Emtpy GET request every second

[xurtian-lpit]

Inspector Version
v0.20.0

Describe the bug
After successful connection MCP Inspector sends a GET request every second with no query string and no body.

Expected behavior

Every MCP request and notification must include a method property because MCP messages follow JSON-RPC 2.0, which mandates method for all request/notification messages. Expected is that no empty requests are sent by MCP Inspector.

Environment (please complete the following information):

• OS: MBP
• Firefox 147.0.3 (aarch64)

When responding with either of:

[MCP] <= {"jsonrpc":"2.0","id":null,"error":{"code":-32600,"message":"Invalid Request","data":"Request is an empty array"}}
response status code: 200

or:

[MCP] <= {"jsonrpc":"2.0","id":null,"error":{"code":-32700,"message":"Parse error","data":"Invalid JSON"}}
response status code: 304

it keeps sending an empty request every second.

When responding with response status code 500. It will stop after a single attempt.

In all cases you wouldn't know there is an error when looking at the browser interface only, everything works fine there. Can list and execute tools.
