MCP Tool Examples

This page contains example scripts intended for use as MCP tools. When developing MCP tool scripts, make sure they return a string value, as this is required for the MCP client's LLM to interpret the output correctly.

List of Models

Returns all models accessible for the user (in a CSV data) with following fields: Model name, Containing project name, Model ID, Case attributes, Event attributes, Case count, and Event count.

let result = Query(#{
	"Values": [
		#{
			"Name": "Model name",
			"Expression": "Name"
		},
		#{
			"Name": "Containing project name",
			"Expression": "Project.Name"
		},
		#{
			"Name": "Model ID",
			"Expression": "Id"
		},
		#{
			"Name": "Case attributes",
			"Expression": "ToJson(If(Status==\"Online\",OrderByValue(Flatten(EventLog.CaseAttributes.Name)), CasesDatatable?.ColumnNames ?? []))"
		},
		#{
			"Name": "Event attributes",
			"Expression": "ToJson(If(Status==\"Online\",OrderByValue(Flatten(EventLog.EventAttributes.Name)), EventsDatatable?.ColumnNames ?? []))"
		},
		#{
			"Name": "Case count",
			"Expression": "CasesDatatable?.NRows"
		},
		#{
			"Name": "Event count",
			"Expression": "EventsDatatable?.NRows"
		}
	],
	"Ordering": [
		#{
			"Name": "Containing project name",
			"Direction": "Ascending"
		},
		#{
			"Name": "Model name",
			"Direction": "Ascending"
		}
	],
	"Dimensions": null,
	"Root": "Models",
	"ContextType": "generic"
}).Collect();
return result.ToCsv();

Average case cost in specific model

Returns the average of the case Cost attribute value of all cases in the model with ID 1.

let result = Query(#{
	"Values": [
		#{
			"Name": "Average Cost",
			"Expression": "Column(\"Cost\")",
			"AggregationFunction": "average"
		}
	],
	"Dimensions": [],
	"Root": "Cases",
	"ModelId": 1,
	"ContextType": "model",
	"ProcessingMethod": "dataframe"
}).Collect();
return result.ToCsv();

Case details

Returns details of a specific case. The case ID is provided as an MCP parameter, so the following Input configuration is needed:

{
  "type": "object",
  "additionalProperties": false,
  "properties": {
    "CaseId": {
      "type": "string",
      "minLength": 1,
      "description": "Unique identifier of the case (i.e, Case ID). Cases may be orders, deliveries, invoices depending on the model name."
    }
  }
}

The above schema means that there is one input parameter named CaseId containing a textual value (which cannot be null or an empty string). In addition, no other parameters are accepted ("additionalProperties": false).

The tool script that returns details of a case ID including all case attribute values:

let modelId = 1;
let dataQuery = [
		#{
			"Name": "Start time",
			"Expression": "AggregateFrom(Events, \"Min\", TimeStamp, null)"
		},
		#{
			"Name": "End time",
			"Expression": "AggregateFrom(Events, \"Max\", TimeStamp, null)"
		},
		#{
			"Name": "Duration in hours",
			"Expression": "DurationBetweenDates(\"hour\", AggregateFrom(Events, \"Min\", TimeStamp, null), AggregateFrom(Events, \"Max\", TimeStamp, null), null)"
		},
		#{
			"Name": "Latest event",
			"Expression": "AggregateFrom(Events.WithRowNumberColumn(\"RowNumber\", [TimeStamp, EventType], [CaseId], [false, false]).Where(Column(\"RowNumber\") == 1), \"Any\", EventType, null)"
		},
		#{
			"Name": "Event count",
			"Expression": "Coalesce(AggregateFrom(Events, \"Count\", null, null), 0)"
		},
		#{
			"Name": "Event types count",
			"Expression": "Coalesce(AggregateFrom(Events, \"CountDistinct\", EventType, null), 0)"
		},
		#{
			"Name": "Repeating event types",
			"Expression": "Coalesce(AggregateFrom(Events, \"Count\", null, null), 0) - Coalesce(AggregateFrom(Events, \"CountDistinct\", EventType, null), 0)"
		},
		#{
			"Name": "Variation path",
			"Expression": "AggregateFrom(Events, #{\"Function\":\"Array\",\"Ordering\":[TimeStamp, EventType]}, EventType, null)"
		}
	];

let caseAttributes = ModelById(modelId).CasesDatatable.Columns.Name.{
	let caseAttributeName = _;
	dataQuery = Concat(dataQuery, #{
		"Name": caseAttributeName,
		"Expression": `Column(${ToJson(caseAttributeName)})`
	});
};

let result = Query(#{
	"Dimensions": null,
	"Values": dataQuery,
	"MaximumRowCount": 1,
	"Root": "Cases",
	"Filter": #{
		"Items": [
			#{
				"Type": "IncludeCases",
				"Items": [
					#{
						"Type": "CaseAttributeValue",
						"Attribute": "Case Name",
						"StringifiedValues": [
							"0" + orderID
						]
					}
				]
			}
		]
	},
	"ModelId": modelId,
	"ContextType": "model",
	"ProcessingMethod": "dataframe"
}).Collect();
return result.ToCsv();

Notes:

• The script uses the CaseId variable containing the provided CaseId parameter value (which is generated by the calling agent).
• The model ID is hardcoded, but the model ID can also be provided as an MCP parameter.
