MCP servers are outside programs that give Claude Code extra tools. For some servers, it now returns only the general message \"mcp_read_resource: could not read the resource\".\n\n**Why**\n\nYou and Claude may see less detail about why a resource could not be read.\n\n- Area: MCP\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
