ClientCapabilitiesBuilder

DSL builder for constructing ClientCapabilities instances.

This builder is used within InitializeRequestBuilder to configure client capabilities. All capabilities are optional - the presence of a capability indicates support for that feature.

Available Functions (all optional)

• sampling - Indicates support for sampling from an LLM

• roots - Indicates support for listing roots

• elicitation - Indicates support for elicitation from the server

• experimental - Defines experimental, non-standard capabilities

Example usage within buildInitializeRequest:

val request = buildInitializeRequest {
    protocolVersion = "1.0"
    capabilities {
        sampling(ClientCapabilities.Sampling())
        roots(listChanged = true)
        experimental {
            put("customFeature", JsonPrimitive(true))
        }
    }
    info("MyClient", "1.0.0")
}
