Cannot Create Lamba Function with Function URL via CCAPI MCP Server
Describe the bug
When attempting to create Lambda function with HTTP endpoint CCAPI MCP server is attempting to create tags for the Lambda URLs even with DEFAULT_TAGS=disabled. Lambda URLs inherently don't support tags, and the server is trying to inject them anyway which fails.
There is no tag attribute on the CF resource type definition for Lamba URL and there is no tag attribute on the FunctionUrlConfig Lambda API data type.
Expected Behavior
CCAPI MCP server is able to create a Lambda function with a function URL.
Current Behavior
CCAPI MCP server fails to configure a function URL because it tries to add tags despite "DEFAULT_TAGS": "disabled".
Reproduction Steps
Using Claude Desktop with CCAPI MCP server configured start a new chat using Sonnet 4.5 or Haiku 4.5:
"Using AWS MCP create a hello world Lambda with function URL, invoke the functional URL, and display logs."
Presumably the same behavior is exhibited in other MCP Host apps and models. That said my testing was limited to Claude Desktop 1.0.211 (57d46e) on Windows 11 Pro using CCAP MCP server latest as-of 11/2/2025 with env "DEFAULT_TAGS": "disabled".
"awslabs.ccapi-mcp-server": { "disabled": false, "timeout": 60, "type": "stdio", "command": "uv", "args": [ "tool", "run", "--from", "awslabs.ccapi-mcp-server@latest", "awslabs.ccapi-mcp-server.exe" ], "env": { "AWS_PROFILE": "default", "DEFAULT_TAGS": "disabled", "SECURITY_SCANNING": "disabled", "FASTMCP_LOG_LEVEL": "ERROR" } }
