Implementation Reference
- src/index.ts:689-695 (handler)The main handler function for the 'get_transcript' tool. It parses the input arguments, makes a GraphQL request using the predefined query, and formats the response.
case "get_transcript": result = await makeGraphQLRequest(QUERIES.getTranscript, { transcriptId: args.transcript_id as string, referenceGenome: parseReferenceGenome((args.reference_genome as string) || "GRCh38"), }); formattedResult = result.data?.transcript || null; break; - src/index.ts:216-252 (schema)GraphQL query schema definition for fetching transcript details including location, gene info, and gnomAD constraint metrics.
getTranscript: ` query GetTranscript($transcriptId: String!, $referenceGenome: ReferenceGenomeId!) { transcript(transcript_id: $transcriptId, reference_genome: $referenceGenome) { transcript_id transcript_version reference_genome chrom start stop strand gene_id gene_symbol gene_version gnomad_constraint { exp_lof exp_mis exp_syn obs_lof obs_mis obs_syn oe_lof oe_lof_lower oe_lof_upper oe_mis oe_mis_lower oe_mis_upper oe_syn oe_syn_lower oe_syn_upper lof_z mis_z syn_z pLI } } } `, - src/index.ts:507-525 (registration)Tool registration in the ListTools handler, defining name, description, and input schema for validation.
