During pentest I've got the message:

Error processing streamed response event: Error invoking MCP tool do-nuclei: MCP error -32602: Invalid arguments for tool do-nuclei: [
{
"validation": "url",
"code": "invalid_string",
"message": "Invalid url",
"path": [
"url"
]
}
]

my map.json include next text:

{
  "name": "Nuclei Scanner",
  "params": {
    "command": "npx",
    "args": [
      "-y",
      "gc-nuclei-mcp"
    ],
    "env": {
      "NUCLEI_PATH": "/opt/homebrew/bin/nuclei"
    }
  },
  "cache_tools_list": true
},

nuclei is in the PATH and runs from command line without any problems

Any ideas ?
