A side-by-side look at the Ensembl MCP Server and Genomics MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Ensembl MCP Server for biology & bioinformatics work as a local process; choose Genomics MCP for biology & bioinformatics as a local process. You can also run both side by side in one mcpServers block.
ensembl_list_species, ensembl_lookup_gene, ensembl_get_sequence.list_sources, search_datasets, describe_dataset.Rows where the two servers differ are marked.

ensembl_list_speciesList species supported by Ensembl with display name, common name, assembly, taxon ID, and divisionensembl_lookup_geneResolve a gene by symbol (synonyms and former symbols included) + species or by stable ID to its Ensembl ID, genomic location, biotype, and transcript listensembl_get_sequenceFetch the DNA, cDNA, CDS, or protein sequence for a gene, transcript, protein, or genomic regionensembl_query_regionFind genomic features (genes, transcripts, variants, regulatory elements, exons) overlapping a chromosomal regionensembl_predict_variantPredict functional consequences of a sequence variant using the Ensembl Variant Effect Predictor (VEP)ensembl_get_homologyFind orthologs and/or paralogs of a gene across species with percent identity and taxonomy levelensembl_get_xrefsRetrieve cross-database references for a gene — HGNC, UniProt, EntrezGene, OMIM, RefSeq, Reactome, and otherslist_sourcesList data and reference sources, their state and supported operations.search_datasetsSearch one archive/catalog for studies or datasets by text query.
Available for: ega, ena, encode, geo, ncbi_datasets.describe_datasetDescribe a study/dataset by native accession, with linked entities.
Available for: ega, ena, encode, geo, ncbi_datasets.list_filesList files of a study/dataset with format, size, checksums, index and readiness.
Available for: ega, ena, encode, geo, local, ncbi_datasets, s3.list_samplesList samples of a study/dataset as supplied by the source.
Available for: ega, ena, encode, geo, ncbi_datasets.get_sample_metadataGet one sample's metadata and phenotype values exactly as supplied by the source.
Available for: ega, ena, encode, geo, ncbi_datasets.fetch_fileStart a bounded download of a file (and index) to the local work dir. Returns a transfer job; files above the default limit need budget_bytes.
Available for: default.get_transfer_statusGet progress/result of a transfer started by fetch_file.
Available for: default.cancel_transferCancel a running transfer.
Available for: default.get_readsAlignments overlapping an interval from indexed BAM/CRAM. Flag filters follow samtools -f/-F. CRAM needs a matching reference unless self-contained.
Available for: bam, cram.get_coverageRead depth over an interval from indexed BAM/CRAM (default excludes UNMAP, SECONDARY, QCFAIL, DUP, like samtools depth).
Available for: bam, cram.get_pileupPer-position base counts over an interval from indexed BAM/CRAM.
Available for: bam, cram.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.
