Independent review. IonBin has no partnership with Cloudflare Workers and was not paid for this page. Our evaluation is our own, based on public documentation and our research. Product names are trademarks of their owners and are used for identification only. How disclosure works.

Cloudflare's developer platform: Workers (serverless code), R2 (object storage), D1 (SQL database), Workers AI (models on serverless GPUs) and the Agents SDK, including hosting remote MCP servers.

Best for

APIs, webhooks and small backends at the edge
Hosting your own remote MCP server or agent

Not for

Long-running servers that need a traditional VM

How to use it with AI

How Cloudflare Workers connects to each AI platform: native connector or MCP, API through code the agent writes, browser control, or file upload.

Platform	MCP / connector	API (agent-written code)	Browser	Upload / export
Claude (incl. Claude Code)	Confirmed Claude named as an OAuth client for Cloudflare's managed MCP servers Cloudflare Workers docs ↗Claude (incl. Claude Code) MCP docs ↗	Confirmed Claude (incl. Claude Code) can run code; Cloudflare Workers publishes an API. Claude (incl. Claude Code) docs ↗	Confirmed Claude Code with the Claude in Chrome extension (Chrome, Edge and other Chromium browsers) Claude (incl. Claude Code) browser docs ↗	Confirmed Export from Cloudflare Workers, then works on the files in your project; chat accepts attachments Claude (incl. Claude Code) docs ↗
OpenAI Codex	Not documented Cloudflare Workers has an official MCP server and OpenAI Codex supports MCP, but Cloudflare Workers's docs don't name this pairing. Auth setup may differ. Cloudflare Workers MCP docs ↗OpenAI Codex MCP docs ↗	Confirmed OpenAI Codex can run code; Cloudflare Workers publishes an API. OpenAI Codex docs ↗	Confirmed Only in the ChatGPT desktop app; not in the Codex CLI or IDE extension OpenAI Codex browser docs ↗	Confirmed Export from Cloudflare Workers, then works on local repositories OpenAI Codex docs ↗
Google Antigravity	Not documented Cloudflare Workers has an official MCP server and Google Antigravity supports MCP, but Cloudflare Workers's docs don't name this pairing. Auth setup may differ. Cloudflare Workers MCP docs ↗Google Antigravity MCP docs ↗	Confirmed Google Antigravity can run code; Cloudflare Workers publishes an API. Google Antigravity docs ↗	Confirmed Browser subagent via /browser, documented as an Antigravity App feature; the IDE has separate browser docs Google Antigravity browser docs ↗	Confirmed Export from Cloudflare Workers, then works on local projects and worktrees Google Antigravity docs ↗

Confirmed means both the tool's and the platform's official docs describe that route (links in the cell); IonBin has not tested every pairing. Not documented means it may work, but no official docs describe that route end to end. Checked Oct 17, 2026.
