OpenAI SDK with MCP: build mcp-enabled apps with ChatGPT integration

The Model Context Protocol (MCP) is presented as an open standard for connecting OpenAI models and other AI platforms to external systems such as file systems, databases, APIs, and enterprise tools through standardized, schema-defined tools. OpenAI’s Agents SDK supports MCP through local stdio, remote SSE, and Streamable HTTP transports, automating tool discovery, invocation, and result handling, while the Responses API can use hosted remote MCP tools. The guide demonstrates building file-system, database, GitHub, and custom FastMCP integrations, along with applying static or dynamic tool filters, approval workflows, prompts, caching, and connection reuse to manage capabilities, security, and performance. It argues that local server deployments create operational risks involving credential distribution, process management, limited observability, and weak production boundaries, and presents MintMCP as a gateway-based alternative offering centralized deployment, OAuth and SSO authentication, curated virtual tool servers, audit logging, monitoring, policy enforcement, and compliance-oriented controls for enterprise environments.
