Defined in:
lib/mcp/client.rb

Overview

Raised inside a server-to-client request handler (registered via on_server_request, e.g. on_sampling) to answer the request with a specific JSON-RPC error code instead of the default internal error. Mirrors the TypeScript SDK's McpError and the Python SDK's ErrorData return: for example, the sampling spec answers a rejected request with code -1. https://modelcontextprotocol.io/specification/2025-11-25/client/sampling
