To safely change MCP tool scope, audit the proposed tool-surface modification for scope, profile, registration, and contract impact before merging. This validates declared scope, profile availability, side effects, and idempotency to keep client interactions safe.

MCP tool registration integrity verifies static registration in the startup path and ensures discovery metadata stays aligned. It enforces fail-closed defaults, communication-tool discipline, and audit-event requirements to maintain explicit contracts between clients and the deployment.

You need to audit MCP tool-surface changes when introducing a new tool, changing a tool's scope from read to write, or adjusting which profiles can access an existing capability. This applies to statically registered MCP servers including social, memory, communication, and identity workflows.

Yes, you can safely add, modify, or remove tools in statically registered MCP servers by auditing the changes. The audit validates declared scope, profile availability, side effects, idempotency, and discovery metadata consistency before you ship the update.

Changing MCP tool profiles requires validating profile availability and enforcing fail-closed defaults to maintain contract safety. Limitations arise if discovery metadata becomes inconsistent or if communication-tool discipline and audit-event requirements are not met during modification.
