ACMG/AMP classification
What does this variant mean? Review its identity and evidence
Start with one public variant expression. Folklore Clinical Variant Interpretation MCP resolves the identity, returns automated ACMG/AMP decision support and keeps the evidence, provenance and limitations attached to the result.
For case-based VCF analysis and qualified review, continue with the Folklore variant classification workflow.

Inspect the current exact variantAlready have a ClinVar, Ensembl or publication record?
Use the exact public HGVS, rsID or verified GRCh38 allele from the record, preserving transcript versions. A gene name, phenotype or paper title alone is not a variant identity. Folklore resolves the supported allele and returns automated classification with available evidence and provenance.
Read submitted ClinVar assertions separately from the automated classification. When publications are requested, use the verified identity for variant literature search; a paper association does not establish pathogenicity. Missing evidence and ambiguous identities remain explicit.
A reviewable classification workflow
A useful agent workflow must do more than produce a label. It should preserve the normalized variant identity, applied criteria, available source evidence, data versions and limitations so a qualified professional can review the path to the result.
- Resolve the public variant expression on GRCh38.
- Stop if resolution is ambiguous instead of choosing an allele.
- Report the automated classification and applied criteria exactly as returned.
- Separate available, unavailable and absent evidence.
- Keep the professional-review boundary visible.
Machine interface
Call search_variant_evidence or use the classify_germline_variant workflow prompt. The public endpoint is read-only and requires no account or API key.
Public scientific boundary
Folklore Clinical Variant Interpretation MCP accepts public gene, disease and single-variant queries. Do not send patient, phenotype, family, segregation or private case data. Results are automated decision support for qualified professional review, not a diagnosis or treatment recommendation.
