Bước 1: Tạo và cấu hình namespace KV Step 1: Create and Configure KV Namespace ជំហាន 1: បង្កើត និងកំណត់ namespace KV
- Chúng ta đang xây What we're building អ្វីដែលយើងកំពុងសង់
- A KV namespace bound to your MCP server, giving your tools persistent, globally distributed storage.
- Vì sao quan trọng Why this matters ហេតុអ្វីសំខាន់
- KV storage enables stateful applications where data persists between AI conversations and user sessions.
# Create a new KV namespace for our MCP server and choose the options below
npx wrangler kv namespace create "TODO_STORE"
⛅️ wrangler 4.64.0
───────────────────
Resource location: remote
🌀 Creating namespace with title "TODO_STORE"
✨ Success!
To access your new KV Namespace in your Worker, add the following snippet to your configuration file:
{
"kv_namespaces": [
{
"binding": "TODO_STORE",
"id": "abc1234567890defghij"
}
]
}
✔ Would you like Wrangler to add it on your behalf? … yes
✔ What binding name would you like to use? … TODO_STORE
✔ For local dev, do you want to connect to the remote resource instead of a local resource? … noAnswer yes to let wrangler add the binding, use TODO_STORE as the binding name, and no for remote local dev.
Answer yes to let wrangler add the binding, use TODO_STORE as the binding name, and no for remote local dev.
