Nothing serious here today

Today is the operative word: we check Zovo Decision Tree every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

make
make_decision_tree
Use this when the user wants a decision tree drawn or solved: options of a decision, chance events with probabilities, and payoffs, for example "which option has the higher expected value" or "draw a decision tree for launching this product". Takes the tree as an indented outline or a JSON node list, the objective (max or min), a unit, decimals, a page size and a title. Rolls the tree back with fractions: the expected value of each node, the chosen option at each decision (ties listed), branch costs applied by a stated rule, and the risk profile of the chosen strategy. Refuses a tree whose chance probabilities do not add up to 1, naming the node and the sum, and end nodes without a payoff. Returns a summary, an interactive drawing, and PDF, SVG and CSV downloads. Up to 300 nodes. Does not estimate probabilities or give advice. Download links of large trees expire after about 1 hour.
tree
check_tree
Use this when the user wants a decision tree checked without a drawing, for example "do my probabilities add up to 1" or "is anything missing in this tree". Takes the same outline or node list and objective as make_decision_tree. Returns, for each chance node, the sum of its branch probabilities as a fraction and whether it is 1; end nodes without a payoff; probabilities on decision options; payoffs on nodes that have branches; single-option decisions; duplicate branch names; and the depth and node counts against the limits. When nothing is wrong it also gives the root expected value. Refuses a tree it is unable to read (unknown parent, a loop, two roots, over the limits), naming the line or id. Does not draw the tree or make files. Do not use it to estimate probabilities.

Zovo Decision Tree — questions

Answers built from our own checks of this server.

What can Zovo Decision Tree do?
It exposes 2 tools, read directly from the server on our last check. Among them: check_tree, make_decision_tree. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Zovo Decision Tree working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 420 ms. The bar chart above shows every period we have measured.
How do I connect Zovo Decision Tree?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Zovo Decision Tree need an API key?
No. Zovo Decision Tree completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Zovo Decision Tree?
It answers our handshake in 420 ms on average, which is faster than 30% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
