model context protocol adoption changes vendor boundaries

Teams are increasingly adopting shared context and tool interface patterns to connect models with internal systems, reducing one-off integration glue and vendor-specific coupling (Anthropic MCP).

context shift

The interface layer is becoming a product surface. Instead of rebuilding tool adapters per model, teams define stable context contracts and swap model providers behind them.

second order impact

• Procurement power shifts toward teams that own interface definitions.
• Vendor switching cost drops when tool contracts are portable.
• Security review gets simpler with fewer bespoke connectors.

decision boundary

This only compounds if interface governance is versioned and tested. Loose conventions recreate lock-in under a different name.

my take

Whoever owns the context layer controls long-term leverage. Model quality still matters, but interface ownership compounds faster.
