Implementation Reference
- src/telemetry-service.ts:52-68 (handler)The primary handler function that fetches today's usage metrics from Prometheus using predefined PromQL queries over the last 1 day and constructs the UsageData object.
async getTodayUsage(): Promise<UsageData> { const startOfDay = this.getStartOfDay(); const now = new Date(); const queries = { tokens: `sum(increase(claude_code_token_usage_tokens_total[1d]))`, cost: `sum(increase(claude_code_cost_usage_USD_total[1d]))`, sessions: `sum(increase(claude_code_session_count_total[1d]))`, activeTime: `sum(increase(claude_code_active_time_seconds_total[1d]))`, linesOfCode: `sum(increase(claude_code_lines_of_code_count_total[1d]))`, commits: `sum(increase(claude_code_commit_count_total[1d]))`, editDecisions: `sum(increase(claude_code_code_edit_tool_decision_total[1d]))` }; const results = await this.executeQueries(queries); return this.buildUsageData(results); } - src/index.ts:46-52 (registration)Tool registration in the ListTools response, defining name, description, and empty input schema.
{ name: 'get_today_usage', description: 'Get total usage metrics for today (tokens, cost, sessions, activity)', inputSchema: { type: 'object', properties: {}, }, - src/index.ts:211-221 (handler)MCP CallToolRequest handler case that calls the telemetry service method and returns formatted text response.
case 'get_today_usage': { const usage = await this.telemetryService.getTodayUsage(); return { content: [ { type: 'text', text: this.formatUsageData('Today', usage), }, ], }; } - src/types.ts:27-35 (schema)TypeScript interface defining the structure of UsageData returned by the handler.
export interface UsageData { tokens: number; cost: number; sessions: number; activeTime: number; linesOfCode: number; commits: number; editDecisions: number; }
