## Motivation and Context PR #248 introduced server conformance testing using `@modelcontextprotocol/conformance`. This extends coverage to the client side so that `MCP::Client` behavior can also be validated against the MCP specification. ### Scope Client conformance is driven by the conformance runner, which spawns test servers for each scenario and invokes `conformance/client.rb` against them. The client script delegates the MCP initialize handshake to `MCP::Client#connect` and executes scenario-specific operations (for example listing tools or calling a tool). ### Usage Run all conformance tests (server + client): ```console bundle exec rake conformance ``` Run a single client scenario: ```console bundle exec rake conformance SCENARIO=initialize ``` List available scenarios: ```console bundle exec rake conformance_list ``` ## How Has This Been Tested? Ran `bundle exec rake conformance` locally. - Server conformance: 40 passed, 0 failed. - Client conformance: 3 passed, 54 failed (all 54 listed in `expected_failures.yml`). ## Breaking Change No. This change only adds test infrastructure under `conformance/` and does not modify SDK behavior.
