A side-by-side look at the BioMCP TS 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 BioMCP TS for biology & bioinformatics work as a local process; choose Gnomad Genetics MCP Server for biology & bioinformatics as a local process. You can also run both side by side in one mcpServers block.

gene_searchSearch genes by symbol, name, or keyword with chromosome filtergene_getGet detailed gene info by HGNC symbol with optional sections (core, pathways, protein, ontology, go, interactions, expression, protein_atlas, constraint, druggability, dosage_sensitivity, clinical_evidence, disease_associations, diseases, funding). Set `smart=true` to auto-resolve gene aliases (e.g…gene_diseasesGet diseases associated with a gene (DisGeNET / OpenTargets)gene_drugsFind drugs targeting a gene (OpenTargets)gene_trialsFind clinical trials for a genegene_articlesFind articles about a gene (federated across PubMed, EuropePMC, Semantic Scholar, arXiv, PubTator, LitSense; envelope `{ results, warnings?, errors? }` — per-backend failures ride in `errors`)gene_enrichPathway enrichment analysis for a gene list (Reactome)variant_searchSearch variants by rsid, HGVS, gene, ClinVar significance, frequency, CADDvariant_getGet detailed variant info with optional sections (frequency, predictions, clinical; `alphagenome_scores` currently returns an unavailability error pending reimplementation)variant_oncokbGet OncoKB cancer variant annotations (requires `ONCOKB_TOKEN`)variant_trialsFind clinical trials for a variantdrug_searchSearch drugs by name, mechanism, or keyword (envelope `{ results, hint? }` — when nothing matches, `hint` points mechanism/target queries at gene_drugs)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.
