Error when using MCP server https://github.com/da-okazaki/mcp-neo4j-server

Steps to Reproduce:

1. Set up whois-mcp in mcp.json (mine is in the workspace version)
   "neo4j-graph-database": {
   "command": "npx",
   "args": [
   "-y",
   "@alanse/mcp-neo4j-server@0.1.1"
   ],
   "env": {
   "NEO4J_URI": "bolt://localhost:7687",
   "NEO4J_USERNAME": "neo4j",
   "NEO4J_PASSWORD": "${input:neo4j-password}"
   }
   }

neo4j-password is setup in inputs section
"inputs": [
{
"id": "neo4j-password",
"type": "promptString",
"password": true,
"description": "MCP: Password for Neo4J Graph database"
}
],

2. Setup a neo4j database on localhost and default port
   (may not be required as I think it fails before reaching the neo4j server)

3. In chat in Agent mode type Add a new person named John Doe who is 30 years old in Neo4J

Error message:

Failed to validate tool 9f1_execute_query: TypeError: Cannot use 'in' operator to search for 'type' in true

The tool works in the inspector debug tool (npx @modelcontextprotocol/inspector .)
