MCP: upgrade framework and test stateless tools/list - #2644
Merged
Merged
Conversation
RED: McpProtocolTest executes against MCP 1.13.0 and fails because the first tools/list POST returns HTTP 400 instead of 200.
GREEN: the same raw HTTP McpProtocolTest passes with MCP BOM 2.0.3 on Quarkus 3.38.1 and JDK 21. Both independent tools/list requests return complete results without Mcp-Session-Id.

Both DSE and HCD CI exposed four obsolete empty-metadata assertions after the framework upgrade. Require only serverInfo and validate its name and version. The two affected DSE integration classes pass locally: 17 tests, zero failures.

There was a problem hiding this comment.
Some nit picks, the test in McpProtocolTest needs a comment to explain why it works.

What this PR does:
Upgrades the MCP framework from 1.13.0 to 2.0.3. Tests verify tools/list without initialization or a session ID using protocol version 2026-07-28. This is the first PR in the MCP stack.
Which issue(s) this PR fixes:
Part of #2625, which remains open. Version restrictions still depend on quarkiverse/quarkus-mcp-server#1078.
Verification
All 381 focused tests passed with no failures, errors, or skips on the combined MCP stack with this cleanup. This was not an isolated PR run.
Packaged integration tests and manual client checks were not rerun in this sweep. Current-head CI passed unit tests and both DSE and HCD integration jobs.
