Model Context Protocol: Set Tool Permissions Before Connection

Connecting an agent to tools changes what the product can do and what can go wrong. Before adding Model Context Protocol integration, define the smallest useful action and its permission boundary.

Use Least Privilege

Give the agent only the data and tools required for the first workflow. Separate read actions from actions that change records, send messages, or trigger payments. Make approvals explicit and log activity so the team can investigate unexpected behaviour.

Prove One Controlled Workflow

Test a narrow scenario with representative data, failures, and a human fallback. AI proof-of-concept scoping helps teams test capability without exposing every system at once. Revisit permissions as evidence and user needs change.
