A side-by-side look at the Onekgpd MCP and Gnomad Genetics MCP Server MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Onekgpd MCP for biology & bioinformatics work over a hosted endpoint; choose Gnomad Genetics MCP Server for biology & bioinformatics as a local process. You can also run both side by side in one mcpServers block.
GNOMAD_DATAFRAME_DROP_ENABLED, GNOMAD_MAX_VARIANT_BATCH.gnomad_get_variant, gnomad_get_gene_constraint, gnomad_list_gene_variants.Rows where the two servers differ are marked.

gnomad_get_variantFull population record for one or more variants — AC/AN/AF overall and per genetic-ancestry group, homozygote/hemizygote counts, quality flags, transcript consequence, in-silico predictors, and joined ClinVar significance.gnomad_get_gene_constraintGene loss-of-function constraint — pLI, LOEUF (`oe_lof_upper`) with confidence interval, observed/expected ratios, and Z-scores. By HGNC symbol or Ensembl gene ID.gnomad_list_gene_variantsEvery variant in a gene, transcript, or region with allele frequencies and predicted consequences, filterable by consequence class and max allele frequency.gnomad_get_coverageSequencing coverage across a gene, transcript, or region — mean/median depth and the fraction of samples over depth thresholds, per callset track.gnomad_search_clinvarGene-level ClinVar detail via NCBI E-utilities — classified variants, review status, conditions, submission counts, and gnomAD-compatible variant IDs, paged by offset.gnomad_dataframe_queryRun a read-only SQL `SELECT` across canvas tables staged by the list tools.gnomad_dataframe_describeList the tables staged on a canvas and their columns before writing SQL.gnomad_dataframe_dropDrop a named table from a canvas to reclaim memory. Opt-in via `GNOMAD_DATAFRAME_DROP_ENABLED=true` — off by default.Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
