AI Agent Portability: How to Switch Models Without Rebuilding Your Agents

AI agent portability depends on separating model providers from agent logic, tools, memory, orchestration, and governance so organizations can evaluate or replace LLMs with configuration changes, prompt validation, and regression testing rather than extensive rebuilds. The Model Context Protocol (MCP) is presented as a vendor-neutral standard for reusable tool and data integrations across compatible clients, while external memory stores, model abstraction layers, declarative agent specifications, and multi-model routing can reduce framework dependence and optimize costs. The text emphasizes that portability alone does not ensure quality, requiring systematic evaluation of accuracy, task completion, latency, tool efficiency, and cost, while noting Snowflake’s reported improvement from a plain-text data ontology. It also argues that centralized security, audit logging, scoped credentials, data-loss-prevention policies, and observability are necessary to maintain consistent controls as models and frameworks change. MintMCP is described as providing MCP and agent gateways intended to govern tool access, agent identities, permissions, memory, monitoring, and compliance across multi-model deployments.
