Implementation Reference

• operations/issues.ts:135-168 (handler)

  The main handler function that implements the delete_issue tool logic: fetches issue node_id then deletes via GitHub GraphQL API.

  export async function deleteIssue(owner: string, repo: string, issue_number: number) {
    // Bước 1: Lấy node_id (GraphQL ID) của issue
    const issue = await getIssue(owner, repo, issue_number) as { node_id: string };
  
    if (!issue || !issue.node_id) {
      throw new Error(`Issue #${issue_number} not found or cannot be accessed`);
    }
  
    // Bước 2: Sử dụng GraphQL API để xóa issue
    const mutation = `
      mutation DeleteIssue($issueId: ID!) {
        deleteIssue(input: { issueId: $issueId }) {
          clientMutationId
          repository {
            id
            name
          }
        }
      }
    `;
  
    const variables = {
      issueId: issue.node_id
    };
  
    const result = await graphqlRequest(mutation, variables);
  
    return {
      success: true,
      issue_number: issue_number,
      repository: `${owner}/${repo}`,
      ...result.data.deleteIssue
    };
  }

• operations/issues.ts:57-61 (schema)

  Zod schema defining the input parameters for the delete_issue tool.

  export const DeleteIssueSchema = z.object({
    owner: z.string(),
    repo: z.string(),
    issue_number: z.number(),
  });

• index.ts:210-213 (registration)

  Tool registration in the list of tools returned by ListToolsRequestHandler.

  {
    name: "delete_issue",
    description: "Delete an issue from a GitHub repository using GraphQL API",
    inputSchema: zodToJsonSchema(issues.DeleteIssueSchema),

• index.ts:490-496 (handler)

  Dispatcher case in the main CallToolRequestHandler that parses arguments and calls the deleteIssue function.

  case "delete_issue": {
    const args = issues.DeleteIssueSchema.parse(request.params.arguments);
    const result = await issues.deleteIssue(args.owner, args.repo, args.issue_number);
    return {
      content: [{ type: "text", text: JSON.stringify(result, null, 2) }],
    };
  }
