- MCP serves as a standardized gateway that lets AI agents act across existing APIs and services, enabling multi‑step, real‑world workflows.
- Block reports transforming an internal MCP deployment into a company‑wide platform, with 60% of its roughly 10,000 employees using it weekly to automate tasks.
- Block cites MCP‑powered agents accelerating fraud analysis and completing an evaluation of 81,000 sales leads with recommendations in about one hour.
- Engineering guidance warns that 1:1 conversions of human‑centric APIs into MCP tools confuse agents, advocating goal‑driven, flow‑based tools such as a single findCheapestDirectFlights action.
- Operators highlight open source collaboration and enterprise controls—authentication, audit trails and lineage—as core to safely running MCP in production.
