此 MCP 可以做什么

Searches, compares, ranks, and summarizes a trading-card valuation dataset with numeric statistics and provenance information.

dataset_columns
Dataset columns and shape
The columns, which of them are numeric, the row count and the provenance banner of the Trading Card Value Checker dataset. Call this first to learn the schema.
输入模式
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
dataset_compare
Compare rows side by side
The rows of the Trading Card Value Checker dataset whose column is any of the given values, in the order given — for "X vs Y" questions.
输入模式
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['column', 'values'], 'properties': {'column': {'type': 'string', 'minLength': 1}, 'values': {'type': 'array', 'items': {'type': 'string', 'minLength': 1}, 'maxItems': 10, 'minItems': 2}}, 'additionalProperties': False}
dataset_provenance
Where this data comes from, and how to cite it
The source, the date it was computed, the licence and the citation for the Trading Card Value Checker dataset. Read this to attribute a figure correctly.
输入模式
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
dataset_row
Look a row up by an exact key
The rows of the Trading Card Value Checker dataset where a column equals a value exactly (case-insensitive).
输入模式
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['column', 'value'], 'properties': {'value': {'type': 'string', 'minLength': 1}, 'column': {'type': 'string', 'minLength': 1}}, 'additionalProperties': False}
dataset_search
Search the dataset
Rows of the Trading Card Value Checker dataset whose cells contain the query (case-insensitive), up to 50.
输入模式
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['query'], 'properties': {'limit': {'type': 'integer', 'maximum': 50, 'minimum': 1}, 'query': {'type': 'string', 'minLength': 1, 'description': 'text to look for in any cell'}}, 'additionalProperties': False}
dataset_stats
Summary statistics for a numeric column
count, min, max, mean, median and sum of a numeric column of the Trading Card Value Checker dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted).
输入模式
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['column'], 'properties': {'column': {'type': 'string', 'minLength': 1}}, 'additionalProperties': False}
dataset_top
Rank rows by a numeric column
The highest (or lowest) rows of the Trading Card Value Checker dataset by a numeric column — "which is the most/least X".
输入模式
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['column'], 'properties': {'limit': {'type': 'integer', 'maximum': 50, 'minimum': 1}, 'column': {'type': 'string', 'minLength': 1}, 'ascending': {'type': 'boolean', 'description': 'true for the lowest first; default highest first'}}, 'additionalProperties': False}
