Repository evidence: exact_resource_repo. Not MCP-specific/comparable for MCP-server adoption. This corrects the earlier quick-review misidentification. It is distinct from the official modelcontextprotocol/go-sdk; keep as framework/resource, not server.
Package evidence: go_module_no_comparable_download_metric. Not MCP-specific/comparable for MCP-server adoption. No attributable public download metric was verified. This corrects the earlier quick-review misidentification. It is distinct from the official modelcontextprotocol/go-sdk; keep as framework/resource, not server.
