-## SlashCommand Tool
+## MCP Permission Syntax
 
-Claude can programmatically invoke custom slash commands using the SlashCommand tool.
+Control MCP server access using permission syntax in settings:
+
+**Server-level permissions:**
+- `mcp__github` - Access entire GitHub MCP server
+- `mcp__github__*` - Wildcard access to all tools in GitHub server
+- `mcp__github__get_issue` - Specific tool access
+
+**Usage in permissions:**
+```json
+{
+  "permissions": {
+    "blocked": ["mcp__github__*"],
+    "requireConfirmation": ["mcp__jira__create_issue"]
+  }
+}
+```
+
+This allows fine-grained control over which MCP tools Claude can use.
