Fixes cross-host graph rendering and moves widget uploads off the JSON/base64 tool transport.
- render graph data from the launcher result without a second tool call
- stream multipart uploads through one-time, short-lived upload sessions
- remove temporary widget diagnostics and redundant unit tests
Tested with Biome, TypeScript, 17 unit tests, a Wrangler deployment dry-run, and live graph rendering in ChatGPT and Claude. Authenticated E2E setup is currently blocked by the saved OAuth refresh session returning `invalid_grant: session not found`.
End-to-end tests that drive the deployed Supermemory MCP over streamable HTTP (no mocks):
- discovery: handshake + tool/resource/prompt listing
- identity: whoAmI, listProjects
- memory: save -> recall round-trip, profile variants, forget, container scoping
- graph/resources/prompts: memory-graph, fetch-graph-data, profile/projects, context
- oauth: protected-resource discovery chain, dynamic client registration,
token-endpoint negatives, and a real refresh -> access token round-trip
- auth: GET / info, 401 on missing/invalid token
- root-scope: x-sm-project scoping behavior
Tests skip without SUPERMEMORY_API_KEY (OAuth tier-D skips without its token env vars) so CI is safe without secrets. Adds vitest + a test:e2e script and documents running + the OAuth flow in apps/mcp/README.md.
