+## Testing the MCP Server
+
+### Starting the Server
+
+Start the server with a configuration file:
+
+```bash
+./stackrox-mcp --config examples/config-read-only.yaml
+```
+
+Or using environment variables:
+
+```bash
+export STACKROX_MCP__CENTRAL__URL="central.example.com:8443"
+export STACKROX_MCP__TOOLS__VULNERABILITY__ENABLED="true"
+./stackrox-mcp
+```
+
+The server will start on `http://localhost:8080` by default (configurable via `server.address` and `server.port`).
+
+### Connecting with Claude Code CLI
+
+Add the MCP server to Claude Code using command-line options:
+
+```bash
+claude mcp add stackrox \
+  --name "StackRox MCP Server" \
+  --transport http \
+  --url http://localhost:8080
+```
+
+### Verifying Connection
+
+List configured MCP servers:
+
+```bash
+claude mcp list
+```
+
+Get details for a specific server:
+
+```bash
+claude mcp get stackrox
+```
+
+Within a Claude Code session, use the `/mcp` command to view available tools from connected servers.
+
+### Example Usage
+
+Once connected, interact with the tools using natural language:
+
+**List all clusters:**
+```
+You: "Can you list all the clusters from StackRox?"
+Claude: [Uses list_clusters tool to retrieve cluster information]
+```
+
