-This is a [Model Context Protocol (MCP)](https://modelcontextprotocol.io/introduction) server that supports remote MCP connections, with Cloudflare OAuth built-in.

-You should use this as a template to build an MCP server for Cloudflare, provided by Cloudflare at `server-name.mcp.cloudflare.com`. It has a basic set of tools `apps/template-start-here/src/tools/logpush.tools.ts` — you can modify these to do what you need
+It integrates tools powered by the [Cloudflare One CASB API](https://developers.cloudflare.com/cloudflare-one/applications/scan-apps/) to
+identify security misconfigurations across your SaaS application integrations.

-#### Set up a KV namespace
+This MCP server is still a work in progress, and we plan to add more tools in the future.
 
-- Create the KV namespace:
-  `wrangler kv:namespace create "OAUTH_KV"`
-- Update the Wrangler file with the KV ID
+### Prompt Examples
 
-#### Deploy & Test
+- `List all my CASB integrations.`
+- `Are there any security findings for my Google Workspace integration?`
+- `Show me all assets for integration <id>.`
+- `What asset categories are available for Microsoft?`
 
-Deploy the MCP server to make it available on your workers.dev domain
-` wrangler deploy`
+## Access the remote MCP server from any MCP Client
 
-Test the remote server using [Inspector](https://modelcontextprotocol.io/docs/tools/inspector):
+If your MCP client has first class support for remote MCP servers, the client will provide a way to accept the server URL (`https://casb.mcp.cloudflare.com`) directly within its interface (for example in [Cloudflare AI Playground](https://playground.ai.cloudflare.com/)).
 
+If your client does not yet support remote MCP servers, you will need to set up its respective configuration file using [mcp-remote](https://www.npmjs.com/package/mcp-remote) to specify which servers your client can access.
+
+Replace the content with the following configuration:
+
+```json
+{
+	"mcpServers": {
+		"cloudflare": {
+			"command": "npx",
+			"args": ["mcp-remote", "https://casb.mcp.cloudflare.com/mcp"]
+		}
+	}
+}
 ```
-npx wrangler deploy
-```
+
+Once you've set up your configuration file, restart MCP client and a browser window will open showing your OAuth login page. Proceed through the authentication flow to grant the client access to your MCP server. After you grant access, the tools will become available for you to use.
