One agentic OS, four hosts: Claude, Cursor, ChatGPT, Codex
An agentic OS for Claude Code is not a different product from the one Cursor or ChatGPT runs. It is the same operative system, reached through MCP, on the host you already pay.
Four clients, one control plane
Most write-ups pick one tool and stop. Agentik hosts Cursor, Claude, ChatGPT, Codex, and Hermes. The install command points at https://mcp.agentik-os.com/api/mcp. agentik-os.com is the public site. It does not answer the MCP call.
A connector in Claude and a remote MCP server are not the same sentence. A connector is the client’s way in. MCP is the protocol. Agentik is the operative system on the other side of that protocol.
What changes per host, and what does not
The click path changes. Cursor reads an MCP config. Claude uses connectors. ChatGPT uses its connector flow. Codex uses its MCP server setting. The OS on the other end does not change: same agents, same memory rule, same refusal to buy your tokens.
OAuth and the issuer stay on the MCP host. If a guide tells you to point discovery at the marketing domain, it is wrong.
| Host | What you configure | Endpoint |
