added auth

[shreymodi1]

added support for auth in mcp.

people can now use

{
{
"mcpServers": {
"": {
"url": "",
"authorization": "any token or authorization key with support for replacement of env variables ($API_KEY)"
}
}
}
}

Note

Adds authorization to MCPConfigurationServerUrl and sends it as an Authorization header (supporting $VAR/${VAR} env substitution) when connecting to HTTP MCP servers.

• MCP HTTP client:
  • Use authorization from MCPConfigurationServerUrl to build Authorization header; pass to streamablehttp_client(url, headers=...).
  • Add _process_headers to substitute environment variables ($VAR/${VAR}) and validate presence, raising if missing.
• Config Models:
  • Add optional authorization to MCPConfigurationServerUrl.
