Struct MessageMcpRequest 

#[non_exhaustive]
pub struct MessageMcpRequest {
    pub connection_id: McpConnectionId,
    pub method: String,
    pub params: Option<Map<String, Value>>,
    pub meta: Option<Map<String, Value>>,
}

UNSTABLE

This capability is not part of the spec yet, and may be removed or changed at any point.

Request parameters for mcp/message.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

connection_id: McpConnectionId

The MCP-over-ACP connection this message is sent on.

method: String

The inner MCP method name.

params: Option<Map<String, Value>>

Optional inner MCP params.

If omitted or set to null, the inner MCP message has no params.

meta: Option<Map<String, Value>>

The _meta property is reserved by ACP to allow clients and agents to attach additional metadata to their interactions. Implementations MUST NOT make assumptions about values at these keys.

See protocol docs: Extensibility

Implementations

impl MessageMcpRequest

pub fn new( connection_id: impl Into<McpConnectionId>, method: impl Into<String>, ) -> MessageMcpRequest

pub fn params( self, params: impl IntoOption<Map<String, Value>>, ) -> MessageMcpRequest

Optional inner MCP params.

If omitted or set to null, the inner MCP message has no params.

pub fn meta( self, meta: impl IntoOption<Map<String, Value>>, ) -> MessageMcpRequest

The _meta property is reserved by ACP to allow clients and agents to attach additional metadata to their interactions. Implementations MUST NOT make assumptions about values at these keys.

Trait Implementations

impl Clone for MessageMcpRequest

fn clone(&self) -> MessageMcpRequest

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MessageMcpRequest

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MessageMcpRequest

fn deserialize<__D>( __deserializer: __D, ) -> Result<MessageMcpRequest, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl IntoV2 for MessageMcpRequest

Available on crate feature unstable_mcp_over_acp only.

type Output = MessageMcpRequest

The corresponding v2 draft type.

fn into_v2( self, ) -> Result<<MessageMcpRequest as IntoV2>::Output, ProtocolConversionError>

Converts this value into the corresponding v2 draft type.

impl JsonSchema for MessageMcpRequest

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for MessageMcpRequest

fn eq(&self, other: &MessageMcpRequest) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for MessageMcpRequest

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
