Implementation Reference
- src/tools/regional-conditions.ts:32-68 (handler)The handler function executing the tool logic: validates region, fetches active events from DriveBC API filtered by region and optional type/limit, formats and returns the list or error messages.
export async function handleRegionalConditions(args: { region: string; eventType?: EventType; limit?: number; }): Promise<string> { try { const regionId = findRegionId(args.region); if (!regionId) { const validRegions = Object.keys(BC_REGIONS).join(', '); return `Invalid region "${args.region}". Valid regions are: ${validRegions}`; } const params: EventQueryParams = { status: 'ACTIVE', area_id: regionId, limit: args.limit ?? 50, }; if (args.eventType) { params.event_type = args.eventType; } const events = await getEvents(params); if (events.length === 0) { return `No current events found for ${args.region} region.`; } return `Regional Conditions for ${args.region}\n\n${formatEventList(events)}`; } catch (error) { if (error instanceof Error) { return `Error fetching regional conditions: ${error.message}`; } return 'Error fetching regional conditions: Unknown error'; } } - Tool definition with name, description, and input schema for parameters: region (required), eventType (optional enum), limit (optional 1-500).
export const regionalConditionsTool = { name: 'get_regional_conditions', description: 'Get road conditions and events for a specific BC region.

server.setRequestHandler(ListToolsRequestSchema, async () => { return { tools: [ highwayConditionsTool, regionalConditionsTool, roadClosuresTool, weatherAlertsTool, ], }; }); - src/index.ts:56-75 (registration)Dispatches calls to the get_regional_conditions tool by invoking handleRegionalConditions in the MCP CallToolRequestHandler switch statement.
