Struct ToolMetadata 

pub struct ToolMetadata {
    pub name: String,
    pub title: Option<String>,
    pub description: String,
    pub parameters: Value,
    pub output_schema: Option<Value>,
    pub method: String,
    pub path: String,
    pub security: Option<Vec<String>>,
}

Internal metadata for tools generated from OpenAPI operations.

This struct contains all the information needed to execute HTTP requests and is used internally by the OpenAPI server. It includes fields that are not part of the MCP specification but are necessary for HTTP execution.

For MCP compliance, this struct is converted to rmcp::model::Tool using the From trait implementation, which only includes MCP-compliant fields.

Fields

name: String

Tool name - exposed to MCP clients

title: Option<String>

Tool title - human-readable display name exposed to MCP clients

description: String

Tool description - exposed to MCP clients

parameters: Value

Input parameters schema - exposed to MCP clients as inputSchema

output_schema: Option<Value>

Output schema - exposed to MCP clients as outputSchema

method: String

HTTP method (GET, POST, etc.) - internal only, not exposed to MCP

path: String

URL path for the API endpoint - internal only, not exposed to MCP

security: Option<Vec<String>>

Security requirements from OpenAPI spec - internal only, not exposed to MCP

Implementations

impl ToolMetadata

pub fn requires_auth(&self) -> bool

Check if this tool requires authentication based on OpenAPI security definitions

Trait Implementations

impl Clone for ToolMetadata

fn clone(&self) -> ToolMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolMetadata

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

Formats the value using the given formatter.

impl From<&ToolMetadata> for Tool

Converts internal ToolMetadata to MCP-compliant Tool.

This implementation ensures that only MCP-compliant fields are exposed to clients. Internal fields like method and path are not included in the conversion.

fn from(metadata: &ToolMetadata) -> Self

Converts to this type from the input type.

impl Serialize for ToolMetadata

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
