-
Configure the plugin with the settings below

From the repository
cd ai
npm install
1. npx wrangler kv namespace create OAUTH_KV
2. Follow the guidance to add the kv namespace ID to wrangler.jsonc
3. npm run deploy
Just like you did above in "Develop locally", run the MCP inspector:
npx @modelcontextprotocol/inspector@latest
Then enter the workers.dev URL (ex: worker-name.account-name.workers.dev/sse) of your Worker in the inspector as the URL of the MCP server to connect to, and click "Connect".
You've now connected to your MCP server from a remote MCP client.
