+## MCP Client Configuration
+
+To use this server with Cursor, Claude Desktop, or other MCP clients, add it to your MCP config:
+
+**Cursor** (`.cursor/mcp.json` or Cursor Settings → MCP):
+
+```json
+{
+  "mcpServers": {
+    "secure-sql": {
+      "command": "docker",
+      "args": [
+        "run",
+        "-i",
+        "--rm",
+        "--env-file", "/path/to/your/secrets",
+        "-v", "/path/to/your/policy:/run/policy:ro",
+        "ghcr.io/jrhuerta/secure-sql-mcp:v0.1.0"
+      ]
+    }
+  }
+}
+```
+
+**Claude Desktop** (`claude_desktop_config.json`): same structure under `mcpServers`.
+
+The `--env-file` should point to a file containing `DATABASE_URL` and `ALLOWED_POLICY_FILE=/run/policy/allowed_policy.txt` (see Environment Variables below). The volume mounts the policy directory read-only. Pull the image first: `docker pull ghcr.io/jrhuerta/secure-sql-mcp:v0.1.0`

 ## Security Model
 
 - Database credentials stay server-side (env vars), never in prompts.

 ## Secrets Best Practices
 
 - Put credentials only in `.env` (or your secret manager), never in prompts.
