handler: async ({ eventId, subject, startDate, startTime, endDate, endTime, location, body, calendar }) => { try { const result = await updateEvent(eventId, subject, startDate, startTime, endDate, endTime, location, body, calendar); return { content: [ { type: 'text', text: result.success ? `Event updated successfully` : `Failed to update event` } ] }; } catch (error) { return { content: [ { type: 'text', text: `Error updating event: ${error.message}` } ], isError: true }; } } - src/outlookTools.js:294-335 (schema)Input schema for the 'update_event' tool, defining all parameters with types, descriptions, and required fields.

export async function updateEvent(eventId, subject, startDate, startTime, endDate, endTime, location, body, calendar) { return executeScript('updateEvent', { eventId, subject, startDate, startTime, endDate, endTime, location, body, calendar }); } - src/index.js:66-95 (registration)MCP server request handler for calling any tool (including 'update_event') by looking up in the tool registry and invoking its handler.
this.server.setRequestHandler(CallToolRequestSchema, async (request) => { const { name, arguments: args } = request.params; // Find the requested tool const tool = this.tools[name]; if (!tool) { throw new McpError( ErrorCode.MethodNotFound, `Tool not found: ${name}` ); } try { // Call the tool handler return await tool.handler(args); } catch (error) { console.error(`Error executing tool ${name}:`, error); return { content: [ { type: 'text', text: `Error executing tool ${name}: ${error.message}`, }, ], isError: true, }; } });
