Implementation Reference
- The core handler function for the linear_createIssue tool. It validates the input arguments using isCreateIssueArgs type guard and delegates the creation to LinearService.createIssue.export function handleCreateIssue(linearService: LinearService) { return async (args: unknown) => { try { if (!isCreateIssueArgs(args)) { throw new Error('Invalid arguments for createIssue'); } return await linearService.createIssue(args); } catch (error) { logError('Error creating issue', error); throw error; } }; }
- The tool definition (schema) for linear_createIssue, specifying input parameters (e.g., title, teamId required) and output structure.export const createIssueToolDefinition: MCPToolDefinition = { name: 'linear_createIssue', description: 'Create a new issue in Linear', input_schema: { type: 'object', properties: { title: { type: 'string', description: 'Title of the issue', }, description: { type: 'string', description: 'Description of the issue (Markdown supported)', }, teamId: { type: 'string', description: 'ID of the team the issue belongs to', }, assigneeId: { type: 'string', description: 'ID of the user to assign the issue to', }, priority: { type: 'number', description: 'Priority of the issue (0 = No priority, 1 = Urgent, 2 = High, 3 = Normal, 4 = Low)', }, projectId: { type: 'string', description: 'ID of the project the issue belongs to', }, cycleId: { type: 'string', description: 'ID of the cycle to add the issue to', }, estimate: { type: 'number', description: 'The estimated complexity/points for the issue', }, dueDate: { type: 'string', description: 'The date at which the issue is due (YYYY-MM-DD format)', }, labelIds: { type: 'array', items: { type: 'string' }, description: 'IDs of the labels to attach to the issue', }, parentId: { type: 'string', description: 'ID of the parent issue (to create as a sub-task)', }, subscriberIds: { type: 'array', items: { type: 'string' }, description: 'IDs of the users to subscribe to the issue', }, stateId: { type: 'string', description: 'ID of the workflow state for the issue', }, templateId: { type: 'string', description: 'ID of a template to use for creating the issue', }, sortOrder: { type: 'number', description: 'The position of the issue in relation to other issues', }, }, required: ['title', 'teamId'], }, output_schema: { type: 'object', properties: { id: { type: 'string' }, identifier: { type: 'string' }, title: { type: 'string' }, url: { type: 'string' }, }, }, };
