An example from the marker panel

What does the file
say about caffeine?

See the gene, rsID, genotype, and the panel’s interpretation together.

This synthetic sample carries CA at rs762551. The panel reads it as intermediate. One marker is a limited association, not a prediction of how a person will feel.

Ask about a result.
Keep the source local.

Connect the MCP server, then ask your agent a question about the report.

With a cloud model, the derived results it reads go to that provider. Use a local model to keep that conversation local too.

Example question: “What does my report say about caffeine?”

Actual lookup("rs762551") output for this sample:
{ "gene": "CYP1A2", "genotype": "CA",
  "interpretation": "intermediate" }

Tool output is real. The example question is illustrative; no model conversation is simulated.
