Arceo, the pre-flight check for AI agents

Field notes

Arceo combines a cost forecast with a capability-risk inventory: each callable action receives a per-call estimate and a blast weight, with irreversible actions counted more heavily. The page’s examples include a projected range of $2,410–$3,270, an 81/100 blast-radius score, and a chain in which separate support and operations agents collectively send customer data outside the company. It says the analysis is read-only and can examine Anthropic SDK, OpenAI, MCP, or public GitHub-based agents.
