Start with a real question

Three ways to put it to work

01 / Compare UCITS ETFs

Find the fund behind the ticker

Compare funds tracking the same index by ongoing charge, domicile and payout. Treat exchange listings of one fund as one holding.

Find accumulating UCITS ETFs tracking MSCI World. Compare ongoing charges, domicile and exchange listings. Show each fund once and include data dates and coverage.

02 / Research global stocks

Go from a name to the evidence

Resolve the right listing, compare peers and inspect financial history, company risk and cached ML valuation and relative forecast signals.

Find Nestlé's primary stock listing, then compare its fundamentals, company risk and Bullrun's cached ML valuation and relative forecast signals with its peers. Explain what the signals measure, show dates and coverage, and link to the company research. Treat model signals as research context, not price targets.

03 / Review your portfolio

See what your holdings share

Connect your Bullrun account to inspect concentration, correlations and overlapping ETF holdings. Save paper portfolios for review.

Review my Bullrun portfolios. Show concentration and risk coverage, then check for duplicate underlying holdings in my ETFs. Do not create or change any positions.

Choose what you want to research

Add the endpoint to a client that supports remote MCP over Streamable HTTP.

Public research · no account or API key

https://mcp.bull-run.org/mcp

Use public stock, ETF, company risk, ML valuation and macro research without signing in.

My Bullrun account · Google authorization

https://mcp.bull-run.org/account/mcp

The account endpoint starts OAuth in your client for your own portfolios, saved research and reviewable drafts. Signing into this website alone does not authorize a client.

Connect Claude
  1. Open Customize → Connectors and add a custom connector named Bullrun.
  2. Paste your chosen endpoint. Complete Google authorization for the account endpoint.
  3. Enable Bullrun in your chat and try an example prompt.

Other MCP clients

Use the selected endpoint with a client that supports custom remote MCP over Streamable HTTP. Client availability and configuration formats vary.

Keep the useful part

Turn a good answer into research you can return to

Open contextual links to inspect charts, fund comparisons, ML signals and company networks. Connect your account and ask your assistant to save named tickers to your Bullrun research shortlist. Saving a shortlist does not trade or set up alerts.

Review paper-portfolio drafts in Bullrun before accepting them. Opening a link never accepts a draft or changes holdings.

Create a free account

Simple pricing

Free to start. Pro for more use.

Public research needs no API key or Bullrun account. A free account lets you save watchlists, screens and virtual portfolios. Pro costs CHF 5/month or CHF 50/year for higher usage.

Free daily limits and MCP fair-use limits apply. Pro has a higher MCP budget; it is not an unlimited data API. Your AI client's own subscription and usage costs are separate.

Stock prices use stored daily observations, not live quotes. Coverage varies by company and dataset; results include dates and limitations. Risk scores and model valuations are research context, not investment recommendations. Data & methodology · Privacy
