Best AI agent integration platforms to consider in 2025

AI agent integration platforms are essential for connecting agents to external APIs with enhanced reliability, latency management, scalability, and observability. These platforms offer infrastructure and tools to manage authentication, execute tools, enforce permissions, and log activities, enabling agents to make deterministic tool calls with clear inputs and outputs. Key features to look for include broad API coverage, extensibility, low overhead, scalable runtime, robust authentication, and deep real-time observability. Notable platforms include Nango, which offers a code-first experience and supports over 500 APIs; Arcade, which focuses on the Model Context Protocol (MCP) for tool calling with advanced testing; and Workato, which provides an enterprise iPaaS with strong governance, auditing, and centralized management for internal tool use. Selecting the right platform depends on specific needs such as deep control, performance, visibility, and whether the focus is on product integrations or internal use cases.
