# Every MCP server in Claude Code, behind one endpoint.

Point Claude Code at a single onemcp portal instead of wiring up server after server. One `claude mcp add`, and your whole toolset is available — without stuffing hundreds of tool definitions into every prompt.

## Connect Claude Code in three steps

1. **Create a portal** — Group the MCP servers you want into a onemcp portal and authenticate each one once.
2. **Add one command** — Run a single `claude mcp add` with your portal URL — no per-server config in Claude Code.
3. **Let the agent script** — Claude Code discovers tools on demand and calls them through Code Mode, in one round-trip.

Run in your terminal:

```
claude mcp add onemcp --transport http https://portal.onemcp.dev/mcp
```

## Why route Claude Code through onemcp

- **One endpoint, every tool** — Swap or add upstream servers in the portal; Claude Code never needs reconfiguring.
- **Credentials stay host-side** — Native upstream OAuth and tokens live in the portal, never in your Claude Code config.
- **A lighter context window** — Three meta-tools replace hundreds of definitions, so Claude Code spends its context on your task.

## Give Claude Code its tools in one line.

Spin up a portal, run one command, and let Claude Code do the rest.
