Common questions

Is Returnolio safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.1) reached the registry 30 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Returnolio MCP server

This is the MCP server behind https://mcp.returnolio.com/mcp. It lets Claude, ChatGPT and other MCP clients read Returnolio's stock research for a signed-in user: company scores, the monthly Top 10, the screener, the market overview, the events calendar, and the user's own watchlist and portfolio.

It is listed in the official MCP Registry as com.returnolio/returnolio.

Connect

In Claude: Settings › Connectors › Add custom connector, then paste https://mcp.returnolio.com/mcp. You sign in with your Returnolio account. A Returnolio plan decides which tools answer. Setup for other clients is at https://returnolio.com/docs/features/mcp

Tools

All tools are read-only. None of them can trade, move money or change your data.

Tool	What it returns
`get_stock_score`	The score for one stock, with its five pillars: Quality, Earnings-Power, Value Margin-of-Safety, Momentum and Smart Money
`compare_stocks`	Several stocks side by side
`screen_stocks`	Companies that pass your filters
`search_tickers`	Find a ticker by name
`get_top10`	The monthly Top 10
`get_moonshot`	The Moonshot Detected picks
`get_market_overview`	The headline indexes and a macro snapshot: rates, inflation, jobs
`get_calendar`	Earnings, events and IPOs
`my_watchlist`	Your own watchlist
`my_portfolio`	Your own portfolio, as numbers only
`get_app_link`	A link to the matching page in the Returnolio app

Every answer carries a link to the same view in the app. Returnolio is a financial publisher, not an investment adviser: nothing here is a recommendation to buy or sell.

How it is built

The server is thin on purpose. It holds no database credentials and makes no product decisions. Each tool call goes to the Returnolio web app's gateway, which checks the user's plan again, applies rate limits, caps result sizes and attaches the disclaimer.

Sign-in: OAuth. Access tokens are signed by the web app with an Ed25519 private key. This server holds only the public key, so it can check a token but cannot make one.
Calls to the gateway carry a signature over the path, the query string and the token, so a token copied by hand cannot be replayed against the gateway.
Limits: live sessions per user and per server, an idle timeout, and rate limits on opening sessions. All are set by environment variables (src/config.ts).
Fails closed: the server will not start without a valid public key and service secret. It logs the variable's name, never its value.
Logs: one JSON line per event. Tokens and email addresses are dropped or masked (src/log.ts).

Run it yourself

cp .env.example .env   # fill in MCP_JWT_PUBLIC_KEY and MCP_SERVICE_SECRET

npm ci npm test # typecheck, build and every test npm start

Without a Returnolio gateway behind it the server starts, but every tool call is refused. The code is here so you can read how it handles your sign-in and your data.
