api record

Population genetics over gnomAD. dataset (gnomad_r4 default, GRCh38) and reference_genome are distinct, coherent parameters — keep the build aligned with ensembl coordinates; both are echoed in output. Per-ancestry allele frequencies are never collapsed to a single global AF. An absent variant is uninterpretable without gnomad_get_coverage — confirm the position is callable before concluding true absence (the gnomad_variant_triage prompt chains this). gnomad_list_gene_variants and gnomad_search_clinvar stage large results on a DataCanvas (set CANVAS_PROVIDER_TYPE=duckdb) queryable via…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • gnomad_get_variant unknown never probed

    Fetch the full gnomAD population record for one or more variants — allele count/number/frequency overall and broken down per genetic-ancestry group, homozygote and hemizygote counts, quality flags, transcript consequence, in-silico predictor scores, and joined ClinVar clinical significance. The "how common, is it benign" answer in one call. Accepts a batch of up to 25 IDs (chrom-pos-ref-alt or rsID) with per-item partial success: a malformed or absent ID lands in failed[] without failing the others. An empty found[] for a well-formed ID means the variant is not in the chosen dataset — pair with gnomad_get_coverage to confirm the position is callable before concluding true absence.

  • gnomad_get_gene_constraint unknown never probed

    Fetch gnomAD loss-of-function constraint for a gene — pLI (probability of LoF intolerance; >0.9 intolerant), LOEUF (oe_lof_upper, the headline metric; <0.6 intolerant in v4, <0.35 in v2) plus its lower bound, observed/expected ratios for LoF, missense, and synonymous variation, and the three Z-scores. This is the orthogonal axis to allele frequency: a loss-of-function variant matters far more in a gene intolerant to being broken. Accepts an HGNC symbol (PCSK9) or an Ensembl gene ID (ENSG00000169174). Many genes have null constraint (sparse upstream) — null fields are reported as such, never fabricated. v4 constraint is flagged beta by the gnomAD team; constraint_flags surfaces any caveats. Echoes the effective dataset and reference build. Data source: gnomAD (Broad Institute) — https://gnomad.broadinstitute.org/

  • gnomad_list_gene_variants unknown never probed

    List every gnomAD variant in a gene, transcript, or region with allele frequencies and predicted consequences, optionally filtered to one consequence class (lof, missense, synonymous, other) and/or a maximum allele frequency. The full result is staged on a DataCanvas table named gene_variants and an inline preview is returned alongside canvas_id and table_name — run gnomad_dataframe_query against them to rank by AF, count by consequence, or group across the complete set rather than the preview. When the canvas is disabled (CANVAS_PROVIDER_TYPE != duckdb) the tool returns a capped inline preview with spilled=false and canvas_id empty; the SQL path is then unavailable. Supply exactly one of gene, transcript_id, or region. Echoes the effective dataset and build. Data source: gnomAD (Broad Institute) — https://gnomad.broadinstitute.org/

  • gnomad_get_coverage unknown never probed

    Fetch gnomAD sequencing-coverage summary across a gene, transcript, or region — mean and median read depth, plus the mean fraction of samples covered at each depth threshold (1× through 100×), separated by exome and genome track. Use this to disambiguate a true absent variant from an uncallable position: a variant missing from a well-covered region is informative, while one missing from a poorly-covered region is not. Supply exactly one of gene, transcript_id, or region. The optional coverage_source narrows to one track; by default both available tracks are returned. Echoes the effective dataset and build.

  • gnomad_search_clinvar unknown never probed

    Search ClinVar (NCBI E-utilities) for a gene and return its classified variants — clinical significance, review status with a 0–4 star rating, associated conditions, molecular consequences, and submission counts — turning the variant-level significance gnomAD joins into a gene-panel curation view. Optionally filter by clinical_significance (e.g. pathogenic) and a minimum star rating. The full set is staged on a DataCanvas table named clinvar_variants with an inline preview; query it with gnomad_dataframe_query to rank or count across the complete set. Keyless, but honors NCBI_API_KEY for a higher rate limit. When the canvas is disabled the tool returns a capped inline preview with spilled=false. Credit: ClinVar, NCBI.

Use the canvas_id and table_name those tools returned to rank by allele frequency, group by consequence class, count loss-of-function variants, or filter the full set the inline preview only sampled.

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
