Implementation Reference
- src/jira-client.ts:80-85 (handler)Core implementation of the jira_assign_issue tool: calls Jira REST API to assign or unassign an issue by PUT to /issue/{issueKey}/assignee with {name: username} (null to unassign).
async assignIssue(issueKey: string, username: string | null): Promise<void> { await this.request<void>(`/issue/${issueKey}/assignee`, { method: "PUT", body: JSON.stringify({ name: username }), }); } - src/index.ts:1004-1017 (handler)MCP CallToolRequestHandler switch case for 'jira_assign_issue': validates arguments with AssignIssueSchema and delegates to jiraClient.assignIssue, returns success message.
case "jira_assign_issue": { const { issueKey, assignee } = AssignIssueSchema.parse(args); await jiraClient.assignIssue(issueKey, assignee); return { content: [ { type: "text", text: assignee ? `Issue ${issueKey} assigned to ${assignee}` : `Issue ${issueKey} unassigned`, }, ], }; } - src/index.ts:82-88 (schema)Zod input schema definition for the jira_assign_issue tool used for validation in the handler.
const AssignIssueSchema = z.object({ issueKey: z.string().describe("The Jira issue key"), assignee: z .string() .nullable() .describe("Username to assign (null to unassign)"), }); - src/index.ts:309-323 (registration)Tool registration entry returned by ListToolsRequestHandler, including name, description, and JSON input schema.
