At a Glance & Executive Verdict
Data Gr
Developer Tools · Remote HTTP/SSE
Quality: 33/100 (Emerging) | Auth: No auth required
Gdc
Developer Tools · Remote HTTP/SSE
Quality: 48/100 (Fair) | Auth: No auth required
Verdict Summary: Choose Data Gr if you need specialized Developer Tools tools running via a hosted cloud SSE transport. Choose Gdc if your workspace requires Developer Tools integration with remote web transport. Both servers can be configured concurrently in your client's
mcpServers manifest.Which MCP Server Should You Choose?

Gdc Tools (4)
list_projects
List NCI Genomic Data Commons cancer-genomics projects (TCGA, TARGET, CPTAC, etc.), ranked by case count. Returns project_id, name, program, primary site(s) and disease type(s). Keyless, open-access metadata.
get_project
Look up a single NCI GDC project by project_id (e.g. "TCGA-BRCA") and get its details plus summary counts (case_count, file_count). Keyless, open-access metadata.
search_cases
Search NCI GDC cancer cases (patients/samples) by primary site and/or project. Returns case_id, submitter_id, primary site, disease type and project_id. Keyless, open-access metadata.
search_files
Search NCI GDC genomic data files by project and/or data category (e.g. "Transcriptome Profiling", "Simple Nucleotide Variation", "DNA Methylation"). Returns file_id, file_name, data category/type/format, access level and file size. Keyless, open-access metadata.
