Add a conformance testing pipeline that validates the Python SDK against the @modelcontextprotocol/conformance npm package. Changes: - Add conformance-client example that handles all test scenarios (auth flows, metadata, scope handling) - Add run-server-conformance.sh script to test the everything-server - Add GitHub Actions workflow with server-conformance and client-conformance jobs - Both jobs use continue-on-error: true to match TS SDK approach The conformance client supports: - OAuth authorization code flow (default) - Client credentials with client_secret_basic - Client credentials with private_key_jwt - All auth/metadata and sep-835 scope scenarios Test results: - Server: 24/24 passed - Client: 192/192 passed (metadata, auth, sep-835 suites)
The --all-packages flag triggers a pre-existing issue where mcp-simple-chatbot is missing its README.md. Use --package to install only the specific packages needed for each job.
The conformance package requires either --suite or --scenario. The newer version (0.1.10) supports --suite all.

Can this not be a package, and not be in examples? You can create its own GitHub action for it under .github/actions, and use it in conformance.yml.
- Extract shared default_elicitation_callback that applies schema defaults from ElicitRequestFormParams.requested_schema.properties.*.default - Add elicitation callback to _run_auth_session so all OAuth flows advertise elicitation capability - Call first available tool dynamically instead of hardcoded test-tool - Add results/ directory to .gitignore
