# Best Cloud Infrastructure Tools for AI Agents (2026)

Hosting, CDN, DNS, serverless

| # | Tool | Grade | Score | Biggest Friction |
|---|------|-------|-------|-----------------|
| 1 | Cloudflare | B+ | 7.46 | Lack of an OpenAPI specification and machine-readable capability files (llms.txt/agents.json) prevents agents from autonomously discovering API capabilities and must rely on embedded documentation knowledge. |
| 2 | AWS | B+ | 7.42 | The absence of a unified OpenAPI specification and the fragmentation across 200+ services with inconsistent API patterns make discoverability and agent onboarding unnecessarily difficult compared to purpose-built API-first platforms. |
| 3 | Fastly | B+ | 7.06 | Absence of an OpenAPI specification combined with no MCP server support limits automated agent discoverability and integration, requiring manual API exploration and custom integration code. |
| 4 | Google Cloud | B+ | 7.04 | Absence of published OpenAPI specifications and MCP server support makes it difficult for AI agents to autonomously discover available operations and their schemas without manual integration work. |
| 5 | Upstash | B | 6.7 | The absence of an OpenAPI specification and /well-known/llms.txt severely limits agent discoverability and autonomous integration, requiring manual documentation review and SDK dependency rather than specification-driven access. |
| 6 | Linode | B | 6.52 | The absence of an OpenAPI specification and machine-readable API documentation (no llms.txt or agents.json) forces agents to rely entirely on human-readable docs, creating a significant discovery and integration friction point. |
| 7 | DigitalOcean | B | 6.4 | Absence of an OpenAPI specification and MCP server documentation makes it difficult for agents to discover and validate API capabilities without manual integration work. |
| 8 | Vultr | B | 6.18 | The absence of an OpenAPI specification and MCP server, combined with robots.txt blocking agents, creates significant barriers to autonomous agent discovery and integration despite Vultr's mature REST API and SDKs. |
| 9 | Hetzner | B | 6.06 | Absence of OpenAPI specification and agent-discovery standards (llms.txt, agents.json, MCP server) prevents automated agent integration despite solid underlying REST API and SDK coverage. |
| 10 | Azure | C+ | 5.94 | The absence of an OpenAPI specification and MCP server makes it extremely difficult for agents to discover, understand, and safely interact with Azure's hundreds of services without human guidance. |
