fix(mcp): answer resources/prompts discovery with empty lists, not -32601#1015
Merged
Conversation
…2601 Clients like Cline probe resources/list, prompts/list and resources/templates/list on connect regardless of declared server capabilities; the -32601 Method-not-found errors surfaced as a failed connection (status=error) even though tools worked fine. Empty lists are the interoperable answer for a tools-only server. Reproduce-first: mcp_discovery_methods_return_empty_lists is RED on the unhandled dispatch (Method not found) and GREEN with the empty lists. Closes #958 Signed-off-by: Martin Vogel <martin.vogel.tech@gmail.com>

Closes #958.
Cline (and other MCP clients) probe
resources/list,prompts/list, andresources/templates/liston connect regardless of declared capabilities. This server answered-32601 Method not found, which Cline surfaces as a failed connection (status=error) even though tools work fine. Reproduced locally against the current binary: all three methods errored.Fix: empty lists (
{"resources":[]},{"prompts":[]},{"resourceTemplates":[]}) — the interoperable answer for a tools-only server.Reproduce-first:
mcp_discovery_methods_return_empty_lists— RED on the unhandled dispatch, GREEN with the fix; mcp suite 148/148; lint-ci clean.
