Fulcra Context MCP

Covers the time starting at start_time (inclusive) until end_time (exclusive). Result timestamps will include tz. Always translate timestamps to the user's local tz when this is known. Args: metric_name: The name of the time-series metric to retrieve. Use `get_metrics_catalog` to find available metrics. start_time: The starting time period (inclusive). Must include tz (ISO8601). end_time: The ending time (exclusive). Must include tz (ISO8601). sample_rate: Optional. The number of seconds per sample. Default is 60. Can be smaller than 1. replace_nulls: Optional. When true, replace all NA with 0. Default is False. calculations: Optional. A list of additional calculations to perform for each time slice. Not supported on cumulative metrics. Options: "max", "min", "delta", "mean", "uniques", "allpoints", "rollingmean". Returns: A JSON string representing a list of data points for the metric. For time ranges where data is missing, the values will be NA unless replace_nulls is true.
