HTML page: https://policylayer.com/tools/mcp-dev/get-media-type-allowed-children ## Facts - Tool: `get-media-type-allowed-children` - Server: Mcp Dev (`@umbraco-cms/mcp-dev`) — https://policylayer.com/tools/mcp-dev.md - Install: `npx -y @umbraco-cms/mcp-dev` - Homepage: git+https://github.com/umbraco/Umbraco-CMS-MCP-Dev.git - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "get-media-type-allowed-children", "arguments": {} } } ``` ## Why get-media-type-allowed-children is rated Low This tool retrieves configuration metadata about allowed child media types within Umbraco CMS. It performs a read-only query operation that returns existing data without creating, modifying, deleting, or executing any operations. The blast radius if misused is minimal, as the worst outcome would be information disclosure of schema/structure data. From the tool's own definition: "Tool name 'get-media-type-allowed-children' and description 'Gets the media types that are allowed as children of a media type' indicate a retrieval/query operation with no side effects."
