Connect Folklore Clinical Variant Interpretation MCP to your AI client

Folklore Clinical Variant Interpretation MCP is the official public, read-only MCP server from Helena Bioinformatics. It provides supported GRCh38 germline variant interpretation with structured Folklore evidence, automated ACMG/AMP decision support, transparent provenance and related scientific literature. It does not provide patient diagnoses or treatment recommendations, and its results require review by a qualified genetics professional.

Connection contract

Use Streamable HTTP. Folklore does not require an account, API key or OAuth flow.

Direct client connections

Every client below reaches the same endpoint and tool. A tested custom connection means that Folklore was connected in that client. It does not mean the provider has approved a public directory listing.

ChatGPT

Tested custom app

Create a custom MCP app and use the Folklore endpoint. No authentication fields are required.

Claude

Tested custom connector

Add a custom connector with the Folklore endpoint. The connection does not require an account or API key.

Codex and Cursor

Direct HTTP configuration

Add a server named folklore with the url field shown below.

VS Code

Direct HTTP configuration

Add a server named folklore with type http and the Folklore endpoint as its url.

Gemini CLI

Direct HTTP configuration

Add a server named folklore in the Gemini CLI MCP settings, select HTTP transport and use the Folklore endpoint.

Perplexity, Grok and Windsurf

Remote connector configuration

Use the same endpoint in the client remote MCP or custom connector settings. Select Streamable HTTP when the client asks for a transport.

Verified public listings

These pages were publicly reachable when this guide was reviewed on 13 August 2026. The Official MCP Registry is the canonical machine-readable publication source. Aggregator health labels do not replace the Folklore health and readiness checks.

Submitted and under review

Submission is recorded separately from publication. The links below show the durable public review item where one exists. ChatGPT and Claude directory submissions are complete, but public directory approval has not been independently verified. Smithery publication is deferred.

Ask a bounded question

Example: Use Folklore to classify ENST00000226413.5:c.317A>G under ACMG/AMP and summarize the evidence, provenance and limitations.

Supported input includes GRCh38 coordinates, selected genomic, coding and protein HGVS, SPDI and rsID for one nuclear germline SNV or simple indel smaller than 50 base pairs. Ambiguous expressions return candidates for the user to choose.

Clinical boundary

Folklore returns variant-level decision support for qualified genetics professionals. It accepts no patient, phenotype, family, segregation or case context. The automated classification is not a diagnosis, treatment recommendation or standalone clinical report.

A qualified professional must review the evidence and confirm clinically significant findings before clinical use.
