Tools (5)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • choice

    Pick the best option for the state. options: a list of option names, or {option: description or null} (1..255 options, order kept). Returns {"choice", "probabilities": {option: p}, "confidence": 0..1, ...}. confidence = (k * p_max - 1) / (k - 1) for k options: 0 = uniform, 1 = certain.

  • decide

    Ask several typed questions about one state in a single call (the state is read once). state: text, or a JSON object/array (serialised for the model). questions: {id: question}. A question is {"type": "noul", "instructions": "<statement or yes/no question>", "criteria"?: {"true": "...", "false": "..."}} {"type": "choice", "instructions": "...", "criteria": {"<option>": "<description or null>", ...}} {"type": "score", "instructions": "...", "criteria": ["<lowest level>", ..., "<highest level>"]} Score levels can also be {"label": "...", "description": "..."}. Returns the systemone-comp…

  • model_info

    Model id, context and question budgets, and which backend this MCP server uses.

  • noul

    Probability that a yes/no statement about the state is true. question: e.g. "The customer asks for a refund." or "Is the invoice overdue?" true_means / false_means: optional descriptions of what counts as true / false. Returns {"p_true": 0..1, "answer": p_true >= 0.5, ...}. Gate with your own thresholds.

  • score

    Place the state on an ordered scale. levels: 2..10 levels, lowest first; each a label or {"label": ..., "description": ...}. Returns {"score": expected level index (0 = first level, may fall between levels), "level": label of the most likely level, "legend": {index: label}, "probabilities": {index: p}, "confidence", ...}.
