Best AI Agent Infrastructure Platforms for Cursor

TinyFish is a web infrastructure platform for developers and AI teams building agents and applications that need to access or operate across the web. The platform includes four connected product surfaces: 1. Search provides agent-optimized web search with current results structured for AI consumption. 2. Fetch extracts clean content from specified URLs and returns it as markdown, JSON, or HTML. It supports dynamic, JavaScript-heavy, and single-page application websites. 3. Browser provides managed cloud Chrome sessions, fingerprinting, session infrastructure, scaling, and browser management. 4. Web Agent takes a goal and a URL, navigates a website, works through filters and pagination, fills forms, authenticates when required, and returns the requested result. 5. Vault and Profiles support Web Agent workflows by securely handling credentials and identity for authenticated website operations. Together, these capabilities allow developers to move from web discovery and content retrieval into complete, multi-step web operations without assembling and maintaining separate infrastructure products.

KERNEL serves as a cloud-based browser infrastructure solution tailored for developers who create AI agents and automate web interactions. By offering managed browser sessions, it enables these agents to explore websites, engage with content, and execute tasks through programming rather than depending on traditional local browser configurations. The platform is optimized for production use, featuring persistent browser profiles, live session monitoring, recording, and replay functionalities, along with tools to oversee browser access effectively. Teams can seamlessly integrate their agent workflows using KERNEL's APIs, SDKs, and hosted MCP server, making it ideal for web research, data collection, and various activities that necessitate web engagement. Additionally, KERNEL offers various subscription options for individuals, startups, and large enterprises, each providing different levels of browser concurrency, usage credits, and access to advanced features like managed authentication, stealth mode, and region-specific browsers. Ultimately, KERNEL stands out as a comprehensive solution catering to a wide range of web automation needs.

Composio Instant serves as a cloud-based wallet that enables AI agents to access paid tools without the necessity for developers to subscribe to each service provider or individually configure API keys for every tool. By linking Instant to an agent session, developers can select the tools they wish to make available while utilizing a communal organization balance, with all transactions documented in execution logs. Each call deducts from this shared balance at a per-use fee, and newly registered developer organizations benefit from a one-time credit of $2 to get started. The platform offers a variety of services, such as web searching, data enrichment, web scraping, transcription, voice services, weather updates, and document processing. Developers can easily integrate by using Composio’s SDKs and MCP-compatible agent clients like Claude, ChatGPT, Codex, Cursor, Gemini CLI, Grok, and Visual Studio Code. Instant is specifically designed for developers and teams who are creating or managing AI agents that require immediate access to external services, thus streamlining the integration process. This functionality not only enhances efficiency but also allows for greater flexibility in the deployment of AI capabilities.

VideoDB serves as an advanced backend solution for AI agents, empowering them to perceive, interpret, and respond to audio and video content in real time. It acts as an intermediary between unprocessed media streams and the reasoning capabilities of agents, transforming ongoing streams into organized, searchable contextual data complete with actionable evidence. Our comprehensive See->Understand->Act process eliminates the need for a disjointed array of tools such as FFmpeg, vector databases, and transcription services by offering a single, programmable media framework. With the innovative "Indexes-as-code" feature, developers can derive insights from spoken language and visual elements with almost instantaneous response times. Supporting both Python and Node.js SDKs, VideoDB integrates smoothly with platforms like Claude, Cursor, and Codex through the Model Context Protocol (MCP). Its architecture prioritizes streaming, ensuring that your agents maintain continuous awareness of their environment instead of relying solely on fixed files. From creating an AI meeting assistant to enhancing camera intelligence or facilitating automated media editing, VideoDB delivers the essential perception framework required for a variety of applications. In doing so, it significantly enhances the capabilities of AI agents, allowing them to operate more effectively and responsively in dynamic settings.

NoMac offers cloud-based virtual machines running macOS on Apple silicon, designed specifically for iOS and macOS development. Each session comes equipped with macOS, Xcode, iOS simulator runtimes, and essential developer tools, allowing for seamless builds, testing, and simulator operations without needing a physical Mac. Developers and coding agents have the flexibility to manage their sessions via a browser desktop interface, CLI, SSH, HTTPS API, or a hosted Model Context Protocol (MCP) server. Their workflows encompass tasks such as app building and testing, operating the simulator, taking screenshots, signing applications, and preparing uploads for TestFlight. Every session operates on a new virtual machine, which is deleted once the session concludes, ensuring a clean environment each time. Users can keep their projects and build caches intact between sessions using an account drive. NoMac caters to iOS and macOS developers, including teams utilizing coding agents that require Xcode, even those working from Windows or Linux environments. The billing structure is based on a per-minute usage rate from prepaid credits, with a minimum charge of one minute and a cap on spending per session. Additionally, this model allows developers to efficiently manage their resources and optimize costs while maintaining access to the necessary tools for effective development.
