AI Architecture Enablement

The tool boundary is explicit: MCP hosts broker calls, tool servers own access, and schema validation keeps unsafe data away from the agent core.

Env: Enterprise HubIngress: Corporate Gateway

Problem: I designed patterns for teams adopting MCP-style tools. The goal was to let agents call databases and APIs without exposing raw credentials or ownership boundaries.

Architecture Decision

Why I chose this design.

Short decision notes tied to the code or config that mattered.

Decision

ADR-04-MCP.md

I used MCP-style tool boundaries so teams can reuse agent capabilities without copying secrets or proprietary logic into every app.

# ADR-04: Model Context Protocol Adoption
## StatusAccepted
## ContextMulti-agent workflows need dynamic tool access, but directmodel-to-system integration creates duplicated security logic.
## DecisionWrap database connections, internal APIs, and calculators inseparate MCP-style tool servers. The agent runtime receivesschema-validated tool results, not raw system access.
## ConsequenceLatency may increase at the protocol boundary, but ownership,auditability, and reuse improve across teams.
