At a Glance & Executive Verdict
Myvariant
Developer Tools · Local stdio
Quality: 40/100 (Fair) | Auth: No auth required
Data Norfolk
Developer Tools · Local stdio
Quality: 43/100 (Fair) | Auth: No auth required
Verdict Summary: Choose Myvariant if you need specialized Developer Tools tools running via a local process. Choose Data Norfolk if your workspace requires Developer Tools integration with local subprocess execution. Both servers can be configured concurrently in your client's
mcpServers manifest.Which MCP Server Should You Choose?
M
Choose Myvariant when:
- You need dedicated capabilities in the Developer Tools domain.
- You prefer local stdio subprocess transport architecture.
- Your security boundary fits: No auth required (Free / Open Source).
- Primary tools included: query, variant, metadata.
D
Choose Data Norfolk when:
- You need dedicated capabilities in the Developer Tools domain.
- You prefer local stdio subprocess transport architecture.

Tools & Capabilities Breakdown
Myvariant Tools (3)
query
Search aggregated human genetic-variant annotations on MyVariant.info. Accepts an rsID ("rs58991260"), an HGVS id ("chr1:g.218631822G>A"), or a fielded query ("dbnsfp.genename:CDK2", "clinvar.rcv.clinical_significance:pathogenic"). Each hit merges dbSNP, ClinVar clinical significance, CADD/dbNSFP d…
variant
Get the full merged annotation for a single human genetic variant by its HGVS id (e.g. "chr7:g.140453136A>T"). Returns annotations aggregated from dbSNP, ClinVar (pathogenicity / clinical significance), CADD and dbNSFP (deleteriousness/conservation scores), and gnomAD (population allele frequencies…
metadata
Returns MyVariant.info build metadata: total indexed variant count, available annotation sources (dbSNP, ClinVar, CADD, dbNSFP, gnomAD), and their current release/build versions.
Data Norfolk Tools (3)
datasets
Search the Norfolk Open Data catalog of open datasets by keyword. Returns each dataset's resource_id, name, description, category and update date — pass the resource_id to query/metadata.
