Implementation Reference

• src/tools/submitPresentation.ts:9-210 (handler)

  The primary handler function implementing the submit_presentation tool. Validates input using the schema, evaluates credentials against the presentation definition via API, submits the presentation, analyzes fulfillment status, and returns comprehensive results with markdown formatting.
  export async function submitPresentation(args: unknown): Promise<CallToolResult> { const validation = validateAndSanitizeInput( TOOL_SCHEMAS.submit_presentation, args, 'submit_presentation' ); if (!validation.success) { return createValidationErrorResult(validation.error!); } const data = validation.data!; const startTime = Date.now(); try { // First evaluate which credentials match the presentation definition const evaluationResponse = await fetch(`${process.env.HIVEAUTH_API_BASE_URL}/api/presentation/evaluate`, { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ presentationDefinition: data.presentationDefinition, credentials: data.credentials }) }); if (!evaluationResponse.ok) { const errorText = await evaluationResponse.text(); throw new Error(`Evaluation failed (${evaluationResponse.status}): ${errorText}`); } const evaluationResult = await evaluationResponse.json(); // Check if evaluation was successful if (!evaluationResult.success || !evaluationResult.data) { return { content: [ { type: 'text', text: `❌ **Presentation Submission Failed** **Error:** Credentials do not satisfy presentation definition requirements **Evaluation Result:** ${JSON.stringify(evaluationResult, null, 2)} **Resolution:** Ensure provided credentials match the input descriptors and constraints specified in the presentation definition.` } ], isError: true }; } // Now submit the presentation with the matching credentials const submissionResponse = await fetch(`${process.env.HIVEAUTH_API_BASE_URL}/api/presentation/submit`, { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ presentationDefinition: data.presentationDefinition, credentials: data.credentials, holderDid: data.holderDid, challenge: data.challenge, domain: data.domain }) }); if (!submissionResponse.ok) { const errorText = await submissionResponse.text(); throw new Error(`Submission failed (${submissionResponse.status}): ${errorText}`); } const submissionResult = await submissionResponse.json(); const processingTime = Date.now() - startTime; if (!submissionResult.success) { return { content: [ { type: 'text', text: `❌ **Presentation Submission Failed** **Error:** ${submissionResult.error || 'Unknown submission error'} **Processing Time:** ${processingTime}ms **Evaluation Results:** ${JSON.stringify(evaluationResult.data, null, 2)} **Debug Info:** Check that all required credentials are present and valid.` } ], isError: true }; } // Analyze the submitted presentation const presentation = submissionResult.data.presentation; const presentationSubmission = submissionResult.data.presentationSubmission; const credentialCount = Array.isArray(presentation.verifiableCredential) ? presentation.verifiableCredential.length : 1; const inputDescriptorIds = data.presentationDefinition.input_descriptors.map(desc => desc.id); const submittedDescriptors = presentationSubmission?.descriptor_map?.map((desc: any) => desc.id) || []; const fulfillmentStatus = inputDescriptorIds.map(id => ({ inputDescriptorId: id, fulfilled: submittedDescriptors.includes(id), descriptor: data.presentationDefinition.input_descriptors.find(desc => desc.id === id) })); const allRequirementsMet = fulfillmentStatus.every(status => status.fulfilled); return { content: [ { type: 'text', text: `✅ **Presentation Submission Successful** **Submission Status:** ${allRequirementsMet ?

• src/schemas/toolSchemas.ts:151-157 (schema)

  Zod schema defining the input structure and validation for the submit_presentation tool, including presentationDefinition, credentials array, and optional holderDid, challenge, domain fields.
  export const SubmitPresentationInputSchema = z.object({ presentationDefinition: PresentationDefinitionSchema, credentials: z.array(CredentialSchema).min(1, 'At least one credential is required'), holderDid: z.string().optional().describe('DID of the presentation holder'), challenge: z.string().optional().describe('Challenge for the presentation proof'), domain: z.string().optional().describe('Domain for the presentation proof') });
• src/utils/schemaConverter.ts:66-70 (registration)

  Tool definition registration in TOOL_DEFINITIONS array, which is used by createMCPTools() to generate the MCP Tool object with name, description, and JSON schema for the MCP server.
  { name: 'submit_presentation', description: 'Create and submit verifiable presentations from evaluation results. Builds presentations that satisfy DIF PEX v2.0 requirements with holder binding and proof generation.', inputSchema: TOOL_SCHEMAS.submit_presentation },
• src/index.ts:113-114 (registration)

  Dispatch registration in the MCP server's CallToolRequest handler switch statement, routing submit_presentation calls to the submitPresentation handler function.
  case 'submit_presentation': return await submitPresentation(args);
• src/schemas/toolSchemas.ts:188-188 (schema)

  Maps the SubmitPresentationInputSchema to 'submit_presentation' key in the TOOL_SCHEMAS object used across the codebase for schema lookup.
  submit_presentation: SubmitPresentationInputSchema,
