Struct CallToolRequestParams 

#[non_exhaustive]
pub struct CallToolRequestParams {
    pub meta: Option<Meta>,
    pub name: Cow<'static, str>,
    pub arguments: Option<JsonObject>,
    pub task: Option<JsonObject>,
}

Parameters for calling a tool provided by an MCP server.

Contains the tool name and optional arguments needed to execute the tool operation.

This implements TaskAugmentedRequestParamsMeta as tool calls can be long-running and may benefit from task-based execution.

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.

meta: Option<Meta>

Protocol-level metadata for this request (SEP-1319)

name: Cow<'static, str>

The name of the tool to call

arguments: Option<JsonObject>

Arguments to pass to the tool (must match the tool’s input schema)

task: Option<JsonObject>

Task metadata for async task management (SEP-1319)

Implementations

impl CallToolRequestParams

pub fn new(name: impl Into<Cow<'static, str>>) -> Self

Creates a new CallToolRequestParams with the given tool name.

pub fn with_arguments(self, arguments: JsonObject) -> Self

Sets the arguments for this tool call.

pub fn with_task(self, task: JsonObject) -> Self

Sets the task metadata for this tool call.

Trait Implementations

impl Clone for CallToolRequestParams

fn clone(&self) -> CallToolRequestParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CallToolRequestParams

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

Formats the value using the given formatter.

impl Default for CallToolRequestParams

fn default() -> CallToolRequestParams

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CallToolRequestParams

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for CallToolRequestParams

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 CallToolRequestParams

fn eq(&self, other: &CallToolRequestParams) -> 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 RequestParamsMeta for CallToolRequestParams

fn meta(&self) -> Option<&Meta>

Get a reference to the meta field

fn meta_mut(&mut self) -> &mut Option<Meta>

Get a mutable reference to the meta field

fn set_meta(&mut self, meta: Meta)

Set the meta field

fn progress_token(&self) -> Option<ProgressToken>

Get the progress token from meta, if present

fn set_progress_token(&mut self, token: ProgressToken)

Set a progress token in meta

impl Serialize for CallToolRequestParams

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TaskAugmentedRequestParamsMeta for CallToolRequestParams

fn task(&self) -> Option<&JsonObject>

Get a reference to the task field

fn task_mut(&mut self) -> &mut Option<JsonObject>

Get a mutable reference to the task field

fn set_task(&mut self, task: JsonObject)

Set the task field
