Strengths	+ Open protocol over HTTP + Sub-cent settlement via stablecoins + Backed by Coinbase + open community	+ Broad framework coverage across OpenAI Agents SDK, LangChain, CrewAI, and Vercel AI SDK + Hosted remote MCP server with OAuth plus a local MCP option + Restricted API keys (rk_*) scope what agents are allowed to do + Backed by the Agentic Commerce Protocol open standard from Stripe, OpenAI, and Meta
Tradeoffs	− Crypto rails add operational and compliance complexity	− Requires a Stripe account, with standard Stripe processing fees on transactions − Parts of the agent tooling are in beta and access-gated − Stripe recommends sandbox testing and evals because agent behavior is non-deterministic
