Struct StatelessRequest 

pub struct StatelessRequest {
    pub version: Option<ProtocolVersion>,
    pub client_caps: CapabilitySet,
    pub client_info: Option<PeerInfo>,
    pub server_info: Option<PeerInfo>,
}

What a stateless 2026-07-28 request said about itself.

Fields

version: Option<ProtocolVersion>

io.modelcontextprotocol/protocolVersion from the request’s _meta.

client_caps: CapabilitySet

The capabilities the client advertised in _meta.

client_info: Option<PeerInfo>

The client identity from io.modelcontextprotocol/clientInfo.

server_info: Option<PeerInfo>

The server identity to stamp into each result’s _meta.

Implementations

impl StatelessRequest

pub const fn empty() -> Self

A request with nothing in its _meta.

pub const fn with_version(self, version: ProtocolVersion) -> Self

The version the request advertised in its _meta.

A request whose _meta carried no version leaves this unset, and the server picks the revision to answer on.

pub const fn with_client_caps(self, caps: CapabilitySet) -> Self

Replaces the advertised capability set rather than merging into it. A request that advertised none carries an empty set.
