Struct McpBackend 

pub struct McpBackend { /* private fields */ }

Tool backend for executing tools via MCP servers

Implementations

impl McpBackend

pub async fn new( server_name: String, transport: McpTransport, tool_filter: ToolFilter, ) -> Result<McpBackend, ToolError>

Create a new MCP backend

Trait Implementations

impl Drop for McpBackend

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl ToolBackend for McpBackend

fn execute<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, tool_call: &'life1 ToolCall, _context: &'life2 ExecutionContext, ) -> Pin<Box<dyn Future<Output = Result<ToolResult, ToolError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, McpBackend: 'async_trait,

Execute a tool call in this backend’s environment

fn supported_tools<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Vec<String>> + Send + 'async_trait>>

where 'life0: 'async_trait, McpBackend: 'async_trait,

List the tools this backend can handle

fn get_tool_schemas<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Vec<ToolSchema>> + Send + 'async_trait>>

where 'life0: 'async_trait, McpBackend: 'async_trait,

Get API tool descriptions for this backend

fn metadata(&self) -> BackendMetadata

Backend metadata for debugging and monitoring

fn health_check<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>

where 'life0: 'async_trait, McpBackend: 'async_trait,

Check if the backend is healthy and ready to execute tools

fn requires_approval<'life0, 'life1, 'async_trait>( &'life0 self, _tool_name: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<bool, ToolError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, McpBackend: 'async_trait,

Check if a tool requires approval before execution
