Struct InitializeCapabilities 

pub struct InitializeCapabilities {
    pub experimental_api: Option<bool>,
    pub explicit_gateway_oauth: Option<bool>,
    pub extensions: Option<BTreeMap<String, Value>>,
    pub mcp_server_openai_form_elicitation: Option<bool>,
    pub opt_out_notification_methods: Option<Vec<String>>,
    pub request_attestation: Option<bool>,
    pub required_human_approval: Option<bool>,
}

Client-declared capabilities negotiated during initialize.

Fields

experimental_api: Option<bool>

Opt into receiving experimental API methods and fields.

explicit_gateway_oauth: Option<bool>

Use explicit gateway OAuth login instead of automatic browser authorization. Applies to this app-server’s gateway runtime; later connections cannot undo it.

extensions: Option<BTreeMap<String, Value>>

MCP extension settings declared by the app-server client.

mcp_server_openai_form_elicitation: Option<bool>

Legacy opt-in for the openai/form MCP extension.

New clients should declare openai/form in Self::extensions.

opt_out_notification_methods: Option<Vec<String>>

Exact notification method names that should be suppressed for this connection (for example thread/started).

request_attestation: Option<bool>

Opt into attestation/generate requests for upstream x-oai-attestation.

required_human_approval: Option<bool>

Present humanCommand approvals to a person and return only a one-time decision. Requires experimentalApi. Pending requests can be replayed to compatible clients.
