Biomart MCP

Queries Biomart for data using specified attributes and filters. This function performs the main data retrieval from Biomart, allowing you to query biological data by specifying which attributes to return and which filters to apply. Includes automatic retry logic for resilience. Args: mart (str): The mart identifier (e.g., "ENSEMBL_MART_ENSEMBL") dataset (str): The dataset identifier (e.g., "hsapiens_gene_ensembl") attributes (list[str]): List of attributes to retrieve (e.g., ["ensembl_gene_id", "external_gene_name"]) filters (dict[str, str]): Dictionary of filters to apply (e.g., {"chromosome_name": "1"}) Returns: str: CSV-formatted results of the query. Example: get_data( "ENSEMBL_MART_ENSEMBL", "hsapiens_gene_ensembl", ["ensembl_gene_id", "external_gene_name", "chromosome_name"], {"chromosome_name": "X", "biotype": "protein_coding"} ) >>> "ensembl_gene_id,external_gene_name,chromosome_name ENSG00000000003,TSPAN6,X ENSG00000000005,TNMD,X ..."
