Input Schema (JSON Schema)

Implementation Reference

• src/tools/delete-worklog.ts:9-71 (handler)

  The primary handler function implementing the delete_worklog tool logic. It validates input implicitly via type, calls TempoClient.deleteWorklog, handles errors with user-friendly messages, and returns MCP CallToolResult.
  export async function deleteWorklog( tempoClient: TempoClient, input: DeleteWorklogInput ): Promise<CallToolResult> { try { const { worklogId } = input; // First, try to get the worklog details before deletion (for confirmation) let worklogDetails = ''; try { // Note: We could get worklog details first, but the Tempo API might not have a direct endpoint // for getting a single worklog. In practice, this would require getting all worklogs and filtering. // For simplicity, we'll proceed with deletion and provide the ID in the confirmation. worklogDetails = `Worklog ID: ${worklogId}`; } catch (detailError) { // If we can't get details, that's okay - we'll still try to delete worklogDetails = `Worklog ID: ${worklogId} (details unavailable)`; } // Attempt to delete the worklog await tempoClient.deleteWorklog(worklogId); // Format success response let displayText = `## Worklog Deleted Successfully\n\n`; displayText += `The worklog has been permanently removed from Tempo.\n\n`; displayText += `**Details:**\n`; displayText += `- ${worklogDetails}\n`; displayText += `- Deleted at: ${new Date().toISOString()}\n\n`; displayText += `⚠️ **Note:** This action cannot be undone. The worklog and all associated time entries have been permanently removed from your timesheet.\n`; return { content: [ { type: "text", text: displayText } ], isError: false }; } catch (error) { let errorMessage = error instanceof Error ? error.message : String(error); // Provide more helpful error messages for common issues if (errorMessage.includes('not found')) { errorMessage = `Worklog with ID '${input.worklogId}' was not found. It may have already been deleted or the ID may be incorrect.`; } else if (errorMessage.includes('Authentication failed')) { errorMessage += `\n\nTip: Check your Personal Access Token (PAT) in the TEMPO_PAT environment variable.`; } else if (errorMessage.includes('Access forbidden')) { errorMessage += `\n\nTip: Make sure you have permission to delete this worklog. You can typically only delete your own worklogs.`; } return { content: [ { type: "text", text: `## Error Deleting Worklog\n\n**Worklog ID:** ${input.worklogId}\n\n**Error:** ${errorMessage}\n\n**Troubleshooting:**\n- Verify the worklog ID is correct\n- Check that the worklog exists and belongs to you\n- Ensure you have proper permissions in Tempo\n- Confirm your authentication credentials are valid` } ], isError: true }; } }
• src/types/mcp.ts:39-41 (schema)

  Zod schema defining the input structure for the delete_worklog tool: requires a 'worklogId' string.
  export const DeleteWorklogInputSchema = z.object({ worklogId: z.string().min(1, "Worklog ID is required"), });
• src/index.ts:177-190 (registration)

  MCP tool registration in ListToolsRequestHandler: defines name, description, and input schema for delete_worklog.
  { name: TOOL_NAMES.DELETE_WORKLOG, description: "Delete an existing worklog entry", inputSchema: { type: "object", properties: { worklogId: { type: "string", description: "Tempo worklog ID to delete", }, }, required: ["worklogId"], }, },
• src/index.ts:236-239 (registration)

  Tool execution dispatcher in CallToolRequestHandler: parses input using schema and invokes the deleteWorklog handler.
  case TOOL_NAMES.DELETE_WORKLOG: { const input = DeleteWorklogInputSchema.parse(args); return await deleteWorklog(tempoClient, input); }
• src/tools/index.ts:6-6 (helper)

  Re-export of the deleteWorklog handler from its implementation file, used by src/index.ts.
  export { deleteWorklog } from "./delete-worklog.js";
