Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

compare_names

Side-by-side comparison of 2-3 names: full yearly series for each so trends can be plotted or contrasted directly.

namesarray, required

Names to compare, e.g. ["Michael", "James", "David"]

    }
  }
}

get_name_data

Returns full yearly birth count timeseries (1880–2025) for a given name for both sexes, including trend classification (rising/stable/declining/endangered/extinct), peak year, and peak count.

Argument	Type	Description
name*	string	The baby name to look up (case-insensitive)

Input schema (JSON)

{
  "type": "object",
  "required": [
    "name"
  ],

      "description": "The baby name to look up (case-insensitive)"
    }
  }
}

get_name_debuts

Returns every name that appeared in SSA records for the first time in the given year — genuine linguistic novelties, celebrity imports, invented spellings, or names newly crossing the 5-birth reporting threshold.

Argument	Type	Description

      "description": "Birth year to find debut names for"
    }
  }
}

get_name_diaspora

Returns the geographic spread of a name over time: where it first broke out (a clearly higher rate there than nationally), when it peaked nationally, which states broke out and when, and which states never did. `neverAdopted` lists the states that never passed the breakout test; it does not mean the name had no bearers there. Names first recorded nationally in 1910 or earlier, before state records begin, list all 51 states because no origin can be observed.

      "description": "The baby name to look up"
    }
  }
}

get_name_enrichment

Returns a precomputed profile for a name: estimated living population and median age, its popularity wave shape, cultural catalysts (events/media tied to spikes), historical demographic profiles by era (top occupations, region, urban vs. rural), and regional anomalies (states where it over-indexes).
