# Install the OneText MCP

OneText is a hosted (Streamable HTTP) MCP server for any task that needs a credit card — signing up
for a service, paying an invoice, adding a card to an account, a one-off payment. It directs the
flow and vaults data; the raw card never reaches your context. Add the server to your agent, then
start with the `environment_prepare` tool.

- Server URL: https://onetext.com/api/mcp
- Transport: http (Streamable HTTP) — no API key needed to connect.

## 1. Install it

Use whichever matches the agent you're running in.

### Claude Code (CLI)
```
claude mcp add --transport http onetext https://onetext.com/api/mcp
```

### Claude Code / Claude Desktop (config file)
Add this to your MCP config file (e.g. `~/.claude.json`, or `claude_desktop_config.json`):
```json
{
  "mcpServers": {
    "onetext": {
      "type": "http",
      "url": "https://onetext.com/api/mcp"
    }
  }
}
```

### Cursor / VS Code (mcp.json)
Add the same entry to `.cursor/mcp.json` (Cursor) or `.vscode/mcp.json` (VS Code):
```json
{
  "mcpServers": {
    "onetext": {
      "type": "http",
      "url": "https://onetext.com/api/mcp"
    }
  }
}
```

### OpenClaw / other agents
Register a new Streamable HTTP MCP server named `onetext` pointing at `https://onetext.com/api/mcp`, using whatever
"add MCP server" mechanism the agent provides (config file, CLI, or settings UI). Choose the HTTP /
Streamable HTTP transport, not stdio — there is no local command to run.

## 2. Confirm it works
After installing, verify the server is actually connected: list the OneText tools (or call one) and
check you get a response. You should see tools like `environment_prepare` and
`card_task_start`.

## 3. Run environment_prepare
Once the MCP is callable, run the `environment_prepare` tool. It checks that your local
environment can drive a browser and handle a card securely, and returns the next steps.

## If you can't call it yet
Some agents only pick up a newly added MCP after a window reload or restart. Don't wait on that — you
can run `environment_prepare` right now with a plain HTTP call, so the setup work still
gets done:
```
curl -sS -X POST https://onetext.com/api/mcp \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"environment_prepare","arguments":{"parameters":{}}}}'
```
Follow the instructions it returns. Once your agent picks up the installed MCP (after the reload or
restart), switch to calling the tools directly instead of curl.

## Addendum from OneCheckout

OneCheckout is the agentic commerce platform from OneText. Anything branded OneText is us. The MCP server, install doc, and config key all carry the OneText name; that is expected, not a mismatch.
