Struct McpHandler 

pub struct McpHandler { /* private fields */ }

Executes one tool discovered from an MCP server.

A handler with no client is used only while normalizing the discovered tool metadata stored on McpToolParam into model-visible function tools.

Implementations

impl McpHandler

pub const fn discovered_tool_spec_only() -> Self

pub fn tool_call(client: Arc<McpClient>) -> Self

pub async fn discovered_tool_handlers( server_label: &str, client: Arc<McpClient>, allowed_tools: Option<&[String]>, ) -> Result<Vec<McpDiscoveredHandler>, ToolError>

Discovers and normalizes the tools exposed by one MCP server.

Errors

Returns ToolError::Execution when the server’s tools/list operation fails or times out.

pub const fn spec_from_param(_param: &Value) -> Self

Returns the spec-only MCP tool handler used during request normalization.
