Data Delaware vs Myvariant
In-depth architectural comparison of the Data Delaware and Myvariant MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Data Delaware
Developer Tools · Remote HTTP/SSE
Quality: 49/100 (Fair) | Auth: No auth required
Myvariant
Developer Tools · Remote HTTP/SSE
Quality: 45/100 (Fair) | Auth: No auth required
Verdict Summary: Choose Data Delaware if you need specialized Developer Tools tools running via a hosted cloud SSE transport. Choose Myvariant 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?
D
Choose Data Delaware when:
You need dedicated capabilities in the Developer Tools domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Search the Delaware 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.
query
Run a Socrata SoQL query against a Delaware Open Data dataset by resource_id (e.g. "5zy2-grhr"). Filter with where/select/group/order (SoQL clauses, without the leading $) plus limit/offset. Returns matching rows as JSON.
metadata
Get a Delaware Open Data dataset's schema + metadata (columns, types, row count, category, last-updated) by resource_id, e.g. "5zy2-grhr".
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…
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Data Delaware is categorized under Developer Tools and uses a remote streaming HTTP/SSE transport. In contrast, Myvariant belongs to Developer Tools using remote streaming HTTP/SSE transport. Select Data Delaware when you need capabilities focused on developer tools and Myvariant when you require tools for developer tools.
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.
