MCP server with basic auth and AIAgent

[hariraogotit]

Team,

I followed https://mcp.http4k.org/ and I am running a MCP server locally http://localhost:3000/mcp with basic auth security.

I then created an ai agent using AIAgent. In AIAgent I am passing toolRegistry. From https://docs.koog.ai/model-context-protocol/ I understand I can use

1. McpToolRegistryProvider.defaultSseTransport but how do I pass basic auth?
2. In McpToolRegistryProvider.fromClient it says mcpClient = existingMcpClient. How do I create a mcp client for this? I am unable to use http clients from mcp sdk and agent ai sdk seems to be expecting io.modelcontextprotocol.kotlin.sdk.client.Client.

Any leads will help please?

Hi @hariraogotit

You can instantiate SseClientTransport from mcp kotlin-sdk that accepts a Ktor HttpClient, where you can configure authentication (e.g., Basic auth) (ktor doc)
After that, either create an MCP Client with this transport and pass it to fromClient(...), or call fromTransport(...) and pass the transport directly
