Bullrun MCP

A hosted remote MCP server that turns Claude (and other MCP clients) into a stock-research analyst over global market data and your own portfolios.


Endpoint	`https://mcp.bull-run.org/mcp` — Streamable HTTP, OAuth 2.1 + PKCE
Web app	https://bull-run.org
Official MCP Registry	`org.bull-run/bullrun`
Glama connector	https://glama.ai/mcp/connectors/org.bull-run/bullrun
Privacy policy	https://bull-run.org/privacy

Bullrun is primarily a hosted service — there is nothing to install and no API key to manage for normal use. You point your MCP client at the remote endpoint and sign in with Google. This repository holds the connector's public metadata (server.json), connection docs, and a local stdio build of the MCP layer for directory/security checks. The Bullrun application and data services remain maintained separately.

Connect

Claude (web, Desktop, mobile) — requires a paid Claude plan:

Settings → Connectors → Add custom connector
Name it Bullrun, paste https://mcp.bull-run.org/mcp, and add it.
Click Connect and complete the Google sign-in / authorize step.

Claude Code:

hljs language-bash

claude mcp add --transport http bullrun https://mcp.bull-run.org/mcp

Full setup for Cursor, VS Code, and the MCP Inspector is in docs/mcp-connect.md.

What you can do once connected

Public market-data tools work for any connected client. The portfolio tools resolve your own Bullrun account after Google sign-in; the two draft tools require a Bullrun Pro account.

Tool	What it does
`screen_stocks`	Screen the global universe by sector / industry / country / market cap; sort by P/E, dividend yield, revenue or revenue growth.
`get_stock_metrics`	Consolidated snapshot for one ticker — identity (ISIN/LEI/CIK), latest price, valuation, most recent financials, description.
`get_financial_history`	1–15 fiscal years of annual/quarterly statements, per-share metrics, margins, CAGRs and consistency checks.
`get_quality_moat_metrics`	ROIC, ROIC-vs-WACC spread, ROE/ROA, accruals, cash conversion, capex intensity, dividend payout/growth, buyback proxy.
`get_forward_estimates`	Consensus revenue / EPS / EBITDA, guidance, estimate revisions, and derived forward P/E & PEG context.
`get_operating_kpis`	Domain KPIs — ARR, net revenue retention, RPO, billings, customer counts, payment & cross-border volume.
`get_revenue_breakdown`	Segment, geography, product or customer revenue splits.
`get_earnings_call_transcript`	Speaker-tagged earnings-call transcript chunks, fiscal-period filters and text search.
`query_etfs`	Search ETFs by ticker / fund name, category, focus, domicile; profile, price history and holdings for an exact ticker.
`list_portfolios`	Your virtual portfolios with value, day change, cost basis and total return. (sign-in)
`get_portfolio_context`	Deep snapshot of one portfolio: every holding with weight, sector and return, plus Bullrun's insights. (sign-in)
`get_portfolio_analytics`	Correlation/covariance, contribution-to-risk, factor exposure, sector/currency/country concentration, stress scenarios, and candidate-fit analysis. (sign-in)
`create_portfolio_draft`	Draft a new paper portfolio from a plain-English brief. Draft-only — saved for review, never changes a live position. (Pro)
`create_position_draft`	Suggest additions to an existing portfolio. Draft-only — saved for review. (Pro)

Authentication & privacy

The server is an OAuth 2.0 protected resource (RFC 9728). On first connect your client runs an automatic discovery handshake and sends you through Google sign-in; after you authorize, per-user tools resolve your Bullrun account. The MCP layer is a thin proxy with no database of its own — read tools return market data and your own holdings, the per-user read tools accept a privacyMode (full by default, or weights_only to return only relative figures), and the draft tools never mutate live holdings. See the privacy policy.

Local stdio build

The hosted endpoint above is the recommended integration. For directories that require building and running a local MCP server, this repo can run the MCP layer over stdio:

hljs language-bash

npm ci
npm run build
BULLRUN_API_BASE=https://bull-run.org node dist/stdio.js

Public market-data tools work without credentials. Portfolio and draft tools still require a Bullrun OAuth token in hosted clients and return an authentication-required error in anonymous stdio checks.
