these aliases:

Legacy nameModern call
screen_stock_presetsscreen_stocks with action: "list_presets" or a named preset
analyze_etf_overlapcompare_etfs with include: ["overlap"]
analyze_portfolio_fitget_portfolio_analytics with candidateTicker and includeLookThrough: true
query_etfssearch_etfs, get_etf_snapshot, get_etf_holdings, and get_etf_timeseries, according to the requested operation

Reconnect after changing endpoints; modern and compatibility sessions cannot be shared. For local compatibility, run node dist/stdio.js --legacy-tools. Legacy responses retain their existing fields and units, including raw fractional ratios in query_etfs; modern ETF ratios use percentage points.

Read the returned coverage and dates. Stored prices are daily observations, not live stock quotes. Technical indicators and price returns use stored closes; an adjusted total-return series is not implied. Weekly/monthly bars are aggregated from daily data. News reads return cached articles and, except on the research endpoint, can request a bounded background refresh; an empty result is not proof that no news exists.

Consensus estimates use available Yahoo revenue/EPS targets and EPS revisions; EBITDA, management guidance and revenue revisions are not supplied by this feed. Estimate reads can queue a free consensus refresh, and US transcript reads a bounded import of the latest two calls from the existing free DefeatBeta source; the first cached response may be empty while that runs. The research endpoint (/research/mcp) queues nothing: its news, estimate and transcript reads return stored rows only, so every tool there is read-only. Non-US transcript coverage is not configured. Operating KPI observations remain limited to stored rows, with no broad KPI ingestion pipeline. Use get_company_data_coverage before relying on an optional dataset. Missing data is unknown. A risk band describes measured strain, and a model valuation gap describes relative pricing; neither is a price target or buy/sell recommendation.

The same UCITS fund can trade on several venues under different symbols. Resolve ISINs with get_etf_fund and treat those listings as one holding when evaluating overlap.

Shortlist access uses read:shortlist and write:shortlist. Reconnect the account endpoint to grant these scopes if you connected an older version. save_research_shortlist takes 1-20 exact stock or ETF listing tickers; confirmed saves and individual failures are returned separately.

Successful answers offer an optional contextual link to Bullrun's charts, screens, company networks or saved draft. Link descriptions identify settings that the app cannot reproduce. Opening a draft link never accepts it or changes holdings.

Local stdio build

The remote endpoint is the simplest connection. To build the connector for local clients or directory inspection:

npm ci

npm run build node dist/stdio.js

The stdio build reads public data from https://bull-run.org by default. Set BULLRUN_API_BASE to use another Bullrun API deployment. Anonymous stdio clients cannot read personal portfolios or create drafts.

Release verification

npm test

npm run test:catalog

The public repository contains the MCP connector, not the application database or data services. The connector source, version and catalog are synchronized from the application repository's release process. MIT license.
