MCP servers are allowed by spec to paginate list responses. The old
implementation made a single request and stopped, silently dropping
subsequent pages. Servers that paginate at fewer items than their
total tool count (e.g. gbrain at 5 per page) would appear to expose
only those first few tools.
All four discovery methods now follow nextCursor until the server
signals no more pages, accumulating results across all pages:
- discover_tools
- discover_resources
- discover_resource_templates
- discover_prompts
Thanks to Liu-Vince for the original diagnosis and fix (PR #1256).
