People who connect a market server to an AI app often expect more than they get, or fear more than is possible. Both come from not knowing where the edge of a read-only connector sits. The edge is simple, and it is worth knowing before you ask the first question.
What read-only means
A read-only tool returns data and changes nothing in the market or in your account. NoVo’s MCP server is built this way. Its tools look things up. None of them can place an order, and none can touch a brokerage account. The paid alert tools arm and cancel watches on your own key, which is a setting on NoVo’s side and not a trade. If the idea of a server is new, start with what an MCP server is.
What the agent can do
It can fetch a reading and tell you what it says. Ask about dealer positioning and it can call get_dealer_levels for SPY, QQQ or IWM. Ask how stretched volatility is and it can call get_volatility_record. Ask what is on the schedule and it can call get_economic_calendar. With a paid key it can read the undelayed map through get_equity_map and the weekend perps through get_stocks_onchain.
It can also do the work around the lookup. It can make several calls and set the results side by side. It can explain a term, compare two tickers, or turn a payload into three plain sentences. That is reading, and an agent is good at it.
What it cannot do
It cannot see your positions, because the server holds no account. It cannot buy, sell, stage or cancel an order. It cannot know anything the tools did not return, though a careless model may talk as if it does. And it cannot tell you what happens next. The data describes where things stand. A sentence about tomorrow did not come from the connector.
Why the limit helps
Think about the worst case. If an agent with a read-only connector gets something wrong, the result is a wrong sentence on your screen. You can check it and move on. If an agent with trading access gets something wrong, the result is a position. Those are different sizes of mistake.
The limit also makes the agent easier to live with. A client can run a lookup without stopping to ask permission each time, because nothing can be damaged by it. The reasoning is in why a read-only tool matters.
Where action comes from
If you want an agent that can act, the action belongs to a second server run by your broker, behind your broker’s own approvals. The agent reads from one and acts through the other. Keeping them apart is the arrangement described in pairing a market-data connector with your broker.
Where NoVo sits
The MCP & API is the read side only. Any MCP client can connect to it at https://novo-options.trade/api/mcp, and many of the tools answer with no key. What comes back is a reading with its time attached, and Dr. NoVo, the Financial Markets Super Intelligence, is one tool call away if you want it interpreted.
