Although server doesn't support completions, inspector sends them #436
Description
My custom MCP Server doesn't state that it supports completions in the initialize response. Still the inspector - if you type in a search box - sends completion requests. In my case for resource template fields.
{"jsonrpc":"2.0","id":10,"method":"completion/complete","params":{"_meta":{"progressToken":10},"argument":{"name":"query","value":"1232"},"ref":{"type":"ref/resource","uri":"users://search?q={query}&page={page}&limit={limit}"}}}
To Reproduce
have a resource template and start typing a parameter. e.g.
{
"resourceTemplates": [
{
"uriTemplate": "users://{user_id}/greeting",
"name": "getUserGreeting",
"description": "Returns a greeting for a user by ID"
},
{
"uriTemplate": "users://search?q={query}&page={page}&limit={limit}",
"name": "searchUsers",
"description": "Searches users with a query and optional page/limit"
}
]
}
Expected behavior
No completion request should be sent to the server it it hasn't explicitly stated that it does support completions.
