## Summary
This PR introduces the **1chat MCP server** in Kibana, exposed at the
experimental `/api/mcp` endpoint behind a feature flag. It allows
external MCP clients (e.g. Claude Desktop, Cursor, OpenAI Agents) to
connect and use tools registered in the 1chat registry.
### MCP server
- Implements a **stateless** MCP server following the MCP spec
(Streamable HTTP transport).
- Supports **API key** and **basic auth** for authentication.
- Works with clients via:
- **Streamable HTTP** with auth header
- **STDIO** transport using `mcp-remote` proxy
- Endpoint under a feature flag `xpack.onechat.mcpServer.enabled`
- 1chat tools are scoped to the caller’s permissions, as determined by
the auth header.
### Other changes
- Implemented `KibanaMcpHttpTransport` (mcp http transport layer adapted
to Kibana Core primitives) + tests
### Local testing
Set ui setting: `onechat:mcpServer:enabled` to true
E.g. add this to Claude Desktop:
```
{
"mcpServers": {
"elastic": {
"command": "npx",
"args": [
"mcp-remote",
"https://{kbn}/api/mcp",
"--header",
"Authorization: ApiKey ${API_KEY}"
],
"env": {
"API_KEY": "..."
}
},
}
}
```
### Enable feature via API
```
POST kbn:/internal/kibana/settings/onechat:mcpServer:enabled
{"value": true}
```
