Implementation Reference
- The primary handler function for the 'linear_duplicateIssue' MCP tool. It validates the input arguments using a type guard and delegates to the LinearService.duplicateIssue method.
export function handleDuplicateIssue(linearService: LinearService) { return async (args: unknown) => { try { if (!isDuplicateIssueArgs(args)) { throw new Error('Invalid arguments for duplicateIssue'); } return await linearService.duplicateIssue(args.issueId); } catch (error) { logError('Error duplicating issue', error); throw error; } }; } - The tool schema definition specifying input (issueId) and output structures for 'linear_duplicateIssue'.
export const duplicateIssueToolDefinition: MCPToolDefinition = { name: 'linear_duplicateIssue', description: 'Duplicate an issue', input_schema: { type: 'object', properties: { issueId: { type: 'string', description: 'ID or identifier of the issue to duplicate (e.g., ABC-123)', }, }, required: ['issueId'], }, output_schema: { type: 'object', properties: { success: { type: 'boolean' }, originalIssue: { type: 'object', properties: { id: { type: 'string' }, identifier: { type: 'string' }, title: { type: 'string' }, }, }, duplicatedIssue: { type: 'object', properties: { id: { type: 'string' }, identifier: { type: 'string' }, title: { type: 'string' }, url: { type: 'string' }, }, }, }, }, }; - src/tools/handlers/index.ts:120-120 (registration)Registration of the 'linear_duplicateIssue' tool handler within the registerToolHandlers function.
linear_duplicateIssue: handleDuplicateIssue(linearService), - src/tools/type-guards.ts:380-389 (helper)Type guard function used by the handler to validate and type-check the input arguments for the tool.
export function isDuplicateIssueArgs(args: unknown): args is { issueId: string; } { return ( typeof args === 'object' && args !== null && 'issueId' in args && typeof (args as { issueId: string }).issueId === 'string' ); }
