Setup snapshot
git clone https://github.com/daveHylde/brreg-mcp-server.gitSetup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.
