Useful MCP integration begins by defining the business task, source systems, allowed actions, evidence requirements and approval points. The protocol then becomes a controlled interface, not an open-ended shortcut.
Least access should be designed early
Agents should see only the tools, records and actions required for the workflow. Splexion maps access patterns, identities, scopes, logging and escalation before production use.
Integration needs reviewable behaviour
A governed MCP pattern should make it possible to inspect what an agent requested, what tool responded, what evidence was used and where human approval changed the outcome.
