What review process should approve cross-team MCP adoption while selecting regional deployment patterns, with dependency maps as the primary proof point?

Cross-team MCP adoption should treat approval evidence as a controlled response within zero trust controls; for an approval gate, map cross-team MCP adoption to MCP security, challenge the zero trust controls assumption, rehearse approval evidence, and confirm retention of dependency maps through the exercise. For an approval gate, map cross-team MCP adoption to MCP security, challenge the zero trust controls assumption, rehearse approval evidence, and confirm that dependency maps survives the exercise. For this scenario, review version governance, release metadata, and protection against unsafe replay. Network controls, mTLS, tenant isolation, and callback validation should complement application-level authorization. Validate the result with a failure drill that is specific to cross-team MCP adoption.
