History and research — price history, company profiles, news, financial statements, analyst recommendations, holders, dividends and options.
Your portfolios — add buys, sells, income and recurring contributions under your brokers and accounts, see every holding valued live in your base currency with totals, P&L and day change, and undo any change.

Network and credentials

The plugin runs no local code. It connects to one hosted MCP server:

https://mcp.finance.brainrotcreations.com/mcp: MCP over streamable HTTP
OAuth 2.1 with dynamic client registration, served by the Brainrot account service; you sign in and approve the app at https://www.brainrotcreations.com

Credentials: a Brainrot account. Don't paste passwords or tokens into chat. Market tools work without signing in; portfolio tools act only on the signed-in user's own portfolios.

Data and privacy

Your portfolios are stored in your Brainrot account and only you, and apps you've approved, can read or change them; disconnect an app any time at connected apps. Market data comes from third-party sources and can be delayed; private-market prices are indicative. Brainrot Finance is for information only — it doesn't give investment advice or place trades.
