Passive Cost Memory for Agent Development

Created By
RaleighSF2 months ago
Burnwatch detects every paid service in your project, tracks spend across 14 AI-native tools (Anthropic, OpenAI, Vercel, Supabase, Stripe, Scrapfly, Browserbase, and more), and exposes real-time cost data via MCP tools — so any LLM can factor budget into its recommendations. Four tools: get_spend_brief (full project spend overview), get_service_spend (single service deep dive with gotchas and alternatives), detect_paid_services (scan any project), list_registry_services (browse the registry). Zero dependencies. Works with Claude Code, Cursor, or any MCP-enabled client.
