"""Discovery must refuse to spawn a credential-driven MCP server that has no credentials yet.
The Slack case: a tokenless `npx slack-mcp-server` dies at boot and the npm wrapper buries the one
useful line under a Node crash dump, which is exactly the toast users saw. The right answer is a
clean 409 before any spawn, and an untouched spawn path once credentials exist.
