Struct McpToolBridge 

pub struct McpToolBridge { /* private fields */ }

A wrapper that exposes one MCP server tool as a xcodeai Tool.

Created by register_mcp_tools() — one bridge per tool returned by McpClient::list_tools().

Implementations

impl McpToolBridge

pub fn new(def: McpToolDefinition, client: Arc<Mutex<McpClient>>) -> Self

Construct a bridge for one MCP tool definition.

Arguments

• def — the tool metadata returned by list_tools()
• client — the shared MCP client connection to forward calls through

pub fn raw_name(&self) -> &str

Return the original (un-prefixed) tool name. Useful for logging and for constructing the tools/call request.

Trait Implementations

impl Tool for McpToolBridge

fn execute<'life0, 'life1, 'async_trait>( &'life0 self, args: Value, _ctx: &'life1 ToolContext, ) -> Pin<Box<dyn Future<Output = Result<ToolResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Forward the tool call to the MCP server and convert the result.

How it works

1. Lock the mutex to get exclusive access to the MCP connection.
2. Call McpClient::call_tool(raw_name, args).
3. Convert McpToolCallResult → ToolResult via format_mcp_result().

Error propagation

• If the MCP call itself fails (e.g. server crashed, network error), we return Ok(ToolResult { is_error: true, output: "<message>" }).
• If the MCP call succeeds but the tool reported an error (isError: true), the same pattern applies — the output contains the error text from the server.
